Lock It: Calculator Vault

Lock It is a private vault app hidden behind a real calculator. Hide photos, videos, notes, passwords and 2FA keys, send private messages, and make live 1:1 video and voice calls.

This is not a calculator-only app. The calculator is the face. Your vault, notes, keys, media, and optional Messages stay behind your equation.

What you get
• Real calculator for everyday math
• Unlock the vault by typing your secret equation and pressing =
• Sealed notes, media, camera captures, passwords / 2FA keys, and phone numbers on this device
• Optional Messages: 1:1 chats and groups with people you invite
• Discover: optional people board and family-friendly circles inside Messages
• Encrypted Cloud locker (Watch Bank credits or rewarded ads) — files encrypted on this phone before they leave it
• Live 1:1 video and voice: Freemium uses Watch Bank credits (1 credit = 1 min video or 3 min voice). Premium Pro includes 90 min video and 3 hr voice each week, then credits
• Vault Weather for a city or ZIP you type (no GPS)
• Encrypted account recovery for notes, keys, numbers, and settings when signed in — still needs your equation. Camera photos stay on this phone unless you put them in Encrypted Cloud

Plans
• Freemium: vault + Messages with ads (vault-home banner, occasional full-screen ads, optional Watch Bank rewarded ads). Live calls use credits. Credits also skip some full-screen ads and buy Encrypted Cloud space.
• Premium Pro ($4.99/month on Google Play): no ads, live calls with weekly minutes, extra live time with credits
• Offline Vault ($9.99 one-time on Google Play): local vault only, no ads, no Messages or live calls

Watch Bank packs on Google Play: $0.99 = 10 credits, $4.99 = 75 credits, $9.99 = 200 credits.

Privacy
Your equation is stored only as a salted hash. We cannot recover a forgotten equation. Notes and keys on this phone are encrypted (AES-GCM). When signed in, an encrypted recovery of notes, keys, numbers, and settings is stored on your account. Camera photos and imported files stay on this phone unless you add them to Encrypted Cloud. Cloud services use Firebase. Freemium ads use Google AdMob. We do not sell personal data. You must be 13+.

Account
First open: agree to Privacy and Terms, then sign in with Google or email, or Skip for a local vault (Messages needs an account later). Then set your equation. Delete cloud account data in Settings, or use the account deletion page.
