1. Introduction and effective date
Effective date: November 3, 2026
This policy applies to TileSense (Chinese and Japanese name: 牌感), an iOS app provided by independent developer 啵啵的猫粮计划 (“we” or “us”). It applies to users worldwide, including mainland China, Japan, the United States, and the European Union.
TileSense is an educational app for learning mahjong rules and tile efficiency through lessons and exercises. It has no gambling, chips, matches, or social features.
2. Information we collect
We do not collect or upload any personal information through the app. No account registration or login is required.
The app does not use third-party analytics, advertising, or crash-reporting SDKs. We do not track users or share app data with third parties.
3. Local data and how to delete it
Learning progress, settings, and similar data are stored only on your device. They are not uploaded to the developer’s or third parties’ servers. The developer cannot access this local data.
Deleting the app from your device deletes the learning progress, settings, and other local data it stores on that device. Choose “Delete App” in iOS; “Offload App” retains documents and data.
4. In-app purchases
The app’s only payment option is a one-time in-app purchase through the Apple App Store.
Apple processes payments, and the developer cannot access your payment information. Apple’s handling of payment-related information is governed by its own Privacy Policy.
5. Children’s privacy
The app is suitable for users of all ages. We do not collect personal information through the app from any user, including children under 13.
Our approach of not collecting children’s personal information is designed to comply with the relevant requirements of the U.S. Children’s Online Privacy Protection Act (COPPA).
6. Your rights
Subject to the applicable law and its conditions, you may have rights to access or obtain a copy of your personal information, correct it, delete it, or restrict or stop its processing under the EU General Data Protection Regulation (GDPR), China’s Personal Information Protection Law, and Japan’s Act on the Protection of Personal Information. The GDPR also provides rights to data portability and to object to processing in certain circumstances. You may also lodge a complaint with the relevant regulator under applicable law.
We do not collect or hold your personal information through the app, and we cannot access or manage local data on your device on your behalf. You can delete this data as explained in Section 3.
For questions about this policy or your rights, please use the contact details in Section 8.
7. Changes to this policy
We may update this policy and publish the revised version and effective date on this page.
If we introduce data collection in the future, we will update this policy and notify you within the app before collection begins. Where required by applicable law, we will obtain the necessary consent in advance.
