 Thank you very much for joining my session here. I am Eric. I am a normal user which means I'm not a developer and I love free software and That is the main reason why for a long time I resisted to get myself a smartphone because actually I I think I had no choice because either I could get myself an iPhone But then I get locked into the Apple proprietary world or I could get myself an Android and Then I get locked into the Google tracking And I didn't want it both until someone told me about custom ROMs which are basically forks from Android without the Google apps and About fdroid, which is a free software app repository That delivers you hundreds and thousands of free software apps and since then now I'm a happy Smartphone user using free software on my smartphone and today I wanted to share my experience with that and Hopefully enable you also to achieve freedom on your devices. Oh now is my screen off here. It's also there of It's not my computer, so I Hope it works out Yeah, so I wanted to share my experience that I have with fdroid with you And first I wanted shortly know who of you knows already after it That's quite a lot. Okay, that's cool so then I hope I can tell you something new and share my My best apps that I know from after it. I Will shortly talk about Android and and free software and the fresh after environment with Android and then I will talk about fdroid so I guess you all know especially as you use a lot of fdroid here a lot of fdroid users here I guess you know what it's free software But just to be sure when I say free software then I talk about the software that gives you the for freedom for freedoms to use study share and improve the software the Problem with the Android system basically is the the Android system itself is a Linux-based operating system and it's free software but by default it's delivered with Google apps and They are not free software. They are proprietary software. So Gmail g-maps YouTube and so on So you get by default you get binary blobs on your system and maybe worse Normally you buy a phone if you do not buy an exos you buy a phone with a third-party reseller They add more proprietary software on it like Facebook app or Amazon or whatever soccer app what is out there and So by default you have binary blobs on your phone That is a problem because you don't know the usual problems you have this proprietary software You don't know exactly what it is doing And you cannot control what it is doing and in this case often with Android you cannot even uninstall it. So You are lost with that the solution to this in short, but it's actually a very complex topic and Very technical, but in short the solution to this is you can root your phone and when you root your phone Then afterwards you can install Alternative operating system So this is Basically called custom ROMs because that the Android system is a free software system There are forks out there and they can use the system itself and Then they can free it from the Google apps and then they republish it as you are used to do with free software So you can get these custom ROMs and install them on your phone There is a whole universe out there with different custom ROMs Serving different needs and aspects of software and I have here the I have just chosen to to show you because Replicant the first year is Custom ROM developed by the FSF the free software foundation and It has basically it's a hundred percent free software down to the driver It's all free software. So if you really into the free software, this is the this is the custom ROM to choose But does not work with every phone and so in contrast. I have your line HOS. That's a very popular custom ROM It uses the drivers the original drivers from the manufacturer But therefore it also works with a lot of phones out there So once you have the custom ROM then you can install asteroid what is this talk about and This is also the easiest option here. This is the the logo from asteroid this is also the easiest step in the whole process and You can also start backwards and if you do not yet know after it here You can basically you can also install it on your normal Android phone You can directly start basically while I'm giving my talk you can aside You can install asteroid and check out the nice features that I tell you And that's why I wanted to focus on This step here in my talk So as I already said asteroid is a free software app repository. So it's basically similar to you know from the Google Play Store or Amazon Marketplace or things like that You have a repository full of Only in this case only free software apps and also it's a client and with that client You can access this repository the thing is to To get the client once you have to download it from the internet Because it's not in in competitive stores for competitive competition reasons They don't offer this so I Mean you can search it internet or type in that that world So we have to download it once and install it and then once you have it installed Then it basically looks like this if you started the first time this is how your screen looks like and what you see here is the latest The newest changes to do the repository So either the newest app or if there was an update on some on an already existing app It will also appear again here in the stream And it's the design is with the tiles Yeah, so you see latest apps here Then you have a search function also here to look for apps if you search for an app and You have a category section where you can browse apps by topics if you look for games or development