Cookies
We set zero tracking cookies. This page explains the one thing we do store in your browser and why.
What we set
Exactly one flag in sessionStorage: oc_annc = "1". It remembers that you dismissed the announcement bar at the top of the page, so it does not reappear on every navigation inside the same tab. It is cleared when you close the tab. Nothing else is stored.
What we do not set
- No analytics cookies (no third-party trackers).
- No advertising cookies (we do not advertise).
- No session cookies for identification (we have no accounts).
- No third-party pixels, no lookalike audiences, no re-marketing tags.
Third parties on this page
Two: the web font provider that serves the display fonts, and the OpenStreetMap tile server used on the about page. Both may set their own cookies when they serve their assets — we do not control those. If you block third-party cookies entirely, the site still works; the map may show a fallback.
Payment gateway cookies
When you open the payment link from the reply email, you leave this site and land on a payment gateway. That gateway sets its own cookies as part of its checkout flow. Those cookies are governed by the gateway's own policy, disclosed inside the payment page.
