Secure QR Share lets you send passwords, PINs, and sensitive text to someone nearby without typing, screenshots, or cloud services — just a QR code. HOW IT WORKS 1. Sender enters text or a password and chooses a shared PIN. 2. The app encrypts the payload with AES-256 and displays a QR code. 3. Receiver scans the code with Secure QR Share, enters the same PIN, and the original text is instantly decrypted and copied to the clipboard. FEATURES • AES-256-CBC encryption with PIN-derived keys — no server, no cloud • Works fully offline — no internet permission required at runtime • Share sheet integration — highlight text anywhere and share directly into the app • App Links support — QR codes can be opened from the camera or browser • Optional unencrypted mode for non-sensitive public links • No ads, no tracking, no analytics, no accounts PRIVACY Secure QR Share never transmits your data. Everything is processed locally on your device. The encryption key is derived from your PIN and never stored or sent anywhere. OPEN SOURCE The full source code is available on GitHub under the MIT license.

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.

Standard vaults create a clunky "island." SeekPrivacy creates a shield. Apps like social media and basic tools demand "Storage Access"if you refuse, they break. If you accept, they spy. This creates a painful trade-off between functionality and privacy.SeekPrivacy is built on the principle that your phone's operating system and other apps should be considered "hostile territory." It assumes the Android OS is compromised and every other app is a potential spy. Its architecture ensures that even if a malicious app gains full control of the device, your data remains a cryptographic black box.SeekPrivacy eliminates this blackmail. It provides multi-layered defense by isolating data within an encrypted sandbox, inaccessible to other apps, the OS, or unauthorized physical extraction—providing activist-grade security. Built on the belief "Privacy Without the Tradeoff of Ease", even if a malicious app has full device control, it sees nothing.

You will need https://f-droid.org/packages/com.google.zxing.client.android to be installed to use this. First visit https://send-to-computer.appspot.com on your computer and make sure popup blocking is disabled. Scan the barcode given on the screen (the app remembers the unique id at the end of the url so that it can identify your requests for web pages). Choose Open in Browser and choose Send to Computer (you may have to scroll). You are now setup and can send webpages to your computer via the browser share menu. The computer browser checks every two minutes for requests so you might have to wait a little. The source code is also available for the server side of things.

This adds an item to the share menu to save the object to the sdcard. For example, let's say you place a memory card in the phone to look at some pictures. You look at them in the gallery and as you go you copy the good ones to the internal memory. Not all things will be saved as expected: a webpage will only have it's url saved.
