 HSK4Mastery — Privacy Policy

Last Updated: October 12, 2025

Thank you for using HSK4Mastery. We built this app to be simple, private, and safe. This Privacy Policy explains what information we collect and how we handle it.

In short: HSK4Mastery does not collect, store, or transmit any personal data. The app is designed to work fully offline and does not require an account.

What We Collect

* We do not collect any personal information.

* We do not collect usage analytics or telemetry.

* We do not collect device identifiers or location data.

* We do not display ads and do not share data with advertisers.

Account and Sign‑In

* No account is required to use HSK4Mastery.

* We do not provide or integrate any sign‑in mechanism (email, phone, social, SSO, etc.).

Offline by Design

* The app works entirely offline, including in airplane/flight mode.

* All learning content is bundled with the app package and available without an internet connection.

* The Android manifest does not request Internet or network state permissions.

On‑Device Processing and Storage

* All app features run on your device. Any settings or learning progress (if stored) are kept locally on your device’s private app storage.

* We do not sync data to any server or third‑party service.

* You can clear local data at any time by uninstalling the app or using your device’s “Clear storage/data” option for the app.

Note: If your device’s system-level backup is enabled (e.g., Android backup/restore), the operating system or your chosen backup provider may back up app data as part of your device backup. We do not receive, control, or access those backups.

Permissions

HSK4Mastery does not request sensitive permissions such as Internet, network state, location, contacts, camera, or microphone. The app is built to function without them.

Children’s Privacy

HSK4Mastery is suitable for general audiences and can be used by learners of different ages. Because we do not collect personal information, we do not knowingly collect personal data from children. If you believe we have inadvertently collected any information, please contact us and we will address it promptly.

Third‑Party Services and SDKs

* We do not use analytics, advertising, crash reporting, or social media SDKs.

* We do not share data with third parties.

Security

Because data stays on your device and is not transmitted to our servers, your privacy risk surface is minimized. We follow platform best practices and only use reputable, open Android components for local functionality.

Changes to This Policy

We may update this Privacy Policy to reflect app or legal changes. Material updates will be reflected by the “Last Updated” date above. Continued use of the app after an update constitutes acceptance of the revised policy.
