DMTPuzzle — Privacy Policy

1. Who we are

DMTPuzzle is developed and published by DataMatrix Technology Solutions Pvt. Ltd.. If you have any questions about this policy, you can contact us at kunal.gupta35@gmail.com.

2. Information we do not collect

We do not collect:

• Your name, email address, or any contact information
• Your device's precise or approximate location
• Device identifiers (IMEI, Advertising ID, etc.)
• Photos, contacts, or any other files from your device
• Crash reports or analytics data sent to our servers
• Payment or billing information

3. Data stored locally on your device

The app stores the following data only on your device using a local SQLite database. This data never leaves your device and is not accessible to us:

• A display name you choose ("Player" by default)
• Your game progress — puzzles played, best times, star ratings, and scores
• Your sound preference (on/off)
• The state of an in-progress puzzle (so you can resume it later)

This data is removed when you uninstall the app or clear the app's data from your device settings.

4. Internet access

The app requires an internet connection to download puzzle images and to fetch the puzzle catalogue from our server at https://www.dmtspl.com/. Only the following requests are made:

• Downloading the puzzle list file (puzzles.json)
• Downloading puzzle images (e.g., 1.jpg … 112.jpg)

These are standard HTTP downloads. We do not log your IP address or associate any download request with an individual user.

5. Third-party services

DMTPuzzle does not integrate any third-party SDKs for advertising, analytics, crash reporting, or social login. No data is shared with third parties.

6. Children’s privacy

DMTPuzzle is suitable for all ages. Because we do not collect any personal information, the app is safe for children under 13 and complies with the Children's Online Privacy Protection Act (COPPA) and Google Play's Families Policy.

7. Data security

Since no personal data is transmitted to or stored on our servers, there is no server-side data to secure or breach. All game data remains entirely on your device under the protection of the Android operating system.

8. Changes to this policy

If we update this Privacy Policy, we will revise the effective date at the top of this page and publish the updated version at the same URL. We encourage you to review this page periodically.
