Privacy Policy for Flash Tzu
Last updated: December 2025
Flash Tzu (“the App”) is a simple flash card learning application designed with the principle of zero operation costs. We respect your privacy and are committed to being transparent about how the App works and how data is (or is not) handled.
This Privacy Policy explains what information is collected, how it is used, and your rights as a user.
1.1 Personal Data
Flash Tzu does not collect, store, or process any personal data.
Specifically, we do not collect:
- Names
- Email addresses
- Phone numbers
- Account credentials
- Location data
- Contacts
- Identifiers (such as advertising IDs)
The App does not require user accounts and does not support sign-in functionality.
1.2 Usage Data
Flash Tzu does not track user behavior or analytics.
We do not collect:
- App usage statistics
- Interaction logs
- Crash reports linked to users
- Diagnostic or performance data
2. Network Requests and External Content
Flash Tzu operates entirely offline by default.
The only network request made by the App is optional and user-initiated:
- When a user chooses to download pre-made flash card sets, the App downloads ZIP files from public Git repositories.
Important notes:
- These downloads are read-only
- No data is uploaded from the user’s device
- No personal information is sent with these requests
- The App does not communicate with any proprietary backend servers
3. Local Data Storage
Flash Tzu stores data only locally on the user’s device.
This may include:
- Flash card decks created by the user
- Flash card decks imported from ZIP files
- App preferences
All stored data:
- Remains on the device
- Can be deleted by the user at any time by uninstalling the App or clearing app data
- Is never shared externally
4. Third-Party Services
Flash Tzu does not use:
- Advertising services
- Analytics SDKs
- Tracking libraries
- Third-party authentication providers
The App does not integrate with Google Analytics, Firebase Analytics, AdMob, or similar services.
5. Data Sharing
Flash Tzu does not share data with any third parties.
Because no personal or usage data is collected, there is nothing to sell, rent, or disclose.
6. Data Security
Since Flash Tzu does not collect or transmit personal data:
- There is no centralized data storage
- There is no risk of server-side data breaches
All user-created content remains under the user’s control on their device.
7. Children’s Privacy
Flash Tzu is safe for all ages.
- The App does not knowingly collect data from children
- The App complies with Google Play Families Policy
- No personal information is collected from any user, including children under 13
8. User Rights
Because Flash Tzu does not collect personal data:
- There is no personal data to access, modify, or delete
- Uninstalling the App removes all locally stored data
9. Changes to This Privacy Policy
This Privacy Policy may be updated from time to time.
When changes are made:
- The updated version will be published alongside the App
- The “Last updated” date at the top will be revised
We encourage users to review this policy periodically.
