Calculator Lock - Photo Vault vs Safety Photo+Video

Calculator Lock - Photo Vault is an Android privacy vault concealed behind a working calculator and opened with a 4-digit PIN. It stores photos, videos, audio, PDFs, files, and Secure Notes in encrypted app-private storage. Different PINs can open separate vaults without a visible session switcher. Users can search and pin encrypted notes, organize items in built-in folders, and restore deleted media or notes from Trash. The app displays photos, videos, audio, and PDF previews; unsupported files can be unlocked, exported, or shared. The maker describes screenshot protection and clipboard cleanup on sensitive flows. The free plan costs nothing and allows up to two personal vaults, with ads possibly appearing. There is no cloud backup or PIN recovery. Optional Intruder Detection may capture a front-camera photo after repeated failed attempts.

Safety Photo+Video is a mobile vault for keeping selected personal photos and videos apart from the everyday gallery. It runs on Android and iOS; the App Store listing requires iOS 15.0 or later, and downloads are available for iPhone, iPad, and Google Play. Users can arrange media in albums, mark favorites, assign separate passwords to albums, and capture new photos or videos inside the vault. Access uses a passcode or supported biometric method, depending on the device and app version. A different password can open a decoy vault. Files can move through a browser on the local Wi-Fi network. With zero-knowledge backup enabled, media is encrypted before upload and needs user-controlled credentials or recovery information. The free plan includes 10 GB. Options include 2.99 USD monthly iCloud Sync, 4.99 USD once for Pro, and storage plans up to 200 GB. Expired cloud backup is retained for 90 days, and private media is not used for AI training.
