Privacy Policy

Last updated: September 12, 2026

1. Introduction

Thai Reader ("the App") is an app for learning to read the Thai script — its alphabet, tones, and vocabulary — developed by TMD ("we", "us", "our"). This Privacy Policy explains how we handle information when you use the App.

2. Information We Do NOT Collect

We do not collect any personal information. Specifically:

• No names, email addresses, or contact information
• No account or sign-up — the App requires no login
• No location data
• No device identifiers or advertising IDs
• No advertising or third-party tracking of any kind
• No cookies or similar technologies
• No microphone, camera, or photo access
• No crash reports or usage data sent anywhere unless you opt in — see Section 8

3. Data That Stays On Your Device

The App stores the following information locally:

• Your chosen interface language (one of 22)
• Your learning progress — which level exams (quiz and Word Builder) you have passed
• Your settings — daily-reminder preference and time, iCloud-sync preference
• Whether you have completed the first-run introduction
• Your purchase entitlement (whether you own the full unlock)

This data never leaves your device except to be synchronized to your own private iCloud, as described below.

4. iCloud Sync

If you are signed in to iCloud and iCloud Drive is enabled, the App synchronizes your learning progress across your own Apple devices using Apple's CloudKit:

• The data is stored in your own private iCloud container, managed by Apple
• We have no access to any iCloud data
• iCloud sync can be disabled at any time from the App's Settings screen
• The learning content itself (Thai letters, words, audio, illustrations) ships with the App and is never synchronized — only your own progress is

5. In-App Purchases

Thai Reader offers a single one-time, non-consumable in-app purchase ("Unlock everything") that unlocks the Tones and Words sections, quizzes, and games beyond the free Alphabet. All purchases are processed by Apple through the App Store:

• We do not see or store any payment information
• Apple manages transaction receipts; we only read whether the purchase is active via Apple's StoreKit 2 API
• The purchase is Family Sharing eligible, as configured in App Store Connect
• A Restore Purchases button in Settings lets you re-verify your purchase on any device

6. Notifications

If you opt in, the App can schedule an optional daily reminder to keep your reading practice going. These are local notifications scheduled on your device by iOS — no data is sent to us or anyone else, and you can turn them off at any time in the App's Settings or in iOS Settings.

7. Audio Narration

Every letter and word is accompanied by a pre-recorded audio clip that ships inside the app bundle. Playing these clips happens entirely on your device; the App does not stream audio from any server and never uploads any audio. The App works fully offline.

8. Anonymous Usage Statistics (Opt-In)

With your explicit consent — asked once, right after the introduction, and changeable at any time in the App's Settings under "Anonymous statistics" — Thai Reader can send fully anonymous usage measurements using Google Firebase Analytics. This is off by default and nothing is sent unless you accept.

If you accept, we measure things like:

• Which sections and lessons are opened, and whether a quiz round is passed or failed
• Whether the daily reading streak is kept or broken
• Whether the one-time unlock is purchased (Apple's own price and currency for your storefront — never a fixed amount)
• Coarse technical data collected automatically by Firebase (app version, device type, country, approximate session length)

This data is not personally identifiable: we do not collect your name, email, or any account identifier, and no data is ever sold or shared with advertisers. You can withdraw consent at any time from Settings, which stops all future measurement immediately.

9. Third-Party Services

The App does not integrate any advertising or third-party tracking SDKs. The third-party services it uses are:

• Apple StoreKit — for processing the in-app purchase
• Apple CloudKit / iCloud — for optional synchronization of your own learning progress
• Google Firebase Analytics — only if you opt in, as described in Section 8

10. Children's Privacy

The App contains no advertising, no external links, no social features, no chat, and no personally identifiable data collection. It is safe for users of any age who are learning to read Thai. We do not knowingly collect personal information from anyone, including children under 13.

11. Data Retention

Since we do not collect any personally identifiable data, there is nothing of that kind for us to retain. Local data (preferences, progress) stays on your device — and optionally in your own iCloud — until you delete it from within the App or remove the App entirely. Anonymous usage statistics (Section 8), if you opted in, are retained by Firebase under Google's standard retention settings and are never linked back to you.

12. Your Rights

Because we do not collect any personally identifiable data, most data-subject rights (access, portability, erasure) are fully within your control: uninstalling the App and signing out of iCloud removes every trace of your use of the App. Withdrawing analytics consent in Settings stops all future anonymous measurement immediately.

13. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated "Last updated" date. We encourage you to review this page periodically.
