采色精灵 — Privacy Policy

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

This policy covers "采色精灵" (the "App").

In plain words: a purely local colour picker and palette tool — picking, palette building and
export all happen on your Mac. No network access, no uploads.

1. What we collect

Nothing.

• We do not upload the colours, palettes, or swatches you pick.
• We do not upload your images or files.
• No analytics, no tracking, no advertising SDK.
• All settings stay on your own Mac, inside the app sandbox:
  ~/Library/Containers/com.mac.gcdev.g18/

2. How the App handles your data

How colour picking works

• Picking uses macOS's own sampler (NSColorSampler). The system reads the on-screen colour;
  the App only receives the single colour value you click on.
• The App does not use Screen Recording permission and cannot see anything else on screen.
• Picking from an image reads only images you explicitly pick in the system picker.
• Picked colours and palettes stay on your Mac and are never uploaded.

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 permission, and does not require Screen
  Recording (picking is done by the system sampler).
• It 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.g18/
• Uninstalling the App also removes its sandboxed data.
