Valv is an encrypted gallery vault designed to protect private files on Android devices. It allows users to securely store images, animated GIFs, videos, and text documents within password-protected vaults. Files are encrypted using ChaCha20, with encryption keys derived through PBKDF2 and HMAC-SHA512. Users can organize their collections into folders for easier navigation. Multiple vaults can be created using different passwords, allowing separate collections to remain independently accessible. Encrypted files are stored directly on the device, making backups and transfers between devices straightforward. Additional functionality includes attaching notes to files and switching between light and dark themes. Valv supports Android 9 and newer without requiring application permissions.
