About Lock It: Calculator Vault
Lock It: Calculator Vault is a calculator that does real math. Type your own secret equation and press =, and it opens a private vault instead. Inside you can keep photos and videos, notes, passwords and 2FA codes, encrypted with AES-256 on your phone. You can also message and make live video or voice calls with people you invite by key or QR code, and send files up to 1 GB through Encrypted Cloud. Your equation is stored only as a salted hash, so we can't see it. Free with ads; optional Premium Pro and Offline Vault upgrades are available inside the app. Android only.

Why Lock It: Calculator Vault
01 · The problem
People need a private place on their phone for sensitive notes, passwords, media and conversations that isn't obvious to anyone who picks up the device.
02 · The solution
Lock It shows a working calculator and unlocks a vault only when a secret equation is entered, holding encrypted notes, keys, media and optional private messages and calls.
03 · What makes it different
The calculator is a genuine working calculator rather than a decoy screen, and the vault is unlocked by typing a secret equation and pressing equals.
Who it’s for
Android users who want a discreet, password-protected place for private files and conversations on their phone.
