商店预览 — Privacy Policy

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

This policy covers "商店预览" (the "App").

In plain words: an App Store asset tool — screenshot previews, copywriting, compliance checks.
Image assets are composed on your Mac and never uploaded. Text leaves your Mac only when
you actively use the AI copywriting feature.

1. What we collect

Nothing.

• We do not upload your screenshots, templates, backgrounds, or any image — previews are composed on your Mac.
• We do not upload your project or app information, other than the text you actively send
  when using the AI feature.
• No analytics, no tracking, no advertising SDK.
• All settings stay on your own Mac, inside the app sandbox:
  ~/Library/Containers/com.mac.gcdev.g09/

2. How the App handles your data

Screenshot previews

• Previews (store screenshots with frames, backgrounds and captions) are composed and exported
  entirely on your Mac.
• Images are never uploaded, and the AI feature never receives them.
• Only screenshots and backgrounds you explicitly pick in the system picker are read.

AI copywriting (optional, you configure it)

• A request is made only when you press generate, sending the text you chose to process
  (store copy / release notes / compliance text) to the AI service you configured.
• The API key is entered by you and stored in your Mac's Keychain; the developer cannot read it.
• If you never use the feature, no request is ever made to an AI service.

3. The only things that go online

• AI copywriting (only when you press generate): sends text to the AI service you configured.
  See "Third parties" below for details.
• 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.

AI service

• The "store copy / release notes / compliance check" features use an AI service you configure
  yourself. The default endpoint is DeepSeek (api.deepseek.com); you may point it at any
  OpenAI-compatible endpoint.
• What is sent is text (the copy you chose to process). No images and no files are sent.
• The API key is stored in your Mac's Keychain and cannot be read by the developer.
• These requests go directly between you and the AI service you chose; please also review that
  service's own privacy policy.

6. Your rights

• Delete your settings: just remove ~/Library/Containers/com.mac.gcdev.g09/
• Delete the saved AI key: remove the corresponding entry from your Mac's Keychain
• Uninstalling the App also removes its sandboxed data.
