Cookies and similar technologies
Last updated: May 26, 2026
We try to use as few cookies as possible. Our analytics is cookieless (Plausible) — no cookie banner needed. The rest are strictly necessary technical cookies that keep login and user preferences working.
1. Analytics — Plausible
Traffic is measured via Plausible Analytics, a privacy-friendly tool that stores no cookies and does not track users across sites. To deduplicate unique visitors within a single day, a daily-rotating hash of IP + user agent is used — never paired with any identifier.
Per current European guidance (CNIL, ICO), Plausible does not require cookie consent because it stores no cookies.
2. Authentication — Auth.js (session cookie)
Once you sign in, we store a single cookie named `authjs.session-token` (or `__Secure-authjs.session-token` in production). It keeps your session secure between requests.
Attributes: HttpOnly (not readable from JavaScript), Secure (HTTPS only in production), SameSite=Lax (CSRF protection), expires after 24 hours.
Legal basis: legitimate interest (GDPR Recital 30) — you cannot sign in without it. This is not a tracking cookie.
3. Language preference — NEXT_LOCALE
When you switch language (CS ↔ EN), we store your choice in a `NEXT_LOCALE` cookie so your next visit starts in the right language. Expires after 1 year.
Contents: only a 2-letter code (`cs` or `en`) — no personal data.
4. 18+ content visibility — pp_show_adult
If you are not signed in and you opt in to see SEX category events (18+) via the header toggle, we set a `pp_show_adult` cookie with the value "1". Expires after 30 days.
Used only for server-side filtering of the event catalogue — no tracking, no third-party sharing.
5. No other cookies
We do not use cookies for advertising, marketing, profiling or cross-site tracking. No Google Analytics, Facebook Pixel or similar.
External players / iframes (e.g. the OpenStreetMap map on venue detail pages) may set their own cookies — we cannot control that. If this bothers you, you can block them in your browser; the map simply won't render.
6. How to disable cookies
You can delete or block cookies at any time in your browser settings. Note: blocking session cookies means you cannot sign in and some parts of the site (favorites, /account, /promoter) won't work.
