Cookies and browser storage
We use one cookie, to keep you signed in, and a little browser storage to remember how you like the app. There are no advertising or analytics cookies, and nothing that follows you to other sites. All of it is strictly necessary for the service you asked for, so we do not ask for consent.
The cookie
| Name | What it does | How long it lasts |
|---|---|---|
__Host-session |
Keeps you signed in, and carries the token that stops another site submitting forms as you. | Until you sign out, or after 30 days without a visit, and never longer than 90 days |
Browser storage
The app keeps a few small settings in your browser's local storage. They are read by the page and never sent to us.

Other services
The map tiles are loaded from the services the privacy notice lists. Your browser sends them its IP address when it fetches from them. We do not use any of them for advertising or analytics. Everything else the pages load, the charts, scripts and typefaces included, is served by us.
Clearing them
Signing out removes the cookie and the storage that names your tracks, polars or boats. Your browser's settings for this site can clear the rest. Without the cookie you cannot stay signed in.
