Privacy Policy

Last Updated: September 22, 2026

Applicable to all ad-free applications developed by Binh Nguyen, whether offered as completely free, paid upfront, or featuring optional in-app purchases.

Information Collection and Use

This application does not collect, track, or transmit any personal data. I (the developer) respect your privacy and do not collect any personally identifiable information from you.

Your content, progress, and settings are stored locally on your device using local storage or an SQLite database. Since local databases may be accessible through file management tools on your device, please avoid storing sensitive personal credentials within the app.

I do not share, sell, rent, or disclose any of your data to third parties under any circumstances. Furthermore, these applications do not integrate third-party tracking, advertising SDKs, or analytics frameworks.

Payment

If an application requires an upfront purchase or offers optional in-app purchases, all payment transactions are handled entirely and exclusively by the official platform store—the Apple App Store (for iOS/macOS) or Google Play Store (via Google Play Billing for Android). I never collect, process, or store your financial or payment card information (such as credit card numbers or billing addresses). For more details, please review the respective store privacy policies:

Children's Privacy

I place the utmost importance on protecting the privacy of young users. The applicability of specific child protection standards depends on the classification of each individual application:

Applications Designed for Children and Families: If an application is explicitly designated for children or includes children in its target audience (such as educational games or early-learning utilities), it is fully compliant with the Children's Online Privacy Protection Act (COPPA) and international standards. These applications do not collect, store, transmit, or share any personal information or device identifiers from children under the age of 13 (or the applicable age in your jurisdiction). Furthermore, they do not contain third-party SDKs, behavioral tracking, or inappropriate content.
General Audience Applications: For applications intended for a general audience or users aged 13 and older, I do not knowingly solicit or collect personal data from children under 13.

If you are a parent or legal guardian and believe that your child has provided any personal information through my applications, please contact me immediately so that appropriate corrective actions can be taken.

Changes to This Privacy Policy

I may update this Privacy Policy from time to time. Any changes will be posted directly on this page with an updated "Last Updated" date. Please check this page periodically for updates.
