推广文案 — Privacy Policy

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

This policy covers "推广文案" (the "App").

In plain words: a promotional-copy generator. To understand what a project is, it reads the
project's directory structure — and that "profile" is sent to the AI service you configure.
That is spelled out below.

1. What we collect

Nothing.

• We do not upload your source code — the project profile contains only the directory name,
  the directory structure, and a list of file names. No file contents.
• We do not upload documentation already in the project — if the folder already contains a
  README or similar, the App uses it directly and does not call the AI at all.
• No analytics, no tracking, no advertising SDK.
• All settings stay on your own Mac, inside the app sandbox:
  ~/Library/Containers/com.mac.gcdev.g29/

2. How the App handles your data

What the project profile contains

When you ask the App to write copy for a project, it first scans that project on your Mac and
builds a profile consisting of:

• the project folder name
• the directory structure (which subfolders exist, and how they nest)
• a list of source and resource file names

The profile contains no file contents. It describes what the project looks like, not what
the code says.

• If the project already contains documentation, the App uses it and neither scans nor calls the AI.
• The profile is built on your Mac and is sent only when you actively press generate.

Writing the copy

• A request is made only when you press generate, sending the profile and your instructions to
  the AI service you configured.
• The copy you generate is stored on your Mac and can be exported by you.

3. The only things that go online

AI copywriting is the only thing that goes online — and only when you press generate.

• The request goes to the AI service you configured and contains the project profile text plus
  your instructions. See "Third parties" below.
• The App uses no Apple in-app purchase, and makes no other network requests whatsoever.

4. Permissions

• The App does not require Accessibility or Screen Recording permission, and does not use the camera or microphone.
• It only accesses project folders 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

• Copywriting uses 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 the project profile text plus your instructions — the folder name, the
  directory structure and a list of file names. No file contents.
• The API key is entered by you and stored in your Mac's Keychain; the developer cannot read it.
• These requests go directly between you and the AI service you chose; please also review that
  service's own privacy policy.
• If you would rather not send your project structure, do not use the generate feature.

6. Your rights

• Delete your settings: just remove ~/Library/Containers/com.mac.gcdev.g29/
• Delete the saved AI key: remove the corresponding entry from your Mac's Keychain
• Uninstalling the App also removes its sandboxed data.