or office or whatever category you're looking for you can browse the Repository and you will see all the apps if you Think deeper. So if you choose for an app, you want to look at an app Then you get this view here. So you see a description of the app. You see the latest Change log a description and you also see anti anti features so you are warned depending on the app what what it does so it for example it tracks your GPS activity or in this case because new pipe is a free software replacement for the YouTube app in this case it says so this app promotes non-free network services and If you scroll this is basically if you scroll further down You see more options. So you see the option to donate for the developers You see all kind of meta information. You see the license that is used. You see you can access the source code the website and so on and Really nice. I think is also that you see minimum the latest free versions of the app So you can downgrade upgrade as you like Because maybe you don't like the new features improved or it does not work with your system or something So it gives you here the full control over the version that you like to use and talking about the donations It's the it's this time of the year, but also in other times of the year I want to use this occasion to say free software heavily depends also on your financial contributions help if you like free software choose Choose some project that you like to support Please consider donating and protect freedom by doing that going on Of course, you also have an administration interface in asteroid. There's a lot of things that you can do. I want to highlight The that you can of course you can manage your the apps that you have installed via asteroid and you can manage the repositories that You use which I will explain in a minute On this slide. I want to highlight here more that you can also use the tour services to connect with the with the repository if you are in need of advanced privacy and anonymity Then you can use the tour services here also with the asteroid Talking about in managing the installed apps. I Think it's very intuitively what you see here you have you see in this case the apps I have installed and That need an update and you can either and update them all at once or individually More interesting and maybe less Intuitively is the repositories so When you install asteroid by default it is connecting to the asteroid repository this repository is a collection of free software apps and free software apps only There are some things you have to apply to get into this Into the repository and Else you will not end up there, but what you can do you can also set up your own Repository or as a user you can add additional repositories. So in this case you see There is also the guardian project for example and the micro g Repository connected For the 35 c3 here. There's also a special repository With the schedule and with the c3 nav the power here is that you can use the asteroid client for Multiple for multiple Stuff so I was reading a very interesting story from Thorsten Grote He was in Cuba and in Cuba the bandwidth is very expensive. So They go Into they need basically Wi-Fi to to get more to get there to to download from the internet and there was this internet cafe and This internet cafe was offering there. They were setting up their own repository where they put apps in Also proprietary apps also non-free apps that they collected from other sources for the customers so they could download it there and this way they were spreading the Software basically to the people or if you are a developer and You have your software in the alpha or beta version or even in the final version Then you can also use these you can set up your own repository and spread your software via this repository and Even if you do not apply it to whatever the asteroid repository asked you to Yeah, we just had this you can add this is how it basically looks like if you add an own repository and You can also put a repository into the the onion web and After it can connect to this repository as well So this is also a very enhanced Privacy and anonymity feature finally the a very powerful Thing that after it can do is it can help you to share software without having the need of internet connection So if you don't have a internet connection you can nearby swap software so This is possible via Wi-Fi so if both devices are in the same Wi-Fi you can share your app with someone else or Or via Bluetooth even so in near field range I can share an app with someone else without both having internet connection and Even more you can if the other person does not have asteroid yet you can first send them asteroid and Then you can share the app This is I think a very very powerful feature in particular for maybe less developed regions or Regions in with less especially less internet connectivity or with so expensive remember the story from Cuba I told you people can go into the internet cafe download With the internet cafe repository Software they want to have go home share the software with their neighbors with their friends with their families This is a very powerful feature from after it so Is there any question so far because else I'm going now to To talk about some of the apps that you can find in asteroid and that I think are really cool to use and very helpful If there's some question now about the asteroid itself We could have one or two questions because of the time. We just have space for one or two. Yes, please Is this just just me or is somebody else having this