CalcSafe vs LockMyPix

CalcSafe is a mobile app that presents a private file vault behind a working calculator. Entering a secret PIN in the calculator opens the vault. The app stores photos, videos, documents, audio files and passwords. Photos and videos imported from the gallery disappear from the camera roll and remain locked inside the vault. CalcSafe says stored files are encrypted and secured on the device, with no cloud storage, servers or uploads. Setup requires no account, and the calculator disguise can be customized with themes and colors. The listed feature set also includes a decoy vault and intruder alerts. CalcSafe provides download links for both Android and iOS and links to a Help Center and Contact page. Its Free plan costs nothing and includes all core features free forever, with no account needed.

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.
