NullVault
nullvault.app
What it is
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.
