Paperweight Privacy Policy

Effective November 1, 2026.

Paperweight is a document scanner published by Southwest Blueprints. This policy explains what happens to your information when you use it. Contact: info@southwestblueprints.com.

The short version

  • We do not collect, store, sell or share any of your data. We have no servers.
  • No ads, no analytics, no crash reporting, no tracking, no account.
  • The app does not have Android's internet permission, so it cannot send anything anywhere.
  • Your scans and their text stay on your device until you share or back them up.

What the app stores, and where

Your scanned pages, the text read from them, document titles and your settings are stored in the app's private storage on your device.

What leaves your device

Nothing, unless you send it:

  • Sharing and exports. PDFs and text files are created on your device and go to the app or place you pick in Android's share sheet or "Save to" dialog.
  • Backups. You choose where the backup file goes, for example Google Drive, Dropbox, OneDrive or your device. If you set a passphrase, the backup is encrypted (AES-256-GCM, with the key derived from your passphrase by Argon2id). We never see your passphrase and cannot recover it.

What happens to a file after you share or save it is governed by the app or service you send it to.

Locks

  • App lock (optional). Android checks your fingerprint, face or screen lock. The app never sees or stores it.
  • Locked documents (optional). Pages and their text are encrypted on your device with a key made from a passphrase you choose. If you forget it, nobody can open that document, including us.

Scanning and text recognition

Scanning uses Google Play services' on-device document scanner, which Google may download to your device the first time you scan. Text is read by an on-device text recognizer bundled with the app. The app does not upload your document images. Google Play services is a Google system app with its own privacy terms: policies.google.com/privacy.

Purchases

The optional one-time unlock is sold through Google Play. Google processes the payment and tells the app only whether the unlock was purchased. We do not receive your name, email address or payment details.

Your control

You can view, export and delete your documents in the app at any time. Uninstalling the app deletes everything it stored. Backups you saved elsewhere stay there until you delete them. Because we hold no personal data, there is nothing for us to access, correct or delete on our side; contact us with any question.

Children

The app is not directed at children under 13 and collects no data from anyone.

Changes

If this policy changes, the new version will be published at the same address with a new effective date. Because the app has no internet access, it cannot change what it collects without an app update that you install.

iPhone version: the same privacy rules

The Android-specific permission and backup references above describe the Google Play version. The iPhone version has no application networking code, developer backend, analytics, advertising, tracking or crash reporting. iOS has no Android-style internet permission switch. Apple processes the optional one-time purchase under its own privacy policy.

Private app-data directories are marked as excluded from device backups. Manual exports and backup files go where you choose through Files or the share sheet, including a cloud provider you select. Those exported files remain under your control. Delete the app, not Offload, to remove local data.

Photos, documents and text recognition, where available in this app, are processed on the device. Face ID and device passcodes, where used, are handled by the operating system. Reminders are local notifications, not messages from our servers.
