Normal Map — Privacy Policy

Last updated: October 7, 2026
Effective: October 7, 2026

This policy covers "Normal Map" (the "App").

In plain words: a purely local normal-map generator — your images and the results never
leave your Mac.

1. What we collect

Nothing.

• We do not upload your images, file paths, or file names.
• We do not upload the normal maps you generate.
• We do not upload your parameters or settings.
• No analytics, no tracking, no advertising SDK.
• All settings stay on your own Mac, inside the app sandbox:
  ~/Library/Containers/com.mac.gcdev.g25/

2. How the App handles your data

How your images are processed

• Normal maps are computed entirely on your Mac (using Apple's Core Image).
• Only images you explicitly pick in the system picker are read; nothing else is scanned.
• Neither the process nor its results are uploaded, and nothing is written to a log.

3. The only things that go online

• App Store in-app purchase (unlocks the full feature set).
  Payment, receipts and refunds are handled by Apple. We never see your payment details and
  never receive your name or account.
• Purchase verification: after a purchase or restore, the App sends Apple's
  transaction identifier and the App's bundle identifier to the developer's server to
  confirm the transaction is valid. No receipt file and no device identifier are sent.
  The App also submits a randomly generated local identifier with the transaction so the
  purchase can be matched up; it contains none of your personal information.
  Beyond this the App makes no network requests.

4. Permissions

• The App does not require Accessibility or Screen Recording permission, and does not use the camera or microphone.
• It only accesses files you explicitly grant through the system picker.
• Uninstalling the App removes its sandboxed settings.

5. Third parties

The App includes no third-party analytics, advertising, or data-collection SDK. Any network activity involving Apple is itemised under "the only things that go online" above.

6. Your rights

• Delete your settings: just remove ~/Library/Containers/com.mac.gcdev.g25/
• Uninstalling the App also removes its sandboxed data.
