Privacy Policy

1. Scope

This policy applies to your installation and use of the App’s features and services, including translation, learning content display and generation, and customer support communications.

2. Information We Collect

Depending on the features you use, we may collect:

• Automatically generated identifiers: on first launch the App generates a random, anonymous identifier and credential used to keep your learning progress and purchase entitlements in sync. There is no user-facing registration or sign-in — no email address, phone number, or real name is required or collected;
• Your input content for translation, content generation, or support communication;
• Device information (OS version, device model, app version, language/region) for performance and compatibility;
• Usage data (feature usage frequency, crash logs/diagnostics if enabled) for improvement;
• Purchase/subscription data from Apple App Store and Google Play (receipt data or purchase tokens) for entitlement verification (not your full payment details);
• Identifiers generated by the app or platform for diagnostics/analytics (for example, an app instance ID), where enabled.

3. How We Use Information

We use information to provide and maintain features (translation, learning content, subscription entitlement checks), improve services and diagnose issues, process and auto-translate support conversations when enabled, and comply with legal obligations.

4. Sharing and Third Parties

We may integrate third-party services (for example, translation APIs, Apple In-App Purchase receipt validation, Google Play Billing purchase token validation, crash analytics, and optional usage analytics). These providers process data only as necessary to provide their service to us. We confirm that any third party with whom we share user data is required to provide the same or equal protection of user data as stated in this policy. We do not sell personal data and we do not share data with third parties for their marketing. We may disclose information as required by law.

5. Storage and Security

We retain information only as needed for the purposes described, then delete or anonymize it unless the law requires longer retention. We apply reasonable technical and organizational measures to reduce risks of unauthorized access, disclosure, alteration, or loss. Data in transit is encrypted; stored inputs are minimized and may be encrypted or de-identified. You can request deletion of your data at any time as described in Section 7.

6. International Transfers

Due to global infrastructure, your data may be processed on servers outside your country, subject to local laws. We take reasonable steps to comply with applicable requirements.

7. Your Rights; Data Deletion

Subject to applicable law, you may request access to, correction of, or deletion of your data, and you may withdraw consent to or restrict processing.

How to delete your data. You can request deletion of all data associated with your installation (the generated identifier, learning records, feedback conversations, and analytics data) at any time — no app installation is required:

• Email mandarinspeak@foxmail.com from any device. To help us locate your data, include the approximate date you started using the App and your platform (iOS or Android); we can also identify it from support conversations you have had in the App.

We will complete deletion within 30 days of verifying the request. Deletion is permanent: the data is erased, not deactivated or frozen. Purchase records held by Apple or Google remain governed by those platforms. Where law requires us to retain specific records (for example, transaction records for tax or fraud-prevention purposes), we retain only that data, stored separately, and delete it when the legal retention period ends.

To revoke consent to optional diagnostics or analytics, you can also contact us at the address above.

8. Children’s Privacy

The App is intended for general audiences and is not directed to children. We do not knowingly collect personal data from children below the age of digital consent in their jurisdiction. If a child’s data is collected without guardian consent, we will delete it promptly upon discovery.

9. Changes

We may update this policy and will notify you of material changes via in-app notice or other reasonable means. Updates take effect upon posting unless stated otherwise.

10. Platform Disclosures (Apple & Google Play)

This section summarizes how the App interacts with platform services to help you understand Apple App Store and Google Play disclosures.

• Purchases and Subscriptions: We use Apple In-App Purchases and Google Play Billing to process transactions. We receive non-sensitive purchase metadata (for example, receipt data or purchase tokens) to validate entitlements. Payment card details are handled by Apple or Google and are not accessible to us.
• Crash and Diagnostics: If enabled, diagnostics and crash logs may be processed by platform or third-party diagnostics services (for example, Apple diagnostics or Firebase Crashlytics) to improve stability.
• Analytics (optional): Where enabled, we may collect aggregated, non-sensitive usage metrics (for example, feature usage) to improve the App. We do not share analytics data with third parties for their advertising or profiling.
• Advertising and Tracking: The App does not sell personal data and does not use cross-app tracking for targeted advertising. We do not use the Apple IDFA or Google Advertising ID for ads.
• Data Security: Data in transit is encrypted. We minimize data retention and support deletion on request as described in this policy.

For details required by the Apple App Store App Privacy and Google Play Data Safety disclosures, the items above map to: app content you provide, device and diagnostics, purchase history/entitlements, and optional usage analytics. Categories not listed are not collected.
