Privacy policy
Last updated: October 20, 2026
Play stays local. Feedback is your choice.
Operator and contact
Boardset and this website are operated by 深圳市予人智能科技有限公司. Contact person: Tiandi Lai. Support, privacy and deletion requests: tiandi.larry@gmail.com. This policy applies to Boardset, not our other products.
Data kept on your device
Games, move histories, learning progress, appearance, language and audio preferences are stored on your device. We do not provide accounts or game cloud sync and do not automatically upload games or learning records. Device backups depend on your Apple and system settings. Feedback drafts are excluded from cloud backup.
Local AI and Apple purchases
Board-game AI runs on your device. Game positions are not sent to an external AI provider. Apple handles payments and restoration. The app uses verified transactions to determine access and does not receive card details, Apple passwords or your Apple Account email. Apple processes store data under its own policies.
Feedback you choose to submit
Tapping Submit sends the feedback ID, category, game and description. An email address and one screenshot are optional; including app version, OS version and device model can be switched off. You can submit without an email. Only the image selected through the system photo picker is accessed; the app resizes and re-encodes it to remove original metadata. Avoid personal information unrelated to your issue.
Purposes, providers and network data
We use feedback only to respond, troubleshoot, support purchases and improve the app. We do not sell it or use it for advertising. Our website and feedback service use Tencent Cloud hosting in Hong Kong. Submitted feedback is stored and processed in Hong Kong. Apple provides distribution, the system photo picker and purchases. Network infrastructure processes source IPs for delivery and abuse prevention. The feedback database does not store raw IPs; rate limits use an HMAC identifier with a temporary random key and expire after one hour. This website has no advertising or analytics cookies or third-party tracking scripts.
Retention and security
Feedback, optional contact email, screenshot and diagnostics are stored together and removed after 180 days by cleanup at startup and hourly while the service runs. Transmission uses HTTPS and the database is not publicly served. Drafts stay on your device and are cleared after successful submission or when you choose Clear draft. Support correspondence or records legally required for a dispute are kept only as long as necessary or required.
Access, correction and deletion
You can clear local drafts, remove a screenshot, turn off diagnostics and stop submitting feedback. Email support for access, correction or deletion of submitted data, with the feedback ID or enough detail to locate the record. We verify and respond to requests; anonymous records may be impossible to identify without sufficient information. Deleting the app removes local data but does not automatically delete previously submitted feedback or cancel an Apple purchase. Non-consumable purchases can be restored with the same Apple Account.
Minors and changes
The app is not specifically designed for children. Minors should use purchases and feedback with guardian guidance. Do not submit sensitive information about children. We update this policy for material changes and provide notice or request consent when required.
