VaultPony

VaultPony creates and opens encrypted containers on Android. A vault is a single encrypted file that holds a private filesystem, and only your password opens it. The containers are compatible with VeraCrypt, so you can open the same vaults on the desktop and back. There is no account, no cloud, and no network access. Your vaults are just files, kept wherever you choose. Features: * Create and open VeraCrypt-compatible containers, with a choice of cipher, hash (including Argon2id), and filesystem (FAT or exFAT). * Hidden volumes: conceal a second vault inside the first. Two passwords, and the outer one gives no sign the hidden one exists. The outer volume can be write-protected so normal use will not overwrite the hidden data. * Header backup and recovery, in-place password change, and keyfiles. * Biometric unlock, auto-lock when the app leaves the foreground, a hidden-screen mode that blocks screenshots, and a no-trace mode that remembers nothing. * Localized in English, German, Spanish, French, Russian, and Brazilian Portuguese, with live in-app switching. VaultPony is free and open source, built on a shared Rust core you can inspect. It is not affiliated with or endorsed by IDRIX; VeraCrypt is a registered trademark of IDRIX.
