In short: one cookie keeps you signed in. A few settings are remembered in your own browser. No analytics, no advertising, no tracking, so there is no cookie banner to click away.
Cookies

These are strictly necessary for a service you asked for, so the law does not require consent for them.

Outside services
The maps and the planner load map tiles, place search, weather and elevation directly from those providers (listed in the privacy policy, section 3). We do not let them set cookies through our pages; they see your IP address like any website you visit.
Removing them
Signing out removes the session. Your browser's settings can clear the rest for this site at any time.
If we ever add statistics to learn which features are used, we will choose a method without cookies and without personal profiles, or ask for consent first, and update this page before it starts.
