What cookies are

A cookie is a small file that a website stores in your browser to remember something from one visit to the next. This policy also covers similar technologies, such as the browser’s local storage.

What we use and why

Technical cookies don’t require your consent, because without them the site can’t work the way you ask it to (for example, to keep you signed in if you log in to your account). If you never sign in to an account, none of the session cookies are stored. Analytics and advertising cookies are only activated if you accept them.

We don’t show ads yet, but the Google AdSense code does load on every page, because Google needs it to review the site. If you don’t accept advertising, we ask Google not to personalize it; if you accept it, Google may store the cookies in the table. We also don’t use any analytics tools yet. When we turn one on, we’ll add it to this table and ask for your consent again.

How to accept, reject, or change your mind

On your first visit, you’ll see a notice with three buttons: “Accept”, “Reject”, and “Configure”. Continuing to browse does not count as accepting. You can change your choice at any time from the “Cookie settings” link in the footer.

You can also delete cookies from your browser: Chrome, Firefox, Safari, or Edge.

International transfers

Google may process data outside the European Union. It explains this in its privacy policy. The rest of how we process your data is explained in our privacy policy.
