Cookies & device storage

Short version: we store the minimum needed to sign you in and remember your preferences. There are no analytics cookies and no advertising cookies. Page views are counted without cookies, and nothing follows you to other sites.

Essential cookies

These are required for the app to work and can’t be switched off, which is why we don’t show an accept/reject choice.

What we don’t do

No analytics or usage-tracking cookies. Page views are counted without them
No advertising or cross-site tracking
No third-party cookies, except embedded videos you tap to play (below)
No selling or sharing of your data

Embedded tutorial videos

Workout exercises can include a “Watch tutorial” video hosted on YouTube. Nothing from YouTube loads until you tap it. When you do, the video plays through YouTube’s privacy-enhanced mode (youtube-nocookie.com), which is designed not to track you for personalization, but it is still a Google service and subject to Google’s privacy policy. If you never tap a video, nothing is ever requested from Google.

Managing them

Logging out removes your session cookie. You can clear everything else at any time through your browser’s site-data settings. The app will simply ask you to sign in again and re-ask your preferences.
