## About

Lock It: Calculator Vault is an Android app that looks and works like an ordinary calculator. Type your own secret equation, press =, and it opens a private vault for your photos and videos, notes, passwords and 2FA codes, all encrypted with AES-256 on your phone.

It also includes private messages and live video or voice calls, but only with people you invite by key or QR code, plus Encrypted Cloud for sending files up to 1 GB. Your equation is stored only as a salted hash, so it cannot be seen or recovered by anyone else. A local vault works without an account.

It is free with ads. Premium Pro is $4.99 a month, and Offline Vault is a $9.99 one-time purchase.
