Cookie Policy

What are cookies?

Cookies are small text files that are placed on your device when you visit a website. They are widely used to make websites work, or work more efficiently, as well as to provide information to the site owners.

How we use cookies

We use only a small number of cookies on this website:

• Essential session cookie (wt_session) — this is a strictly necessary, encrypted, HttpOnly cookie that keeps you logged in while you browse. It contains a random session identifier and no readable personal information. We do not store your Supabase access or refresh tokens in the browser; those are held on our server.
• Cookie preference (wt_consent) — this remembers whether you have accepted or declined optional analytics cookies. It is set only after you make a choice in the banner.
• Vercel Web Analytics and Speed Insights — these are loaded only if you click "Accept Analytics". Vercel Analytics does not use third-party cookies; it collects anonymised, aggregated data such as page views using a one-day hash derived from the incoming request. Vercel Speed Insights anonymously reports Web Vitals and other performance metrics to help us understand how quickly pages load; it does not use cookies or identify individual visitors. You can read more in the Vercel Web Analytics privacy policy and Vercel Speed Insights privacy policy.

Managing your cookie choices

When you first visit the site, you can choose to accept optional analytics cookies or use only essential cookies. You can update your choice at any time by clearing the "wt_consent" cookie in your browser settings, which will cause the banner to appear again on your next visit.
