Math Teasers is made for kids in grades 4 to 7, so we collect nothing about them. There are no accounts, no sign-up, no names, no emails, no photos and no location. We don't ask for any personal information, and we don't sell or share any.
Stars, stickers, days played and your settings (grade band, sound on or off) are saved in your browser's local storage on your own device. They are never sent to us. To erase them, open Grown-ups in the app and choose Reset progress, or clear this site's data in your browser settings.
Math Teasers does not use Google AdSense, Google Analytics, advertising cookies, or any other tracking or analytics tool. The app does not load scripts from other websites.
Between lessons we may show a small note about our own books and our other free apps. These are plain links we wrote ourselves, not ads from an ad company. A link only opens after a grown-up holds a button for two seconds. Those other websites have their own privacy policies.
The app is hosted on Netlify. Like any web host, it may keep standard server logs (such as IP address and the pages requested) for security and to keep the service running. We don't use those logs to identify children.
