Calculator Lock - Photo Vault
What Calculator Lock - Photo Vault is
Calculator Lock - Photo Vault is an Android app that conceals a privacy vault behind a working calculator and opens it with a 4-digit PIN. It stores photos, videos, audio, PDFs, files, and Secure Notes in encrypted app-private storage on the device. Different PINs can open separate vaults without a visible session switcher. Users can search and pin notes, organize items with built-in folders, and restore deleted media or notes from Trash. Photos, videos, audio, and PDFs can be viewed in the app; other files can be unlocked, exported, or shared if previews are unsupported. The maker describes screenshot protection and clipboard cleanup for sensitive flows. The free plan allows up to two personal vaults, and ads may appear. There is no cloud backup or PIN recovery, so content may be lost if the PIN, app data, or device is lost. Optional Intruder Detection may take a front-camera photo after repeated failed PIN attempts and requires camera permission and applicable premium access.
