Calculator Lock is a privacy vault disguised as a working calculator.
Create separate private vaults with unique PINs for photos, videos, audio, and documents. To access your vault, long-press the 5 key on the calculator and enter your 4-digit PIN.
HOW IT WORKS
The app opens as a normal, working calculator. Without the correct PIN, it stays a calculator. Inside the vault, you can import from Gallery or Files, browse content by type, organize items with albums, and keep deleted files in Trash before permanent removal.
