LockMyPix vs NullVault

LockMyPix is a mobile vault for photos, videos, documents, and other files on Android and iOS. The maker says imported files are encrypted with AES CTR in real time and kept on the device or an SD card rather than sent to its servers. For backup, LockMyPix Cloud can transfer files to the user's Google Drive or Dropbox account. Access can be protected with a password, PIN, pattern, fingerprint, or face unlock; face unlock depends on the device. The vault supports unlimited videos, including 8K video, and unlimited folders and subfolders. Premium features include a decoy vault, app disguise, intruder selfies, and SD-card storage. Free Basic Protection costs nothing, includes ads, and leaves some features to Premium. LockMyPix Premium costs $29.99, paid once and removes ads while unlocking premium features. The iOS listing requires iOS 15 or later; Mac support is listed for macOS 12 or later on an Apple M1 chip or later.

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.
