Links to other sites
When you follow a link to a government agency or another site, that site may set cookies of its own. Check its policy.
How to control cookies in your browser
You can block or delete cookies in your browser settings, and most browsers offer a setting that stops sites from tracking you. Google also offers a browser add-on that turns off Google Analytics. Blocking analytics does not change how the site works.
If we add cookies later
Before we add analytics, advertising or affiliate tracking, we will list each cookie here with its purpose and lifetime, and we will ask for consent first where the law requires it. See the privacy policy.

Frequently asked questions
Do I have to accept cookies to use the site?
The site works without them. Analytics cookies are set for visitors outside the European Economic Area, the United Kingdom and Switzerland. You can block them in your browser.
Will you add a cookie banner?
Only if we add tools that need consent, such as advertising. We would update this page first.
How can I check what a site stores?
