How can we help?

Find the right place for product questions, privacy requests and account management.

Product support

Tell us what happened, the device you use and your app version. Screenshots are useful, but never send a password or sign-in code.

Request deletion of your MathChallenge account and associated personal data through our dedicated page.

Understand what information MathChallenge uses or contact us to exercise a privacy right.

Check your connection, update MathChallenge, close and reopen the app, and verify that you are signed into the expected Google or Apple account.
