Cookies
This page explains how the website www.zaden.cz works with browser storage and cookies.
1. Nothing runs without your consent
The za:den website uses third-party measurement and advertising tools: Google Analytics 4, Google Ads and the Meta (Facebook) Pixel. All of them are switched off by default. They are activated only once you give consent in the cookie banner — until then no analytics or advertising cookies are stored and no data about your behaviour on the site is sent to these tools.
2. What the site stores even without consent
This is essential for running the site and none of it leaves za:den:
- ✦Your choice in the cookie banner (localStorage, key zd-consent) — so the banner does not ask again on every visit. It holds only whether consent was given or refused, plus a version and a date.
- ✦A theme preference (localStorage, key zd-theme) — to remember light or dark mode.
- ✦The administrator login session (Supabase Auth) in the /admin area — it does not affect regular visitors.
3. What starts after you give consent
- ✦Google Analytics 4 — cookies _ga and _ga_*, measuring traffic and on-site behaviour. Operated by Google Ireland Limited.
- ✦Google Ads — cookies _gcl_*, measuring conversions from advertising campaigns. Operated by Google Ireland Limited.
- ✦Meta Pixel — cookie _fbp, conversion measurement and remarketing. Operated by Meta Platforms Ireland Limited.
Once consent is given, data about your visit is passed to these companies. They are independent controllers and handle the data under their own policies.
4. Withdrawing consent
You can change or fully withdraw your consent at any time via the “Cookie settings” link in the footer of any page. The cookie banner opens again and you can choose differently. The change takes effect immediately — there is no need to clear anything in your browser. Withdrawing consent does not affect the lawfulness of processing carried out before the withdrawal.
