Privacy Policy

Effective date: September 5, 2026
Developer: Lumen Games
App: Lumen CrossMath
com.lumengames.crossmath

This Privacy Policy explains how Lumen CrossMath (“we”, “us”, or “the App”) handles information when you use our mobile application.

1. Information we collect

Lumen CrossMath is designed to work primarily on your device.

We may store the following information locally on your device (for example via app storage):

  • Game progress (levels completed, scores, XP, streaks, settings)
  • Optional profile details you choose to set (such as display name, country, and avatar image)
  • App preferences (sound, language-related choices, and similar settings)

We do not require you to create an account to play.

We do not intentionally collect sensitive personal data such as exact location, contacts, microphone audio, or camera access beyond optional avatar selection you initiate yourself.

2. How we use information

Information stored on your device is used only to:

  • Save and restore your game progress
  • Personalize your in-app profile and experience
  • Improve gameplay continuity between sessions

3. Internet access

The App may request internet permission for features such as:

  • Opening the Play Store page (for ratings)
  • Future optional online features (for example cloud profile sync), if enabled later
  • Advertising services, if ads are enabled in a future update

If online features are not enabled, your progress remains on your device.

4. Advertising

The current release may include or later introduce rewarded or other ads (for example via Google AdMob). If ads are shown, advertising partners may collect device identifiers and usage data according to their own privacy policies, to provide and measure ads.

You can learn more about Google’s advertising practices here:
https://policies.google.com/technologies/ads

5. Data sharing

We do not sell your personal information.

We do not share your local game data with third parties except:

  • When required by law
  • When you use optional third-party services (such as ad networks) that process limited technical data as part of their service

6. Data retention and deletion

Local game and profile data remain on your device until you clear the App’s data, uninstall the App, or reset progress inside the App (if available).

Uninstalling the App generally removes locally stored data from that device.

7. Children’s privacy

Lumen CrossMath is a puzzle game suitable for a general audience. We do not knowingly collect personal information from children for sale or marketing. If you believe a child has provided personal information through a future online feature, contact us and we will take reasonable steps to delete it where applicable.

8. Security

We take reasonable steps to protect information stored by the App. However, no method of electronic storage is 100% secure, especially for data kept only on your device.

9. Changes to this policy

We may update this Privacy Policy from time to time. The “Effective date” at the top will be revised when changes are published. Continued use of the App after changes means you accept the updated policy.