problem? So the question was that you get an asteroid a later no, yes an older version Then you get in the Google Play Store, right? So it always tries to update the Yes, I understand. I guess this is because you have your Google services installed I'm I was not aware that because this is a very Recent change after it was not available in the Play Store. So until recently then It's what Not available officially. I hear from the side. So I don't know how you can get it then I Have no Google Play Store. I have I've really no expert of a Google Play Store. Just me. Thanks. How does it work? Yeah, so I guess Try to get rid of your Google Play Store and the problem is fixed So, yeah Good, then I go on here now. No, no, that was another question Okay, the second question and then I will go on because of the time and we can later have questions You're by swap. Does that mean that both persons have to have asteroid installed and the amp that they're swapping Has to be an app in the asteroid store and you have to have it freedom loaded as a user, right? And you can only It means that one of the persons has to have asteroid and the app has to be in the asteroid store Yes, okay Because this person then can first share send asteroid to the second person. Yeah, and after that swap the app The other person likes to have but if you then make your own custom repository You could pretty much send anything as long as in your custom repository in asteroid or is it just official? if the other person first Then it's the repository in this case Which my Then again have to have some internet connection for adding the repository Yeah, but if you have some repositories, I guess you first have to But if you have a cup of on speed and amount of downloading then adding repositories into as heavy as Having the repository and the loading things from it, right? Sorry. I didn't get it from you or if you have a cup on speed and amount of Don't load the data then adding repository and then getting the binary from a friend It's not the same as adding the repository and the downloading from the internet, right? It should end up with the same app So you can basically Of course, you can also yeah, you can save some bandwidth But I think I guess I mean the main powerful feature here is of course to share Software without from one device to the other without having the need of any internet or even Wi-Fi or something you can basically with the near field communication Bluetooth Technology, you can just swap software to the next device. I mean that is the main feature of it Okay, thanks But yeah, but if bandwidth is very expensive, of course, this is also where yeah like in Cuba then this is also a good thing Good I go on here now. We can later have questions again But as we had started a little bit late, I want to go on here There's just one one thing in asteroid. This is might be a little bit annoying, especially if you're new and this is There is no rating system first so if I start first start use after it I Have a hundreds of apps and sometimes multiple apps for the same thing. So I look for a text editor Then I get 12 different text editors or something or PDF viewers And I have no idea which is better which is worse. Why where do they differ or what is the experience with that? Because there's no common function. There's no rating system so I'm a little bit overload maybe and even if I This is I just did it like two hours before my talk now a search function You look for navigation. What do I get this first? I get fair email and then second Okay, this is to see three enough then I get something about my local files. I RSS feed this was not what I was maybe looking for if I'm look for a navigation software and That's why I Now want to show you some of the apps. I think are really helpful for you to make your first start steps and the start Talking about navigation. I travel a lot. So for me a Navigation software is very very in I'm having need of a navigation software and this is awesome and it's just the Perfect app for this. This is like a the how you say the Swiss Swiss knife for Navigation it's based on OpenStreetMap. You see a screenshot here on the right side OpenStreetMap, I guess, you know it's The better version of any other map No, it's It's like the Wikipedia version of a map. So it's Done by the users and by contributions and it's very very detail rich It's much much more in detail than the Google map is normally you can see here for here For example, you see you can see every tree and the way spin and and other stuff There's by the way, I have seen there's some OpenStreetMap booth over over here So they can tell you much more than I can do now But anyway OpenStreetMap, it's OpenStreetMap based and very good thing about OpenStreetMap based This app here is that you can download the map So I can download the map before I go somewhere and then again, I don't need any internet connection I go to Cuba or I go to Morocco or somewhere else. I Download the map before and then I have the full map on my mobile device I can be in flight mode. I have no need of any internet connection and I do not only have the full map I have a full offline navigation system. I can go from point one to pen B. I can record my trip. I have I have all the details with the if I'm a hiker and Whereas the better road for hiker or for the car if I drive with the car I even have voice guidance and multiple languages available Like going next crossing to the left or to the right and these kind of things and everything of this is offline And this is really really powerful and