SOS Ring forces your phone to ring at full volume when you receive a call from a VIP contact, even if your phone is in Silent, Vibrate, or Do Not Disturb mode. Perfect for families where someone always keeps their phone on silent but needs to be reachable in emergencies. HOW IT WORKS: • Add your VIP contacts (family, partner, etc.) • Enable the monitoring service • When a VIP contact calls, SOS Ring overrides Silent/DND mode, plays the ringtone at your chosen volume (50-100%), and vibrates • After the call ends (answered, missed, or rejected), your phone is restored to its original state — silent mode, DND, volumes, everything WHY THIS APP EXISTS: Android 14+ removed per-contact DND exceptions. No built-in way exists to let specific contacts bypass silent mode. Google restricts READ_CALL_LOG on the Play Store, so this type of app can't be published there. SOS Ring is free, open source, and works where others can't. FEATURES: • Pick VIP contacts from your phonebook or enter manually • Configurable override volume (50-100%) • Works in Silent, Vibrate, AND Do Not Disturb mode • Full state restore after call (including alarm volume) • Survives phone reboots (auto-start) • Minimal battery usage (event-driven, no polling) • Dark mode support • No ads or tracking LOCATION SHARING (optional, peer-to-peer): • No SOS Ring server required — you pick a UnifiedPush distributor app (e.g. ntfy on F-Droid); it relays only encrypted data • End-to-end encrypted using Web Push encryption; the distributor never sees your location • Each message is signed with a per-device key in the Android Keystore, so the recipient can verify the sender • Pairing is explicit via QR code — no automatic connections • Location sharing is off by default per contact; you control who can see your location • Live tracking streams your position roughly every 10 seconds for a chosen duration, shown on an OpenStreetMap map in the app • Tracked path is saved locally on the requester's device only — no data leaves without your explicit action • No server, no analytics, no tracking PERMISSIONS EXPLAINED: • Phone State & Call Log: detect incoming calls and identify the caller • Contacts: pick VIP contacts from your phonebook • Do Not Disturb access: override DND when a VIP calls • Notifications: show a small persistent notification while monitoring • Location (including background): used only to answer location requests from paired contacts you explicitly authorized, even while the app is not on screen; nothing is collected or sent otherwise SOURCE CODE: https://github.com/JackRushante/SOSRing

This app is an implementation for SQRL (Secure Quick Reliable Login) on Android. Before you begin using SQRL to login to websites, your SQRL private identity must be created. You only need one, probably for life, because it reveals NOTHING about you, and it's highly secure. It's just a very long (77-digit) random number. From then on, whenever you login with SQRL to a website, your private identity is used to generate another 77-digit number for that one website. Every website you visit sees you as a different number, yet every time you return to the same site, that site's unique number is regenerated. This allows you to be uniquely and permanently identified, yet completely anonymous. Since you never need to use an eMail address or a password, you never give a website your actual identity to protect. If the website's SQRL identities are ever stolen, not only would the stolen identities only be valid for that one website, but SQRL's cryptography prevents impersonation using stolen identities. This is as good as it sounds. It's what we've been waiting for.

By default Android can't handle SVG files, when you try to open them from a file manager. A Browser could handle SVG, but the most of them don't allow to call SVG files from a file manager. SVG redirect makes that possible.

As a minimalistic workout tracker SWJ is designed for those who know what they want and who are concentrated on results. You will not find predefined description for routines or any other amateur targeted features here.

Saber is the notes app built for handwriting. It's designed to be as simple and intuitive as possible, while still delivering unique features that you'll actually use. Additionally, Saber is available across all your devices, large and small, and syncs between them seamlessly. Notably, it can invert your notes when you're in dark mode. This allows you to write with white ink on a black background, which is much easier on the eyes in low-light environments like when the teacher turns off the lights in class. Images and PDFs are also inverted, so you can still use a digital printout or a textbook without the fuss. Saber uses a dual-password system to protect your notes from anyone but you, even if they have complete control over the server. You can safely store your notes on the official Saber server, another server, or even host your own! The app is completely open-source so that anyone can view the source code and see exactly what it's doing and how it handles your data. Many other note-taking apps are closed-source and proprietary, meaning that their inner workings are a mystery to the public. As someone who studies maths, highlighting multi-line equations was always a hassle with other apps, where the highlighter would change color when it overlapped with itself. Another problem I had was that in some apps, the highlighter would render on top of the text, fading it out and making it hard to read. Saber's highlighter has no such issues. It utilizes canvas compositing to render the highlighter in a way that is consistent with/better than traditional paper, where it handles overlaps and maintains color consistency. Saber has everything you need to keep your notes organized. Create folders inside folders inside folders to your heart's content with no limit on the number of nested folders. And even though a note may be buried deep within a nested folder, you can still access it easily with your most recent notes always available on the home screen. Discover a whole new way to capture and organize your thoughts with Saber. Whether you're a student, professional, or creative mind, Saber is your trusted companion for digital handwriting.

