No sign-up
When an explorer begins, our server issues a random, pseudonymous learner id that is stored on that device and acts as its account reference. We never ask for an email address, phone number, password or full name.
Privacy
We collect almost nothing. Here's the full list.
MapMyMath is built for children, so the simplest privacy policy is the honest one: no sign-up, no emails, no ads and no selling data. This page is everything we store and why.
What we store
Against that learner id: an explorer nickname, school year, chosen avatar and the maths itself—questions answered, progress, stars, reviews and in-game rewards. We also keep a small first-party learning-event history: when quests start and finish, their skill, accuracy and duration.
No ads, no data sales
We show no advertising, sell no data and run no third-party marketing trackers. There are no leaderboards and no public profiles, so a child's progress is never shown to anyone else.
Error reports
On the website, non-learner software errors may be sent to Sentry so we can fix them. Personal-information collection, session replay and performance tracing are disabled, and learner API errors are excluded. The Android and iOS apps do not send Sentry crash reports. Firebase Messaging may process limited diagnostic and operational information needed to deliver optional reminders.
Reminders (app only)
In the mobile app, if notifications are allowed, Apple Push Notification service and Google Firebase Messaging process a device notification token so we can send low-frequency practice reminders. We store that token against the learner id. Turn notifications off in device settings and reopen the app to remove our saved copy; deleting learner data also removes it immediately. Firebase's processing is described in Google's Firebase privacy information.
Use and acquisition data
For product analytics we store coarse information only: the referring website's host, device class (phone, tablet or desktop), app actions and quest totals. These records use the learner id so they can be deleted with the learner. Standard server logs may contain an IP address, request time and requested page for security and reliability; they are not joined to learning progress and are discarded within 30 days.
Linked, but pseudonymous
Progress, product interactions and any reminder token are linked to the random learner id so the app can remember and personalise the experience. We do not know the learner's real-world identity unless somebody chooses to put identifying information into the nickname field, which we ask them not to do.

Good to know
No real money in the game
Coins and chests are earned by doing maths. Nothing in the game can be bought with real money, so there is no payment data to collect.
Deleting your data
Learner data and progress can be permanently deleted from Settings → Delete my data. After the grown-up check and confirmation, we delete the learner record and its linked learning events from our server and remove the pseudonymous id from the device. Full steps and what's kept.
