Your data
Local records
Completion, hint history, daily challenges, expressions and settings stay on this device. Bank updates do not upload them. There is no game account or cross-device cloud sync.
Delete and restore
Android: find this app in system Settings, open Storage and clear app data, or uninstall it. This removes progress and preferences; clearing cache alone does not. System backups may restore old records, so review backup settings too. Browser: clearing site data may affect other apps on the same domain; check the scope first.
Other data
Local deletion does not delete server logs or email. You or a guardian can request privacy information, access or deletion using the email below. We explain any limits due to legal retention or unresolved disputes and restrict storage to what is necessary. This notice is updated when practices change. The question bank, directory and website are hosted on Tencent Cloud in Beijing. Security logs for this app’s website paths contain time, IP, method, path without query parameters, status, response size and duration. They are kept for at least six calendar months and expired archives are removed daily. We do not log request bodies, query parameters, cookies or tokens. Ordinary diagnostics retain only time, severity and error category for seven days, without raw requests; legally required security records are excluded from this shorter period. Email shares your address and submitted content with us and Microsoft. Our working copies are deleted 90 days after resolution; our own email backups may remain for up to 30 additional days. Open cases are reviewed periodically; legal holds and unresolved disputes are handled separately with restricted use. Cloud-provider and Microsoft logs and backup retention/deletion remain unverified; immediate complete deletion by those providers is not promised. Do not send passwords, children’s identity details or unrelated sensitive information.
