Mullvad VPN: privacy is a universal right
APK
Free the internet from data collection with Mullvad VPN – a service that helps keep your online activity, identity, and location private. Only €5/month. Get started 1. Install the app. 2. Create an account. 3. Add time to your account via our website or vouchers. To make sure to block third-party cookies and other tracking technologies – use Mullvad VPN together with Mullvad Browser (free of charge). ANONYMOUS ACCOUNTS – NO ACTIVITY LOGS • Creating an account requires no personal info - not even an email address. • We keep no activity logs. • We offer the possibility to pay anonymously with cash or cryptocurrency. • Bypass geographical restrictions with our global network of VPN servers. • Our app uses WireGuard, a superior VPN protocol that connects fast and doesn’t drain your battery. HOW DOES MULLVAD VPN WORK? With Mullvad VPN, your traffic travels through an encrypted tunnel to one of our VPN servers and then onward to the website you are visiting. In this way, websites will only see our server’s identity instead of yours. Same goes for your ISP (internet service provider); they’ll see that you’re connected to Mullvad, but not your activity. It also means that all the third-party actors with technology integrated into the various websites you visit can’t sniff out your IP address and use it to track you from one site to another. Using a trustworthy VPN is a great first step to reclaim your privacy online. In combination with Mullvad Browser you make sure to block third-party cookies and other tracking technologies. FREE THE INTERNET FROM MASS SURVEILLANCE AND DATA COLLECTION A free and open society is a society where people have the right to privacy. That’s why we fight for a free internet. Free from mass surveillance and censorship. Free from big data markets where your personal information is up for sale. Free from authorities mass monitoring every click you make. Free from an infrastructure mapping your whole life. Mullvad VPN and Mullvad Browser is our contribution to the fight. TELEMETRY AND CRASH REPORTS The app collects a very minimal amount of telemetry, and it does not in any way tie it to an account number, IP or other identifiable information. Account numbers are used for authentication. App logs are never sent automatically but are rather explicitly sent by the user. App version checks are performed every 24 hours to tell the app if there are any upgrades available and if the currently running version is still supported. If the split tunneling feature is used, then the app queries your system for a list of all installed applications. This list is only retrieved in the split tunneling view. The list of installed applications is never sent from the device.

Nearby Glasses
APK
This app attempts to detect smart glasses nearby and warn you.⚠WARNING!⚠HARASSING someone because you think they are wearing a covert surveillance device can be a criminal offence. It may even be a more serious offence than using such a device. Please seek legal advise regarding your local laws on this matter.⚠DO NOT HARASS ANYONE AT ALL⚠This app has one sole purpose: Look for smart glasses nearby and warn you.This app notifies you when smart glasses are nearby. It uses company identificators in the Bluetooth LE data sent out by these. Therefore, there likely are false positives (e.g. from VR headsets). Hence, please proceed with caution when approaching a person nearby wearing glasses. They might just be regular glasses, despite this app’s warning.The app’s author takes no liability whatsoever for this app nor it’s functionality. Use at your own risk. By technical design, detecting Bluetooth LE devices might sometimes just not work as expected.False positives are likely. This means, the app Nearby Glasses may notify you of smart glasses nearby when there might be in fact a VR headset of the same manufacturer or another product of that company’s breed. It may also miss smart glasses nearby.However, this app is free and open source, you may review the code, change it and reuse it (under the AGPL3 license).Nearby Glasses does not store any details about you or collects any information about you or your phone. There are no telemetry, no ads, and no other nuisance.If you choose to store (export) the logfile, that is completely up to you and your liability where this data go to. The logs are recorded only locally and not automatically shared with anyone. They do contain little sensitive data; in fact, only the manufacturer ID codes of BLE devices encountered.Use with extreme caution! As stated before: There is no guarantee that detected smart glasses are really nearby. It might be another device looking technically (on the BLE adv level) similar to smart glasses.Please do not act rashly. Think before you act upon any messages (not only from this app).Why?Because I consider smart glasses an intolerable intrusion, consent neglecting, horrible piece of tech that is already used for making various and tons of equally truely disgusting 'content'.Some smart glasses feature small LED signifying a recording is going on. But this is easily disabled, whilst manufacturers claim to prevent that and take no responsibility at all (tech tends to do that for decades now).Smart glasses have been used for instant facial recognition before and reportedly will be out of the box. This puts a lot of people in danger.How?It's a simple rather heuristic approach. Our approach comes from the Bluetooth SIG assigned numbers repo. Following this, the manufacturer company's name shows up as number codes in the packet advertising header (ADV) of BLE beacons. They are immutable and mandatory. Of course, Meta and other manufacturers also have other products that come with Bluetooth and therefore their ID, e.g. VR Headsets. Therefore, using these company ID codes for the app's scanning process is prone to false positives. But if you can't see someone wearing an Occulus Rift around you and there are no buildings where they could hide, chances are good that it's smart glasses instead.According to the Bluetooth SIG assigned numbers repo, we may use these company IDs:0x01AB for Meta Platforms, Inc. (formerly Facebook)0x058E for Meta Platforms Technologies, LLC0x0D53 for Luxottica Group S.p.A (manufactures the Meta Ray-Bans)0x03C2 for Snapchat, Inc., that makes SNAP SpectaclesI hope this is useful for someone.

OONI Probe
APK
Are websites and social media apps blocked? Is your network unusually slow? Run OONI Probe to find out! With this app, you will examine the blocking of websites and instant messaging apps, measure your network's speed and performance, and check whether systems that could be responsible for censorship and surveillance are in your network. OONI Probe is developed by the Open Observatory of Network Interference (OONI), a free software project (under The Tor Project) that aims to uncover internet censorship around the world. Since 2012, OONI’s global community has collected millions of network measurements from more than 200 countries, shedding light on multiple cases of network interference. ▶ Collect evidence of internet censorship You can check whether and how websites and instant messaging apps are blocked. The network measurement data you will collect may serve as evidence of internet censorship. ▶ Detect systems responsible for censorship and surveillance OONI Probe tests are also designed to uncover the presence of systems (middleboxes) that could be responsible for censorship and surveillance. ▶ Measure the speed and performance of your network You can measure the speed and performance of your network by running OONI's implementation of the Network Diagnostic Test (NDT). You can also measure video streaming performance with the Dynamic Adaptive Streaming over HTTP (DASH) test. ▶ Open data OONI publishes network measurement data because open data allows third parties to verify OONI findings, conduct independent studies, and answer other research questions. Openly publishing OONI data also helps increase transparency of internet censorship around the world. You can explore and download OONI data here: https://ooni.io/data/ ▶ Free software All OONI Probe tests (including our NDT and DASH implementations), are based on free and open source software. You can find OONI software projects on GitHub: https://github.com/ooni. Curious to learn how OONI Probe tests work?
