Calculator Lock - Photo Vault
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.