works perfect I have did I travel I use it for my travels since many years and It works really really good It's a very I know you can also by the way, you can also add Your own marks on the map so if you I don't know the place where you sleep or the place of the CCC or The best beer last night or something like this you can put on the map and find it again and You have a lot of add-ons also that you can use for example a hillshade layer Which if you are into hiking is very Nice to have so we can see where is the better road to walk the better path to go you also have the Altitude visible on the map and you have a much much more to Add-ons you have now take views and I don't know I'm using maybe 20% of what is available Just to say so it's a very complex system This add-on is really nice. I want to highlight Two more add-ons this one here is from Wikipedia and You can also download it and it shows you basically every Wikipedia page that has a GPS location will be shown on your map Including the text of the page the pictures are only available then online, but you can download the whole text Also and use it offline and when I go somewhere for my travels I spent that two three days and then I spent two three days more for discovering the city I am in you basically have your personal tourist guide in your pocket And you go somewhere to see oh, what is this for a nice church or monument or something? You can look it up and as you see also It's not only about buildings or or landmarks Everything that has a GPS mark like here in this case the place where Peter factor Was one of the first victims Of the Berlin walls border control So this is very interesting to use And the the other add-on if you are into mapping This is what I also really enjoy You have a very you have a add-on that makes it very simple to add information into the OpenStreetMap So when I go somewhere, there's a nice bar or whatever or shop or something that I And I see it is not yet on the OpenStreetMap It takes you one minute to mark the point Say what it is and upload it to OpenStreetMap and the world is just one bit better I think Osman is the best app that you can use and it's very complex, but I know from my friends many people might or some people might prefer a more Nice visual version So this is where maps me comes in there's also I think a both by the way both Some of the apps in this case both already hold you are also in other stores Sometimes they cost money even in asteroid. They are for no cost available always There's no in an asteroid. You have no account. You have no rating. You have nothing basically, but you can use you You can get everything Yeah, but that's it so As you can see here with maps me it has a very nice visualization of the buildings and So if you walk around if you are into this maps me is maybe the best choice It also has a navigation available But it's generally that's basically what it can do and it's the way way it's more simple than the osman I was telling you before to finish my OpenStreetMap My own street map related part Again, if you are into mapping street complete is a really nice app that I just discovered recently What it does is you can walk around and you see quests here that you can do like If you tip on it, then you will see what is this for a house number or what is the name of this road? What is the surface of this road and things like this and it's a little bit if you If you know about geocaching or something like this. It's a little bit similar. You have quests you can follow and again, you can Make the map with each contribution way better So I'm seeing my time. I have to maybe speed up a little bit Public transportation, so if you are traveling talking about traveling you also want to use public transportation Often because you have maybe no car with you. This is where transporter comes in. This is the app to use on the right side you see the those countries that are Colored are the countries where you have access to the long-distance Railways and all the dots that you can see are our major cities that were minor cities But cities anyway, where you have access to the full public transportation Network so I can use transporter for example to go from one Building in Paris to another building in Berlin and it will show me all the way Where I have to change and so on it looks very I guess intuitively so we have you say you want point a to point B and then it gives you the different options that you have and Where you have to change we have to walk what time how long it will take you as you I might expect it from a public transportation app and Since last year is a very cool feature you can also see the same your way on the map again on the open-suit map and If you go from A to B you are a tourist and then you say oh nice. I passed by the this monument the Brandenburg a tour the Whatever it might be Then you have this two-hour ticket you can just drop out Make a picture while have a walk Go back and and return to your way That's a nice feature. I think so so much about transportation and the old street maps when you are When with your mobile phone you also often like to access your emails There is K9 is the preferred app here K9 has a You can Basically you can add multiple email accounts to administrate you have unified inbox, but you can also administrate them individually with folders and You have a threading here. You see this on the right side. This is one email thread and Yeah, read and write emails with this application If you use open pgp then Here's the open Open keychain is the name of this app