Privacy policy
Last updated:
Memath is a mental-math game. This policy covers the Memath app and its website, memath.app. It says what each of them does with your data. The short version: Memath has no account, no tracking and no ads, and your data stays on your device.
What the app stores
Memath stores this on your device only:
- Your progress: levels, stars, round results, “Endless” runs, streaks and statistics.
- The levels you create.
- Your settings: sound, haptics, start automatically, keypad layout, theme and language.
- A few app flags: whether you finished the tutorial, the version and date of the first launch, and the date of your last free “Endless” run.
This data is kept in the app’s local storage. It never leaves your device. We do not receive it and we cannot see it. Deleting the app deletes it. “Settings” has a “Reset progress” action that deletes your progress.
What the app does not do
- No account or sign-in.
- No analytics, tracking or advertising identifiers.
- No ads.
- No crash reporting service.
- No access to your contacts, photos, location, camera or microphone.
Purchases
The one-time unlock is sold through the Apple App Store or Google Play. Apple or Google handles the payment and receives your payment details. We never see them. The app uses RevenueCat to check whether the purchase is active. RevenueCat receives an anonymous app user ID and your purchase information from the store, to confirm the unlock and restore it on your other devices or after a reinstall. It does not receive your name or email address from us.

The website and the Support form
The website memath.app sets no cookies and loads no third-party scripts. It uses only Cloudflare’s basic service data for security and operation, not analytics or advertising. Its fonts and images are served from the site itself.
The site is hosted on Cloudflare. Cloudflare may process basic technical data, such as your IP address, to provide and secure the site. We do not use this data to identify you or track your activity. See the Cloudflare privacy policy.
The Feedback form on the Support page is the only part of the site that sends data elsewhere, and only when you press Send. It sends your message and your topic, and, if you fill them in, your email address, app version and platform, to Web3Forms, which emails them to the publisher. The form does not ask for your name or age, and the email field is optional: without it we cannot reply.
We keep feedback emails for up to 12 months after the last reply, then delete them. To have your messages deleted sooner, email support@memath.app.
Children
Memath is not designed for children under 13 and does not knowingly collect data from anyone.
Changes
If this policy changes, the new version is published at this address with a new date.
