Cookies & device storage

Short version: we store the minimum needed to sign you in and remember your preferences. There are no analytics cookies, no advertising cookies, and no third-party trackers anywhere in the app.

Essential cookies

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

Lifetime: Until you log out (or it expires)

Protects sign-in forms against cross-site request forgery attacks.

On-device preferences (localStorage)

Stored only in your browser — never sent to our servers.

Theme preference
Remembers your Light / Dark / System choice.
Install suggestion
Remembers that you dismissed the “add to home screen” tip.
Cookie notice
Remembers that you’ve seen this notice, so we don’t nag.

What we don’t do

No analytics or usage-tracking cookies
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.
