Calculator: Secure Photo Vault

Calculator: Secure Photo Vault is a fully functional calculator with a private, encrypted vault for sensitive files. The calculator is real and usable on its own; the private-vault features are clearly disclosed here in the Play listing. PROTECT WHAT MATTERS Keep personal content in encrypted on-device storage. Add photos and other supported files, then access them with the PIN you set up. Your files are encrypted at rest with AES-256-GCM using Android Keystore protection when available. They are not uploaded to a cloud account, and this app has no ads or analytics. PRIVATE VAULT FEATURES • Protect photos, videos, text notes, voice notes, and PDFs • Browse protected files in a private library • View photos, play videos, read notes, and open PDFs inside the app • Import content from your device and capture photos directly when you choose • Keep decrypted video and PDF content in the app rather than writing a plain copy to storage • Use a PIN to unlock the private area • Keep a working calculator available from the launcher YOUR DATA STAYS WITH YOU There is no account, no advertising SDK, no analytics, and no cloud upload. Your files remain on your device unless you deliberately export or share them. Camera, microphone, and biometric permissions are optional and requested only for the features you choose to use. FREE AND PRO The free app lets you protect up to 50 items in encrypted local storage. Vault Pro is an optional one-time purchase—never a subscription. It unlocks unlimited encrypted storage, albums and folders, biometric unlock, a decoy PIN, face-down auto-lock, encrypted voice notes, self-destruct timers, media filters, and selective file export with optional metadata. It also adds password-encrypted shareable note tokens and encrypted backup and restore. SECURITY FEATURES YOU CONTROL Use biometric unlock on supported devices, or keep using your PIN. A decoy PIN can open a separate empty private area while your real content remains encrypted. You can also enable auto-lock when leaving the app or place your phone face-down to lock it quickly. For files you choose to share or export, Calculator: Secure Photo Vault shows where they are going. Exported copies are no longer protected by the vault, so choose a destination you trust. Calculator: Secure Photo Vault is designed for adults who want practical, local protection for personal files without accounts, ads, or cloud storage.
