二维码生成器 — Privacy Policy

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

This policy covers "二维码生成器" (the "App").

In plain words: a purely local QR code tool — generation and scanning both happen on your
iPhone, and the contents stay there.

1. What we collect

Nothing.

• We do not upload the QR contents you generate or scan.
• We do not upload your groups, favourites, or settings.
• 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

Generating codes

• Generation happens on your iPhone; results are saved locally or to your library if you ask.
• The groups and favourites you create are stored only on your device.

Scanning

• Scanning uses the camera in real time, and recognition runs locally on your iPhone.
• Camera frames are never saved and never uploaded.
• The camera is active only while the scanning screen is open.
• Neither generated nor scanned contents 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

• Camera: used to scan QR codes. Active only on the scanning screen.
• Photo library (read): used to pick an icon to place in the middle of a code.
• Photo library (write): used to save generated codes to your library, only when you ask.
• The App does not use speech recognition and does not read other photos in your library.
• 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 → Camera / Photos.
• Delete saved codes: remove them in the Photos app.
