Summary in one sentence
We use strictly necessary cookies for login, the server-side limit on public asset details and payments, and basic cookieless analytics (Vercel Analytics, Vercel Speed Insights). The referral cookie is stored only after separate consent and is used only to attribute a referral. We use no cookies for ad targeting, remarketing or profiling.
What cookies are and why they are needed
Cookies are small text files that a website stores in your browser. Without the necessary cookies the Server could not keep you logged in between pages and the payment gateway would not work. Under the ePrivacy Directive and Section 89 of Czech Act No. 127/2005 Coll., on Electronic Communications, strictly necessary cookies do not require separate consent.

Analytics without cookies
To measure the Server's traffic and performance we use Vercel Analytics and Vercel Speed Insights. Both tools work without storing cookies and without identifying users across websites. They process limited technical request data and aggregated metrics such as pages viewed, the approximate technical environment and Core Web Vitals. We do not use them to build an advertising profile of any visitor.
Data from these analytics is processed by Vercel Inc. under its privacy terms; any transfer outside the EEA follows an appropriate mechanism under the GDPR.
