KhaoJai Thai ("the App", "we", "us") is a Thai-language learning app published on Google Play. This Privacy Policy explains what information the App handles, how it is stored, and your rights regarding that information. We've kept this policy simple and honest because, frankly, the App doesn't collect much — and that's by design.
KhaoJai Thai is designed to work entirely on your device. We do not operate any server, and we do not collect, transmit, or store your personal information anywhere outside your phone. The only data the App keeps is stored locally on your device using standard on-device storage (AsyncStorage), and is used solely to make the App work for you. This includes:
| What's stored locally | Why |
|---|---|
| Phrases you've marked as "learned" | So your progress is remembered between sessions |
| Your daily learning streak | To show your streak on the Home and Progress screens |
| Your selected speaker preference (male/female "krub/ka" mode) | So the App remembers your preference |
| Whether you have purchased the premium unlock | So premium content stays unlocked between sessions |
None of this information identifies you personally, is linked to your name or email, or is ever sent to us or to any third party. If you delete the App, this data is permanently removed from your device.
KhaoJai Thai offers an optional one-time purchase that permanently unlocks additional content. All purchases are processed entirely by Google Play Billing. We never see, collect, or store your payment details, card numbers, or billing address — that information is handled solely by Google in accordance with the Google Privacy Policy. We only receive confirmation from Google Play that the premium unlock has been purchased, which is used to unlock content within the App.
KhaoJai Thai may request limited device permissions strictly to provide its core functionality (for example, audio playback for native Thai pronunciation recordings). The App does not access your contacts, location, camera, microphone, files, or any other personal data on your device.
KhaoJai Thai does not integrate any third-party analytics, advertising networks, crash-reporting tools, or social media SDKs. The only third party involved in the App's operation is Google Play, which distributes the App and processes subscription payments as described above.
KhaoJai Thai is suitable for general audiences and does not knowingly collect any personal information from anyone, including children. Because no personal data is collected or transmitted by the App, there is no information about children (or anyone else) for us to hold or misuse.
Since all App data remains on your own device and is never transmitted to us, there is no central database that could be breached on our end. Your device's own security features (screen lock, encryption, etc.) protect this locally stored data.
We may update this Privacy Policy from time to time — for example, if we add new features that change how data is handled. Any changes will be reflected on this page with an updated "Last updated" date. We encourage you to review this page periodically.
