Privacy Policy for Thai Letter Tracer

1. Information We Collect

a. Local / guest use (no account)

You can use the App without creating an account. In that case:

• Tracing practice (stroke guides, accuracy feedback, lives, tokens, scores, streaks, badges, etc.) is stored on your device using local app storage.
• We do not require a name, email, or account for guest play.
• Stroke geometry used for feedback is processed on-device for gameplay; we do not upload raw stroke drawings as a separate personal profile.

b. Optional account (email or Google)

You may optionally create or sign in to an account to sync progress across devices. When you do, we process:

• Account identifiers — email address (for email/password accounts), Google account identifiers and basic profile information Google provides when you use Google Sign-In (such as email, display name, and profile photo URL if available).
• Authentication data — handled by Google Firebase Authentication (passwords are not stored by us in readable form; authentication is provided by Firebase).
• Cloud progress data — gameplay progress associated with your account (for example lifetime score, high scores, daily streak metadata, badge ids, unique letters completed, mode stats, and similar fields) stored in Google Cloud Firestore under your account user id.

Account creation is optional. Guest play remains available without signing in.

c. Advertising (via Google AdMob)

The App displays advertisements to support free access. We use Google AdMob (part of Google LLC) to serve ads.

AdMob automatically collects and shares certain data for ad serving, personalization (where permitted), analytics, and fraud prevention, including:

• Device and account identifiers (e.g., Android Advertising ID, app set ID)
• IP address (which can infer approximate location)
• User interactions with ads and the app (e.g., views, clicks)
• Diagnostic information (e.g., crash logs, performance data)

This data helps deliver relevant ads and measure performance. We do not sell this data. It is handled primarily by Google.

For details on Google's data practices, see:
Google Privacy Policy
AdMob Policies

We may use Google's User Messaging Platform (UMP) to request your consent for personalized ads (required in regions like the EU/EEA, UK, Switzerland). You can opt out of personalized advertising via your device settings (Android → Settings → Google → Ads) or Google's My Ad Center.

We do not collect sensitive data categories such as health, race, or religion, and we do not sell personal data to third parties.

2. How We Use Information

• Local progress — To run gameplay on your device (scores, lives, streaks, badges, settings such as theme and audio).
• Account & cloud progress — To authenticate you, sync and restore progress across devices, and provide account features you request (including account deletion).
• Ad-related data — Handled by Google AdMob to show ads, improve relevance (if consented), detect fraud, and analyze performance.
• Support — If you email us, to respond to your request (for example account or data questions).

We do not use data for purposes unrelated to operating and improving the App.

3. Third-Party Services

• Google AdMob — Advertising (see links above).
• Google Play Services — App distribution and platform services; subject to Google's Privacy Policy.
• Google Firebase (Authentication and Cloud Firestore) — Optional account sign-in (email/password, Google) and cloud progress sync/storage. Subject to the Google Privacy Policy and Firebase privacy information.

The App does not currently use separate third-party analytics or social SDKs beyond the services listed above.

4. Children's Privacy

The App is suitable for learners of many ages, including children learning Thai. We do not knowingly collect personal data from children for marketing. Optional accounts should only be created by someone with authority to do so (for example a parent/guardian). AdMob and platform settings may restrict certain ad personalization for children’s apps. If you believe a child has provided personal data inappropriately, contact us and we will take appropriate steps.

5. Data Security

We use reputable infrastructure (including Google Firebase) and access controls (for example Firestore rules that restrict each user’s cloud progress to their own signed-in account). No method of transmission or storage is 100% secure. Guest/offline features keep progress on-device and do not require an account.

6. Your Choices and Rights

• Use the App as a guest without creating an account.
• Sign in optionally to sync progress; sign out anytime in Settings.
• Delete your account and cloud data in the App (see Delete your Thai Letter Tracer account above).
• Opt out of personalized ads via device settings or My Ad Center.
• Under applicable laws (e.g. GDPR, UK GDPR, CCPA/CPRA), you may have rights to access, correct, or delete personal data — contact us to exercise them. We may need to verify your identity before fulfilling a request.

7. Data Retention

• Guest / local data — Stays on your device until you clear app data, uninstall, or use in-app options that reset progress.
• Account & cloud progress — Kept while your account remains active so sync works; removed when you delete your account as described above (subject to brief processing time and any legal retention requirements).
• Support emails — Kept as long as needed to handle your request and for ordinary business records.

8. Changes to This Privacy Policy

We may update this policy. Changes will be posted here with an updated date. For material changes, we may also provide in-app notice or update the Play Store listing.
