Terms of use

Effective 3 October 2026. MATHOJI is provided by Mathoji.com. Contact [email protected] with questions.

Playing and sharing

Use MATHOJI for personal puzzle play. Do not interfere with the service or send unsolicited bulk invitations. You choose recipients and confirm sending through your messaging app.

Availability and saved games

The app creates no player account. Progress is saved on your device or browser, without MATHOJI cloud sync. Network interruptions can affect published puzzles and ads. Clearing storage, uninstalling or device changes can remove saves. We work to keep the service available but cannot guarantee uninterrupted access or recovery of deleted local data.

Third-party services

Advertisements, app stores and messaging services are operated by their respective providers. Optional rewarded-ad benefits are applied when the ad service confirms completion. Advertising does not promise financial rewards.

Your choices

Our privacy policy explains device storage, optional contacts, reminders and advertising. You can delete saved performance in Settings.

Changes and applicable rights

We may change features or these terms as the game develops. These terms do not exclude rights or remedies that cannot be excluded under the law applicable to you.
