## Description
Keep your private photos, videos, and files truly private. Calculus Lock looks and works like an ordinary calculator — but enter your secret PIN and it unlocks a hidden, secure vault that only you can open.
A SECRET HIDDEN IN PLAIN SIGHT
The app on your home screen is a fully functional calculator. Anyone who opens it just sees a calculator. Type your private passcode and the real Calculus Lock appears — your personal vault for everything you'd rather keep to yourself.
WHY PEOPLE TRUST CALCULUS LOCK
• Calculator disguise — no obvious "locked app" icon to invite curiosity
• PIN + biometric unlock — secure with Face ID, Touch ID, or fingerprint
• Private photo & video vault — import from your gallery or capture directly inside the app
• Hide any file — documents, screenshots, and more, all in one secure place
• Intruder alerts — silently capture a photo after failed unlock attempts
• Decoy PIN — open a separate, harmless vault under pressure
• Screenshot protection — stop your private content from being captured
• Recycle bin — recover items you delete by mistake
• PIN recovery — get back in with security questions or a recovery code
100% PRIVATE BY DESIGN
Your data never leaves your device. There are no accounts, no cloud uploads, and no servers that can see your content. Your PIN is stored only as a secure one-way hash — not even we can access your vault. What's yours stays yours.
