1. Introduction
This Privacy Policy applies to all mobile applications developed and published by Shih-Kung Chen (“Service Provider”, “we”, “our”, or “us”) on Google Play and the Apple App Store.
All apps provided by the Service Provider are generally offered as Ad-Supported services and may include optional In-App Purchases. Your continued use of any of these applications signifies your agreement to this Privacy Policy.
2. Information Collection and Use
The Applications themselves do not collect or store any personal information. However, they use third-party services (such as Google AdMob and Google Play Services) that may collect limited, automatically transmitted information for analytics and advertising purposes.
Examples of automatically collected data may include:
- Device type and operating system version
- Advertising ID (for ad personalization or frequency capping)
- App usage data (e.g., impressions, clicks)
- General location (country or region, not precise GPS)
For detailed information on how these third-party services handle data, please review:
Google Privacy Policy
3. User-Provided Information
Our Applications do not require you to register, sign in, or submit personal details. We do not collect names, email addresses, phone numbers, or any user-entered data. All app features are available without registration.
4. Your Data Protection Rights (GDPR and Global Privacy Laws)
If you live in the European Economic Area (EEA) or another region with privacy regulations, you may have rights to access, correct, or delete personal data.
Since our apps do not collect or store personal data directly, any such data is handled by third-party providers such as Google AdMob.
If you wish to exercise your data protection rights, please contact:
5. Third-Party Services Used
The Applications may use the following third-party services:
- Google AdMob (advertising)
- Google Play Billing / Apple In-App Purchases
Each third-party service operates under its own privacy policy:
Google Privacy Policy
Apple Privacy Policy
6. Children’s Privacy
Our Applications are rated 4+ on the App Store and suitable for general audiences. They are not specifically directed to children under 13 years of age, and we do not knowingly collect any personal data from children.
If you believe that a child has provided personal data through a third-party service (e.g., via ad interaction), please contact the relevant provider (Google or Apple) to request deletion.
7. Security
We value your trust and are committed to protecting your information. Our apps do not store personal data on our servers. Third-party services we rely on (such as Google) use standard industry practices to safeguard information.
8. Changes to This Privacy Policy
This Privacy Policy may be updated periodically. Any updates will be posted on this page with a new “Last Updated” date. You are encouraged to review it regularly.
