Cookies

The only cookies on this site are Google Analytics cookies (_ga and _ga_*, up to two years), and they are set only if you press Accept analytics. They tell visits apart so we can count them; Google acts as our processor and the data is not used for advertising. Change your choice at any time with Cookie settings at the foot of every page. Last updated 4 November 2026.

We do keep a few small preferences in your browser's local storage: units, theme, recent places and your analytics choice. They exist only because you chose them, and are never sent to us.
