Description by Madlab Studios(from Google Play)
Invisible Ink is the ultimate privacy tool for concealing your secrets. Hide any file (PDF, Audio, Text) or secret message inside an innocent-looking image using advanced steganography and military-grade encryption.
🔒 Key Features:
Hide Any File: Embed PDFs, audio recordings, or documents directly into PNG/JPG images. Encrypted Text: Send secret messages that can only be read with the correct password. AES-256 Security: All data is encrypted with military-grade AES-256 encryption using PBKDF2 key derivation. Without the password, your secrets are impossible to access. Total Privacy (Offline): No cloud, no servers. All processing happens 100% locally on your device. Your data never leaves your phone.
🕵️♂️ How it works:
Hide: Select a cover image, choose your secret file or text, set a password, and "Process". The result is a standard image file that looks normal to everyone else. Share: Send the image via Email, Telegram, or save it to your documents. Reveal: Open the image in Invisible Ink, enter the password, and instantly retrieve your hidden data. ⚠️ Note on Sharing: To preserve the hidden data, always share images as "Files" or "Documents" (e.g., via Email or Telegram File). Avoid apps that compress images (like WhatsApp or Messenger standard photo sharing), as compression will destroy the hidden encrypted data.