It's written here. I forgot to write it down here. So keychain is the the name of this app The so you can also Send and read write and read encrypted emails I personally do not do it because I don't like to have my private key on my mobile device in case I lose it but other people's do so and I heard it works pretty good and without any annoyances talking about mobile devices you also often like to synchronize the data you'd like to synchronize your contacts your calendars and Your even your data maybe So this is where daft droid comes in Daft droid can manage your contacts and your calendars to synchronize them with other devices basically with the any any computer connected to the internet like a server and Talk about server. So of course you need something that is connected to the internet is where I recommend next cloud Next cloud is also over here. They can I Guess they can tell you a way better and more than I can do but next lot in short is a Is a so you can use it on your server or on your on your web on your web space and And when you install it by default contacts and calendar is included and then you have this on the right side you can see here there's a like you know it from the Maybe from the proprietary competitor Dropbox then you have different options how to how to share your data with a link or something Or but in this case it's federated by the way, so we can also share it with other next loud instances And there is also an app for an X loud in the after a store so From my mobile to my next cloud to my running next loud instance, I can Access my data with the browser or with the next cloud client and I can sync my contacts and calendar with the devdroid app and This leads me basically into this situation so I Access my data from both devices either with the client because there's also a client for for the for GNU linux distributions, so I can either access my data with the client or the browser and Synchronize my contacts calendars for example with Thunderbird or any other client and From a mobile with the devdroid and this leads into the situation basically where I have both in sync And just using free software I'm personally a big music lover So I was very happy when I discovered the clementine remote app Clementine is a music player And with this app you can access the running application on your on your Linux distribution you have to be you have to access the same the same Wi-Fi and And Yeah, basically you can remote control your running music so you can play the next song or the last song I mean what you can do with music louder less loud and Get the mid-time formation in the music written in the music and A really really nice feature I think for me is you when you double tap the Running music then it tries to access the lyrics from the Kia and Yeah, so you can read also the lyrics while you sit on your couch and you control the music running. It's just awesome And as we are here on a conference, I guess you might go to other conferences as well There is a giggy tea or a gitchy tea or however you pronounce it. I say giggy tea now and giggy tea is used from multiple free soft especially free software, but generally multiple bigger conferences and You see here. This is a the example on the right side. You see from RMLL in France this year They had a lot of tracks. So each line is a track and then you see what is running the schedule that is running and And You can go into each of the sessions you get a description of the session you can set a reminder here and Then your mobile will remind you that About the next session that you wanted to see which is very helpful. I think because often you get lost in in some chitchat somewhere and This will remind you that you wanted to see a session You can share the session with other people and also Meanwhile, it it warns you when you wanted to see two sessions at the same time and so helps you to decide what you would like to see and Because of the time I'm not going more into detail of this. This is my basically my final app slide here Just to show some more stuff That is available in after all and I guess many people might like to use there are messengers of course multiple messengers and I Don't know if you know them. I guess telegram, you know, it's a Messaging network prior as well. The conversations is a client for Jabra XMPP The Twitter is for social media, but mainly for I mean The symbol says basically for Twitter. The master lab is the same as Twitter a but for for mastodon and I Have this PDF you were here because I was I was insulting a lot of PDF you was and still until I was happy And I thought I was happy with that new PDF viewer So I thought to put it here Also to show you there are also games in asteroid 2048 I guess many people know here Shattered pixel dungeon that's where I spend a lot of hours of my life and Yeah, so but I encourage you To look you for yourself. I just wanted to make some, you know, help you with the first steps or to share The the good apps I think are in there, but I encourage you to look for yourself get asteroid work play around I mean it's free software and It will it's in your hands and in your control and I hope that I could You know encourage you to do it There's one final thing before we can have some questions. I guess five minutes are left Now I talked a lot about asteroid and Now there's also G droid and I think it's just so fun because it shows you also how the free software world is working So G droid is basically a fork of asteroid that uses again the same Procedure It's just has a little bit other