What Calculator Lock - Photo Vault is
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 on the device. Separate PINs can open different vaults without a visible session switcher. Users can search and pin encrypted notes, organize content in built-in folders, and restore deleted items from Trash. Photos, videos, and audio can be viewed in the app, and PDFs have previews; other files can be unlocked, exported, or shared when preview is unsupported. The maker describes screenshot protection and clipboard cleanup on sensitive flows. The free plan supports up to two personal vaults, and ads may appear. There is no cloud backup or PIN recovery, so content may be lost if a PIN is forgotten or app data or the device is lost. Optional Intruder Detection may capture a front-camera photo after repeated failed PIN attempts and requires camera permission and applicable premium access.
