Third parties

Only if you accept: the Inter font is loaded from Google Fonts, so your browser contacts Google. If you decline, nothing is requested from Google. See Google's privacy policy at policies.google.com/privacy. There are no other third parties, and our own scripts and images come from our own domain.

Your choices

You can change your font choice at any time with "Cookie settings" in the footer of the home page, and clear this storage in your browser settings. Logging in will not work without it. If we ever add anything optional, such as analytics, we will ask for your consent first and it will be off until you agree.
