About

Paperlock

Read full description

Paperlock is a locked drawer for the papers that matter. Your iPhone can already scan a page. Paperlock is where the scan goes afterwards, when it is something you would not leave lying around: a passport, a lease, a tax return, a medical record. LOCKED AND ENCRYPTED • Locks as soon as you leave it. Face ID, Touch ID or your passcode opens it again. • Every scan, PDF, name and note is encrypted with AES-256 before it is stored. • The key stays in your iPhone's Keychain, on this device only. YOUR PAPERS • Scan paper with the camera. Several pages become one PDF. • Import PDFs you already have. • Give each document a name and a note, and search through both. • Open a PDF, or share a copy when you choose. BACK UP ON YOUR TERMS • A backup is one encrypted file with its own password. • You decide where it goes. Paperlock does not upload it. • A vault password opens your documents on a new iPhone. PRIVATE BY DESIGN • No account, no cloud, no server, no analytics, no ads. • The app makes no network requests at all. GOOD TO KNOW • There is no password reset. Nobody else holds your key, so nobody can recover it for you. • There is no sync. Your documents are on one phone, and a backup file is how you move them. Paperlock was called Secure Document Vault. If you have it, this update keeps your documents and encrypts them the first time you open it.
