LockMyPix vs Valv

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.

Valv is a free Android gallery vault for storing photos, GIFs, videos, and text files in encrypted form on a device. Files can be arranged into folders, with notes or text attached, and separate vaults can use different passwords. Access supports a password or PIN; one vault can also be unlocked with fingerprint or face authentication. Valv uses ChaCha20 encryption and derives keys with PBKDF2 and HMAC-SHA512. PBKDF2 uses 50,000 iterations by default, and that count can be changed. Encrypted files remain on local storage, supporting backups and transfers between devices, but cloud backup is not available. The project README says the app requires no permissions, while Google Play declares no data collected and no data shared with third parties. Valv requires Android 9.0 or newer and is listed at free. It is distributed through Google Play, F-Droid, and a GitHub APK, under GPL-3.0-only.
