PRIVACY-FIRST

Your scan history, notes, folders, tags, and preferences are stored locally on your device. QR Diary does not require registration and does not upload your scan history to a developer-operated server.

Camera images are processed on your device for scanning. You remain in control of any content you choose to copy, share, open, back up, or export.

ORGANIZE YOUR SCANS

Turn scattered QR results into a useful personal archive. Rename records, add notes, group related items into folders, attach tags, and quickly find what you need later.

BACKUP AND EXPORT

Optional Pro features provide additional tools such as backup, restore, CSV export, and privacy controls. Pro is planned as a one-time Google Play purchase with no subscription.

QR Diary is built for people who want a dependable scanner they can keep as their everyday QR utility: fast to open, simple to use, private by default, and free from ads.
