Privacy policy

1. Information we process

HaoHao Go Master keeps only what it needs:

• On the device: progress, stars, streaks, rank, puzzle level, and sound settings stay on the device. They are not uploaded or backed up.
• Over the network: to compute the AI's move, the current board (size and move list) is sent by HTTPS to our server (gamequ.com), used once, then discarded. It is not stored and contains nothing that identifies the child.
• Photos on iOS: only if a guardian taps “Save to Photos”. The system asks for add-only access. We never read existing photos. Android does not ask for photo access.
• This website: no account, no cookies, no third-party analytics.

2. What we do not collect

The app has no account and no password. It embeds no analytics or ad SDK, does not read device IDs (IMEI, Android ID, OAID, IDFA), and does not ask for contacts, location, or the microphone.

3. Children's privacy

The app is for children aged 5–12. We do not build a profile for the child and do not collect the child's personal information. A guardian must read and agree before the app opens.

If a guardian thinks something was collected by mistake, or wants it deleted or corrected, contact us on WeChat pingwei1177 or at agevan@126.com. We reply within 15 business days.

4. Guardian rights

• See progress on the Me tab (it all lives on the device);
• Delete everything by uninstalling the app;
• Ask, complain, or request deletion via WeChat pingwei1177 or the email above.

After uninstall, device data is gone with the app. The server keeps nothing.

5. Policy updates

If this policy changes in substance, we raise the version and ask the guardian to agree again at launch. This page is updated at the same time. Earlier versions are available on request.
