Privacy Policy

The short version

Math Drill has no accounts, no sign-up and no chat. We do not ask for your name, email address or any other personal information, and your game progress never leaves your device.

Game progress

Your settings, history, skill progress, trophies and collection are saved in your browser's local storage under keys that start with "mathdrill". This data stays on your device and is not sent to us. You can delete it at any time with Settings → Reset All Data in the game, or by clearing this site's data in your browser. Progress does not move between browsers or devices.

Cookies

We may set a small cookie to remember the language you chose. We do not use advertising cookies or cookies that track you across other websites.

Hosting

The site is served by Cloudflare. Like any web host, Cloudflare processes technical data such as IP addresses and browser type to deliver pages and protect the site from abuse. We use this only for running the service.

Analytics

If we measure visits, we use privacy-friendly analytics that count page views in aggregate, without cookies and without building personal profiles.

Children

Math Drill is made for children and families. Because there are no accounts, no text entry beyond typing digits into the game, and no data collection, we do not knowingly collect personal information from anyone, including children under 13. If we ever add advertising or other features that change this, we will update this policy before they go live.

Changes

We will post any change to this policy on this page and update the date above.
