NullVault vs Vaulty

NullVault stores photos, videos, files, and notes in separate encrypted vaults, each opened with its own pattern. Entering a pattern opens the matching vault without showing a master list or the number of vaults. Within a vault, users can organize content into collections, search, and sort; they can capture or import items and deliberately export selected ones. Exported copies are outside NullVault’s protection.

Local vaults work offline without a NullVault account or server. The maker describes Android encryption using AES-256-GCM, Argon2id, and Android Keystore material; its iOS description lists AES-256-GCM, Argon2id, Apple CryptoKit, and libsodium. iOS supports encrypted iCloud backup and controlled read-only sharing through CloudKit, while Android supports portable encrypted backups. The free iOS plan allows up to five vaults and 20 items total, with one collection per vault. Compatibility is listed for iPhone running iOS 26 or later and Android phones running Android 10 or later. The maker warns that a compromised device may expose patterns, keys, screens, or plaintext, and that hidden vaults do not make encrypted data impossible to detect.

Vaulty is an Android private gallery for keeping photos and videos behind a PIN or password. Separate, custom-named vaults let users divide media or share access selectively. Files can be hidden from the device gallery, including in batches, then arranged into albums and viewed with an in-app player, zoom, or slideshow. An incorrect password can trigger a front-camera photo. Vaulty offers automatic backup to the user’s own Google Drive and can restore media after a device switch or reset; backups are kept in Google Drive rather than Vaulty’s servers. Its privacy policy says the app cannot access concealed content, while Google Drive backups follow Google’s terms and privacy policy. The policy also notes collection of device and operating-system details, IP-based general location, and information supplied to support. The free plan costs nothing and includes ads and automatic Google Drive backup.
