长图拼接 — Privacy Policy

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

This policy covers "长图拼接" (the "App").

In plain words: a purely local image stitcher — it joins several screenshots into one long
image, entirely on your iPhone.

1. What we collect

Nothing.

• We do not upload your images or the stitched result.
• We do not upload your stitching settings or usage history.
• No analytics, no tracking, no advertising SDK.
• The App has no server of its own — nothing reaches us.

2. How the App handles your data

How your images are processed

• Only photos you explicitly select are read (through the system photo picker).
• Stitching runs entirely on your iPhone (using Apple's built-in image frameworks).
• The result is saved where you choose, or to your library if you ask for that.
• 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.
• Before purchase the App checks network reachability once (a request to apple.com carrying
  no content).
• Beyond this the App makes no network requests.

4. Permissions

• Photo library (read): used to pick the photos you want to stitch.
• Photo library (write): used to save the result, only when you ask.
• The App does not use the camera, microphone, or speech recognition.
• You can revoke these at any time in Settings → Privacy & Security.

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 in-app data: uninstall the App.
• Revoke permissions: iOS Settings → Privacy & Security → Photos.
• Delete generated images: remove them in the Photos app.