visual interface and Yeah, and then here I like this quote from the mafia who says Just use the asteroid to install G droid and it's basically everything you need to know about the concept of free software Yeah, I like this a lot. So thanks for listening and We have five minutes left You can either have questions or If you have an app that you think I missed to To show you and it's really cool and other people should know about I think that's also a very valuable Contribution here Can you hear me? I have a question because I was looking for notepad like Application on f droid that guy could for example write down shopping in and all of them seem a bit weird Do you have something right on what like shopping list for yourself or some notes when you're talking of somebody and you don't really feel like There is the tomboy pads for example on Debian systems that is very similar to that that you don't really care about it saved in a separate Location you don't care about it being in special place I just need for now notes and they will probably move to somewhere else later okay actually, I don't know I'm using I'm just using a simple txt file where I write down my notes and then That's all about my notes. So I I'm sorry. I cannot I don't know but I know from but if you pass by the Fsv assembly, I know that's Andre club and he has he's a big fan of some note That I don't know yet here, but if you are really looking for you can just ask Andre at the Fsv assembly, okay, we can also make audio notes and everything you can make Writing notes audio notes video notes. It's a very powerful app. I don't know if someone do I manage here or? Please Note apps that I really like for one omni notes Which you can do many different things with like text notes or lists and then the simple shopping list. It's just shopping lists Behind you. Thanks Who's responsible? For the identity of the guys who put APKs in asteroid. So who? Manages who gets to know Who puts the applications into asteroid and what is the process to identify malicious software? As I said in the beginning I'm a user and not a developer. I never did put any software into the repository So I'm not really sure How the process is but I have read the there are some There are some it does not only it has to be free software it also has to be you can have to compile it and be able to Use it only with free software here is someone who knows much more than me. I Hear can you get wait for the microphone, please? Hi, so basically we have a git repository or git lab where we put the beta data for the for the build and We clone the git repository of the application and have a built software to build it himself and then sign of himself And if you are a developer you can also do reproducible builds and sign it with your own key And we will verify the build and then upload the APK so it's all verified and open Where the APK is coming from? Thank you That's what I wanted to say to him I Will you publish a slide or at least the titles of them? Also, yes, I think in the wiki is I think in the wiki is possible, right? Yes, I will okay. I will upload them in the wiki in my talk So it's me. Oh, okay. Thanks for the talk But and just some things I figured out for a long long time took me a while to find it So my Recommendations would be add away, which is an app which blocks basically blocks every advertisement on your phone So very handy Of course key pass which is a manager passwords as a go-to and The app I really like is Wi-Fi key share So it basically gives you an QR code of the Wi-Fi password of every Wi-Fi locked in So you can share it with anyone who has a barcode reader So you can say well, we're somewhere else and you will be at my home later So you can share that moment without being in the Wi-Fi. So that makes things Easier mm-hmm. Cool. Thank you very much. That sounds very good Is it working? Oh, yeah, it's just a second. I'm sorry. This is just more note What's the question about whether the after it store is in the g-play store and it's not There's right now a fake after it store in there. So be careful Yeah, okay And where in the after a store? Yeah, no in the Google Play Store. I okay. It is called after it store and it's It's version number is 100,000 plus Like it's making the and is there a real version? No, there's not and there's also not a real version I thought yeah, that's what I thought. Yeah, please be aware as I said in the beginning There is no after it in the Google Play Store and don't don't download the the fake version please Yes, and it's also not in the Apple app store or whatever. It's called and you should download it on after it F dash draw it dot org. Yes, correct From someone where do the guy did here? Hopefully when we want to learn more about after it. So maybe once I answer my question before Where can I add any people here on the Congress? Who are doing development and where can I find them? Yeah, I know that but I'm a bit far away here are two developers. Yeah Just one more note About the transportation apps. I believe I believe you missed offy or a fee app which recently moved to after it because I Had a couple of hiccups with the Google Play Store. Is it free software? It is now okay, and I believe you talked about not wanting to do a PGP encryption with canine because you were afraid of losing a private key I Read I Haven't set it up myself yet, but I read that there is a possibility to generate another private key a sub key you could use and Just skip the rest of your key. So if you lose it, it's just that one sub key, true Maybe I just miss it