Cookie Policy

Last updated: March 2026

This page explains what cookies this website uses, why, and how you can control them.

1. What are cookies?

Cookies are small text files stored in your browser when you visit a website. They help the site remember things like your preferences or understand how you use it.

2. Cookies this site uses

This site uses cookies only if you click "Accept" on the consent banner. If you reject or ignore the banner, no cookies are set.

When accepted, Google Analytics 4 sets the following cookies:

Cookie Purpose Duration
_ga Distinguishes unique visitors 2 years
_ga_* Stores session state and event data 2 years
_gid Distinguishes visitors within a 24-hour window 24 hours
_gat Throttles request rate to Google 1 minute

3. Local storage

This site also stores your cookie consent preference in your browser's local storage (key: cookie-consent). This is not a cookie — it's used solely to remember whether you accepted or rejected cookies so the banner doesn't appear on every visit.

4. Third-party cookies

This site does not use any advertising, marketing, or social media cookies. Google Analytics is the only third-party service that sets cookies, and only when you consent.

5. How to withdraw consent

You can withdraw your cookie consent at any time. Click the button below to clear your preference — the consent banner will reappear on your next page load.

You can also delete cookies manually in your browser settings:
