Text Encryption/Decryption Supported algorithms: AES, DES, CAMELLIA, ChaCha20-Poly1305, XChaCha20-Poly1305, and Aegis256. Intuitive interface to enter text, choose an algorithm, and get the encrypted or decrypted result. Generate 256-bit Key Automatically Automatically generate random 256-bit keys in the Manage Keys section. Ideal for encrypting/decrypting without manually creating keys. Share/Import Encryption Keys via QR Share any key you’ve created so others can use the same encryption key. Export your key by pressing it in the list and choosing “Export.” Import a key using a QR code in “Import key via QR” under key management. File Encryption/Decryption Select files from your device. Encrypt or decrypt them using the same algorithms. The output file name is automatically labeled “.encrypted” or “.decrypted.” Built-In Key Manager :key: Add, delete, or generate random keys. Import keys from QR codes or export them as QR codes too. Keys are stored securely (using EncryptedSharedPreferences). Share Encryption Flow Use the Share action in other apps → choose “Encrypt” or “Decrypt” for text/files. Quick and convenient for multi-app workflows. Optional Accessibility Service :handshake: Detects selected text (when you highlight text on-screen). Detects copied text (clipboard). Displays a notification to encrypt/decrypt on the fly, opening the same activity (DialogFlowEncryptionActivity) with “Choose Operation.” Toggle Accessibility Logic A “BurbujaEncryption” button (or similar) enables/disables the logic internally without turning off the service in Android Settings. Perfect for pausing detection without leaving system settings. Dialog Flow (DialogFlowEncryptionActivity) :speech_balloon: A step-by-step sequence: “Choose Operation” (Encrypt/Decrypt) “Choose Cipher” “Pick/Enter Key” Final result Offers a guided, user-friendly experience. Android 13+ Support Requests POST_NOTIFICATIONS permission if you want to see notifications when text is selected or copied. Basic Usage :rocket: Main Screen Enter text and a key (or pick a saved key). Select the algorithm from the spinner. Tap Encrypt or Decrypt. Copy or share the resulting text. File Encryption :file_folder: Tap “FILE ENCRYPTION” on the main screen (MainActivity). Choose a file and an output folder. Pick the algorithm and a key. Tap EXECUTE. Accessibility (Optional) Enable it in Settings → Accessibility → “Encrypt-DecrypT Service.” Once enabled, selecting or copying text in any app triggers a notification. Tap it to open the DialogFlow (“Choose Operation”). In MainActivity, use “BurbujaEncryption” to enable or disable detection without turning the service off in Settings. Frequently Asked Questions (FAQ) :question: How do I enable/disable the accessibility service logic without going to system settings? Use the “BurbujaEncryption” button in MainActivity. It toggles an internal SharedPreferences flag. If disabled, the service won’t process events even if it’s still enabled in system settings. What if I forget my key? You won’t be able to decrypt your text/file. Make sure you keep a record of your keys or store them in the Key Manager. Why am I not seeing notifications when copying text? On Android 13+, you must grant the POST_NOTIFICATIONS permission. Check that the accessibility service is enabled and the internal logic is not toggled off.

Apps constantly request storage access; from basic media folders to full device control"All files access" permission, granting them unrestricted visibility into your device's storage.This creates a painful trade-off between functionality and privacy.SeekPrivacy eliminates that trade-off.Unlike a traditional vault, SeekPrivacy doesn't create a segregated safe-space;it actively cloaks and encrypts the files you designate as private. Even if a malicious app has full access to your storage, your protected files remain completely invisible and inaccessible to them.You maintain the ease of using your essential apps while enjoying complete security over your private data. Access your files normally, stay protected silently.What SeekPrivacy Does:Total App Blindness:Any app, no matter what level of storage access it has, will be unable to detect,read, or access your protected files.Seamless Access for You:You, the owner, can still open, view, and share these files normally.Deep Security:Because your files are encrypted, they are also protected from anyone gaining direct,physical access to your device's storage.What's New in SeekPrivacy v2.0Take full control of your private data with our new V2.0 File Management Suite. Organise your encrypted files into subfolders, find what you need instantly with integrated search, and manage your storage with built-in rename and move tools, all while maintaining military-grade encryption.

It stores GPS coordinates and sends them to your Web server so you can see where is the device. * You can build your own server (more privacy). * Send coordinates by Telegram (Bot) and SMS. * Settings from the website. * Control over time of activity and downtime to save battery. * Easy to create accounts without requesting personal data. * Timer for emergency. It's just a project, so it can only be used for experimental purposes and not for security purposes.

Shelter is a Free and Open-Source (FOSS) app that leverages the "Work Profile" feature of Android to provide an isolated space that you can install or clone apps into. For a full description, please read from the Git repository of Shelter. A summary is provided below. The main use-cases of Shelter include: - Installing apps inside a work profile for isolation - "Freeze" apps inside the work profile to prevent them from running or being woken up when you are not actively using them - Installing two copies of the same app on the same device Note that Shelter depends on the Work Profile feature of the Android system, so any bugs related to Work Profiles in the Android-derived system you are using will affect Shelter. In addition, Shelter can only be as secure as the Work Profile implementation.

Sigil is an open-source, advanced encryption utility built for defense-in-depth and memory safety. Unlike standard tools that rely on a single algorithm, Sigil employs a multi-layered, configurable architecture to ensure your data remains secure against sophisticated cryptanalysis.The application operates entirely offline, performing all cryptographic operations locally on your device with a modern Material 3 interface that balances high-level security with usability.Core Security FeaturesEncryption Profiles: Customize your security posture. Switch between "Standard AES-GCM" (Raw mode) for compatibility with external tools, or the "Sigil Chain" for maximum defense.Multi-Layer Cascade: The default Sigil Chain wraps your data in a hybrid cascade of XChaCha20-Poly1305 + Serpent-CBC + Twofish-CBC + AES-256-GCM. This defense-in-depth approach ensures that even if one algorithm is compromised, your data remains protected by independent layers.Zero-Knowledge Auth: Secure the app with a numeric PIN or a strong alphanumeric Password. Credentials are hashed using Salted Argon2id and never stored in a reversible format.Hardware-Backed Vault: When supported by the device, master keys are generated and stored in the Android Keystore (or StrongBox). Saved encryption passwords never touch the disk in plaintext.Memory Hygiene: Sensitive data buffers are zeroed where possible after use to reduce exposure to memory dumps.Privacy & System HardeningScreen Security: Prevents screenshots and hides app content in the "Recent Apps" overview using FLAG_SECURE, protecting against visual snooping and malicious screen recorders.Clipboard Protection: Automatic wipe timers and Android 13+ sensitive content flags prevent clipboard managers from retaining your decrypted data.Offline-Only: Sigil does not request the INTERNET permission. It tracks no analytics, collects no telemetry, and stores no data on external servers.Advanced User ToolkitSecure Keystore: Save, view, and manage encryption keys using the hardware-backed vault.Custom Encryption Control: Full manual control over encryption chains. Build your own cascade from 18 algorithms, reorder layers, and toggle ZLib compression.System Console: Real-time logging of the encryption process, providing precise timing metrics and error diagnostics.Advanced Theming: Material You Dynamic Colors, Dark/Light modes, and a custom HSV color engine.Technical SpecificationsKey Derivation: Argon2id (Configurable up to 256MB RAM) + SHA-512 pre-hashing.Supported Algorithms: AES-256-GCM, AES-256-CBC, ChaCha20-Poly1305, XChaCha20-Poly1305, ARIA-256-GCM, Twofish, Serpent, Camellia, CAST6, RC6, SM4, GOST, SEED, Blowfish, IDEA, CAST5, TEA, and XTEA.Open-Source TransparencyThe complete source code is available for public audit on GitHub: https://github.com/Animesh-Varma/SigilFor the complete release roadmap and planned features, please visit: https://github.com/Animesh-Varma/Sigil/releasesFor any queries, please contact: sigil@animeshvarma.dev

This app does not claim any permissions, so you can trust that it cannot send any of your private data to anyone. Messages produced by this app are secure and, for example, can be confidently sent over a network. It uses AES in GCM mode with no padding for encryption. It uses Argon2 and a random Salt to derive a secure key from the entered passphrase. This is a very powerful encryption. It also encrypts its settings before storing them on the device. However, the app might be vulnerable to some attacks. Although it is secure enough to stand attacks from non-expert crackers, e.g. normal users, should not be used for serious data encryption. Upgrading from 4.x to 5.x The encryption of the settings is changed. The app should be able to detect the old settings and upgrade them with the new encryption algorithm. However, it's a good idea to back-up your passphrase. (Well, it's generally a good idea to back-up encryption keys and passwords in a secure place). If the app didn't work after upgrade, uninstall and install it again.

Skewy has two objectives: 1) By pressing Play, Skewy's sound will mask your conversation / will make the data picked up by the microphone unusable (like a jammer). Giving someone who wants to use this data a near impossible task to filter out what you said. The Sound Tab allows for fine tuning of the sound level and set an optional alarm to notify when masking no longer occurs. 2) Skewy processes the data to identify ultrasonic (inaudible) signals. Such signals are used by advertisement/tracking companies such as SilverPush to access your phone without you noticing. Skewy can notify you when such a signal is present and optionally jam such a signal, if the frequency shield is turned on. All data is visualized with live graphs (both sound and frequency). It works best with a small hardware extension (a small speaker/headphone) to focus the sound on the mic, making it silent its surroundings. An idea how to build it is found in the Menu. No actual sound data is saved.
