Lockgrid: Private Photo Vault

About this app

Lockgrid keeps your scanned IDs, documents, photos and private notes encrypted on your phone. No account, no server, and it works offline.

DOCUMENTS FIRST
• Scan a passport, ID card or insurance card with the camera straight into an encrypted PDF (Lockgrid Pro)
• Import PDFs and any other file from Files (Lockgrid Pro). Search a vault by item name, and by the text inside imported PDFs on Android 15 and later. Everything about an item is kept only inside that vault's encrypted index

HAND OVER ONE THING
• Open a photo or document and tap Show Only This before you hand your phone to someone
• Only that item stays on screen: swiping, sharing and deleting are off
• The way out locks Lockgrid

OFFLINE, ON YOUR PHONE
• AES-256-GCM encryption, done on your device
• No account, no sign-up, no servers, no analytics. Nothing is sent to us. The only thing that talks to the internet is Google Play's own billing library, for purchases
• Locks the moment you leave the app, and Recents shows nothing from inside it

YOUR PATTERN IS THE KEY
• Trace a pattern of 4 or more dots on the 4×4 grid to unlock
• Another pattern opens a separate vault. Once it's open, each vault shows its own color and mark, worked out from its key, and the name you give it. The lock screen looks the same for every vault
• Your pattern is never stored (unless you turn on biometric unlock for one vault, which seals that pattern with your phone's hardware-backed Keystore)

RE-KEY AND MOVE
• Change a vault's pattern any time. Everything in it is re-encrypted for the new pattern, chunk by chunk, without decrypting to disk, and the vault keeps its name and color
• Move selected items to another vault by tracing that vault's pattern
• Share decrypted copies out whenever you need them

ALSO
• Private camera: photos and videos that never touch your gallery (Lockgrid Pro)
• Encrypted notes for PINs, codes and recovery words
• Photos and videos from your library through Android's photo picker, with no access to the rest of it
• Hide the pattern while you trace it
• A pattern you've never used opens an empty vault, so a second, harmless vault is always one pattern away
• Your vaults move to a new phone with Android's device-to-device transfer, still encrypted

FREE AND PRO
Free: as many vaults as you like, each holding up to 20 photos and notes, with its own name and color, search by name, and Show Only This.

Lockgrid Pro is optional. Buy it once (Lifetime) or choose the yearly subscription (new subscribers get a 3-day free trial). Pro unlocks:
• Unlimited items in every vault
• Videos and any file, including PDFs
• The document scanner
• The private camera
• Biometric unlock for one vault of your choice

Payment is charged to your Google Play account when you confirm the purchase. The yearly subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in Google Play › Payments & subscriptions › Subscriptions. Lifetime is a one-time purchase.

There is no password reset: if you forget a pattern, that vault can't be opened by you, by us or by anyone.