Safe Charger is a simple app to maintain healthy battery life. It has been advised by some technology experts that the phone should not be charged to a complete charge cycle repeatedly in order to maintain a good battery life. Also, this is just a small idea which emerged when I heard the shocking news of my friend’s phone exploded near his head after a complete charge. Fortunately, nothing happened to him.The following is the working of the application:The application will be always idleWhen the android phone goes to the charging state, a background thread will be fired which checks the battery level in an optimized way.The application will trigger a notification sound when the charge reaches 85%.

★ Safe Notes is an open-source project that aims to provide an encrypted, private note manager. ★ Employs rigorously tested AES-256 encryption standards to encrypt your notes. ★ Incognito Keyboard ★ Brute-force protection ★ Protection against data snooping via adb ★ Android background snapshot protection ★ Inactivity guard ★ Automated encrypted backup ★ Arctic Nord style dark and light theme ★ Customization for colorful notes ★ Seamless migration to new device. Use the backup to move your data from one device to another device. ★ Safe Notes provides ultimate security - you don't have to trust us, or any other third party because everything is done locally on your phone. ★ Contrary to the ongoing frenzy of "move everything to cloud" we believe in "localization of user data" giving you the control of your data and not some third-party cloud service provider. ★ Completely anonymous, no inbound and outbound requests. --- How it works --- ★ Safe Notes encrypt each note with a unique AES-256 symmetric key derived from your passphrase and randomly generated salt. ★ If an attacker tries to brute-force your encrypted notes it will take "Trillions Upon Trillions years" in contrast, the universe has only existed for 15 billion years. (You must use strong and long passphrase). ★ AES-256 is symmetric key encryption that is quantum-resistant, i.e. it isn't vulnerable to quantum computers. ★ Everything is stored locally on the user's device. ★ Your passphrase is never stored on the device, it gets purged as soon as you exit the app. ★ We can't decrypt your notes even if we wanted to. That gives you the ultimate security, but it also means that a lost passphrase can never be recovered. ★ Safe Notes is an open-source, not-for-profit project.

Safe space is an app that creates a separate place on your android device to store valuable files. This storage location is not visible to other apps and is encrypted by the system by default. Features: * Store files in a secure storage location that is not visible to other apps and is secured by device encryption and system authentication (Biometric and PIN/Pattern/Password) * Open Images, Audio, Video, PDF documents and plain text documents * Create simple text notes without leaving the app * Dark and light mode * ability to copy and move files * Import from and export files to external storage without storage permissions * Completely offline with no telemetry and data collection

Do you feel envious about the new iOS 14's privacy feature that shows a dot indicator whenever CAMERA or MICROPHONE is accessed? Safe Dots adds the same iOS 14 style indicators (few pixels light up as a dot) to the top right (default) corner of your screen whenever any third-party app or service uses your phone's camera or microphone. Safe Dots will be visible even on your lock screen. Configuring the App is as simple as enabling the Safe Dots Accessibility Service (Toggle switch in the App › (More) Downloaded Services/Installed Services › Dot › Enable). By default, the App is configured to show iOS 14 style colored access dots - green for camera access, orange for microphone access. The App itself does not request for the camera or microphone access so, don't worry!. The app displays Safe Dots whenever the phone's camera or microphone is engaged by a third-party App. Maintain an Access Log, which can be accessed from the App's main settings screen. The Access Log shows when the camera/microphone was accessed, which App was in the foreground at the time of access initiation and how long did the access last.

This app allows you to generate site-specific password from a single master password. This avoids the hassle of remembering a unique password for each website you sign up to. We all have dozens (or even hundreds) of website accounts we have to remember. We are then tempted to reuse the same password for several websites. If one of them is hacked or malevolent, you risk exposing your other accounts. It mixes together your personal master password and the website domain using a little cryptographic magic we call SHA-1. It will always get the same result if given that domain name and master password, but will never get that result if either changes. (Well, once in a few billion times it might.)

The app can use GPS to find your location, although you can enter geographic coordinates. It calculates prayer times, gives notifications and has a Qibla for showing the direction of Mecca.