if you're not religious about open software And you want to mix maybe most of after it stuff with some stuff from the Google Play Store Did you did you mention Yelp or is that a no-no? This what is Yelp store? Which enables you to pick some stuff that you only get at the closed source store and Which I like to use to mix and match, but that's a personal discussion By the way, I think Yes, I heard about it. Actually, I never used it, but and I always forget about it So there's a Yelp store Yelp store I think using the Yelp store you can get if I'm correct you can get all the apps from Google Play Store that for For no cost available Yeah, only those that are for no cost because else you need this payment system I Just don't forget because I don't I don't like to use any Binary blob on my phone. So this is no option for me but yes, I mean if you want to go the way from You know to get rid of Google and solar custom ROM without Google use asteroid and you really cannot like You really need this one or two apps or so then Yelp store might help you to access the Them from from the Google Play Store without having the need of a of a Google direct Google connection But generally I recommend to not use any binary blob on your phone and You can for for the things that you want and I really want to do except of marketing staff for Maybe some games or whatever the I think the things that you necessarily need to do are all available in after I also personally Only use after it on my phone But I feel a little bit excluded from communication communities like signal and I want to ask you whether I mean how you how you're handling it Are you solely having contacts with telegram for instance, which also has some security flaws? Maybe or I mean without no signal is easy you can install signal With a side load so you can download the APK from the web page You have a fingerprint to verify it's the There was no man in the middle and then you can do a side load install the APK and from then on Signal itself can update itself without yeah, so that's how I would I have two more apps one is all folks, you know it it's the Tor browser and the other one is all bot which roots your whole traffic through the Tor network and the third is AF wall plus I don't know if you know it. It's it's a fireball with which Stops blocks blocks the traffic from your mobile outside if you have I don't know Eps from the Google so also you can block the traffic or so in case they call home for example or yeah Okay And the all folks all bot and AF wall plus There is also one I would recommend that's called Wi-Fi privacy police Wi-Fi with the dash in the middle And it stops the Android from sending broadcasting Frames which actually gets tracked so if you're interested in this I gave a talk with a colleague yesterday About Wi-Fi tracking. It's called. It's actually in Germany, but it's called in German but it's called track me if you oh and There are lots of companies who do Wi-Fi tracking even even if you are not connected to an access point and just have your Wi-Fi enabled Wi-Fi privacy police Disables this by disabling every Wi-Fi that is not in your range currently so if you If you're interested in not getting getting tracked in the real world Look have a look at Wi-Fi privacy police So further questions. I just want to Save us that if anybody uses Google mail with Canine you cannot put your regular Google password in because Google will complain but you should create double authentication if you have Phone enabled together with email allows you to create tokens that you add to the app and you can create like thousands of them So that helps with non-Google phone because otherwise it's difficult to integrate Google services if you still have them even if you don't have Google on your phone and Maps me is very good with favorites Because you can collect places you've been to Good with what? Favorites that you can make a list of places you've been to and then it's they're very easy to access and very nice to place on the map so you can have tracking of places you visit often and Navigation between them you can well you can't do it about GPS, but you can basically get mapping easily for walking between them Remember correctly if I stopped using the Google Play Store, then I Aren't I am not able to use the Google notification server They have you Experienced downsides from this or is there how does fdroid come up with that that means the push notifications? Yes No, actually all my I've not no zero Google on it, and I don't know how it works, but I Get all the push notification. I mean sometimes they might Let's say I don't know Sometimes they are late, but that's really seldom Normally it works I Disabled every Google service on my phone a few months ago actually because I Have seen that the Google services access location information every few minutes and when I said disallow for this app my battery Dropped from one from two days to two hours and There is one thing where I'm missing the notifications and that's the Twitter app not the official app, but there is a I'm using one from the app store, and that's the thing. I miss it just checks every few minutes most of the other apps have some sort of Whatever it is web sockets or something and From my opinion it even needs less power than the Google push notifications with Which actually are there to save power? So I'm not sure more questions or Apps You want to have man you want to have mentioned Okay, so thank you very very much for your talk. Yeah, thank you very much for Also for the nice recommendations here
