Luis MAR LABS ("we," "our," or "us") operates this language learning application (the "Service"). This page informs you of our policies regarding the collection, use, and disclosure of personal data when you use our Service and the choices you have associated with that data.

1. Information Collection and Use

We do not require you to create an account to use the application. The app functions offline for its core features, and we do not collect, store, or share any personally identifiable information (such as names, addresses, or phone numbers) directly through the app.

2. Local Storage and App Data

Your progress, such as completed exercises or active unit status, is saved locally on your device. We do not sync this data to external servers or cloud services without your explicit permission. If you delete the app, this local data will be removed.

3. Third-Party Services

The app utilizes the built-in Android Text-To-Speech (TTS) engine provided by Google to read Chinese characters aloud. This service is provided directly by the Android Operating System, and its usage is governed by Google's Privacy Policy. We do not send your voice data to any of our servers.

4. Children's Privacy

Our Service is suitable for users of all ages, including children. However, because we do not collect any personal data, we do not knowingly collect personally identifiable information from anyone under the age of 13.

5. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date.
