Cookies Policy
Last updated: 27 May 2026
1. What cookies are
Cookies are small text files a website stores on your device. They allow a site to remember something between visits, like a login or a language preference. Some cookies are needed for the site to work; others are used to track behaviour across pages or across the web.
2. What we currently use
Mercuriosity is deliberately light on cookies. As of the date above, we use no analytics cookies, no advertising cookies, and no third-party tracking cookies. The only browser storage we use is one entry in localStorage that remembers your cookie consent choice, so you do not see the banner on every visit.
| Name | Type | Purpose | How long |
|---|---|---|---|
mc-cookie-consent |
localStorage (not a cookie) | Remembers whether you accepted or declined non-essential cookies, so the banner does not reappear. | Until you clear browser storage or use the reset button below. |
3. What may happen when you click through to a third party
We embed nothing tracking-related on the site itself. But when you click a link that takes you off mercuriosity.eu, that destination sets its own cookies under its own policy. The most common cases:
- Substack — when you click through to read or subscribe to The Operating Table, Substack sets cookies on its domain. See substack.com/privacy.
- LinkedIn — same applies to the LinkedIn link in the footer. See LinkedIn privacy policy.
4. What our service providers may do
- Vercel (our host) may set technical cookies needed for routing and security. These are essential to serving the site. vercel.com/legal/privacy-policy
- Supabase (used only by the Evidence Chain Translator) stores anonymous form submissions. It does not set tracking cookies on your device.
5. If we add analytics later
If we ever add analytics (Plausible, Fathom, or similar), we will update this page first, and the cookie banner will be wired to honour your choice. Analytics will not load unless you accept.
6. Change or reset your choice
You can clear your stored consent choice and the banner will reappear on your next page load.
Cleared. Refresh the page.You can also manage cookies through your browser settings. Most browsers let you block third-party cookies, clear all cookies, or be notified before one is set. See aboutcookies.org for instructions per browser.
7. Changes to this policy
If we change what cookies we use, we update the "Last updated" date and the table above. For material changes (for example, adding analytics), the banner will reappear so you can make a new choice.
