This site does not require accounts or sign-ups, and has no forms that collect personal information like your name or address.

Analytics

This site uses Vercel Analytics and Speed Insights to understand aggregate traffic and page performance. These tools do not use cookies and do not track you individually across sites.

This site also uses Google Analytics to understand how visitors use the site. Google Analytics uses cookies to distinguish visitors and collects information such as pages visited, device type, and approximate location. You can opt out of Google Analytics tracking by installing the Google Analytics Opt-out Browser Add-on.

Advertising

This site may display ads served by Google AdSense. Google and its partners may use cookies or similar technologies to serve ads based on your prior visits to this or other websites. You can opt out of personalized advertising by visiting Google Ads Settings or aboutads.info/choices.

Local storage

Exercises run entirely in your browser. Settings you adjust (such as speed, size, or color) may be kept in your browser's local storage on your device so they persist between visits. This data stays on your device and is never sent anywhere.
