Information HSK Deck Collects
HSK Deck currently does not collect personal information on our servers. The app does not ask for your name, email address, phone number, precise location, contacts, photos, microphone, camera, health information, government identification, or financial card details.
Local App Data
HSK Deck stores learning-related information locally on your device to make app features work. This may include selected study level, review progress, quiz progress, app preferences, and premium unlock state. Local app data remains on your device and is not sent to our servers.
How Information Is Used
Local app data is used only to provide app functionality, such as continuing your study progress, showing locked or unlocked levels, remembering preferences, and supporting review features.
Purchases
HSK Deck offers an optional one-time lifetime unlock through Google Play Billing. Payment processing is handled by Google Play. We do not receive or store your payment card details. Google Play may process purchase information according to Google’s own policies and the Google Play terms that apply to your account.
Ads and Tracking
HSK Deck does not display ads and does not use advertising trackers.
Third-Party Services
HSK Deck uses Google Play Billing for optional in-app purchases. The app may use platform services available on your device, such as text-to-speech audio output, to provide learning features. HSK Deck does not use these features to collect personal information on our servers.
Data Sharing
We do not sell personal information. We do not share personal information with advertisers, data brokers, or analytics providers. Purchase processing is handled by Google Play as described above.
Security
Because HSK Deck currently stores learning progress locally and does not transmit personal learning data to our servers, server-side transmission of personal app data does not occur. If future versions add online features, we will use reasonable safeguards such as HTTPS for data in transit and update this Privacy Policy before or when those features become available.
Data Retention
Local app data remains on your device until you delete it, clear app storage, or uninstall the app. We do not maintain a server account database for HSK Deck users at this time.
Data Deletion
Because HSK Deck does not require an account and stores learning progress locally, you can delete app data by uninstalling the app or clearing app storage in your device settings. See the Data Deletion page for step-by-step instructions.
Permissions
HSK Deck is designed as a vocabulary learning app and does not require access to sensitive Android permissions such as location, contacts, camera, microphone, SMS, call logs, or health data for its core features.
Children
HSK Deck is intended for general language learners and is not specifically directed to children. If a parent or guardian believes a child has provided personal information to us, they can contact us through the Support page.
International Users
HSK Deck may be available to users in different countries. You are responsible for using the app in compliance with laws that apply to you. If future features require server processing, this policy will be updated to describe applicable data handling.
Consistency With Google Play Data Safety
Our Google Play Data Safety answers should match this Privacy Policy. Based on the current app behavior, HSK Deck itself does not collect or share user data with our servers. If the app changes in a way that collects, transmits, or shares user data, we will update the Data Safety form and this Privacy Policy.
Changes
We may update this Privacy Policy from time to time. Updates will be posted at this same URL with a new effective date.
