What cookies we use
A cookie is a small file your browser stores on your device. We use cookies for two reasons:
- Essential — to keep you signed in and the service secure. These are always on.
- Analytics — to understand which features get used so we can improve them. Turn off anytime.
We do not use advertising or cross-site tracking cookies. We do not sell data to advertisers.
