What the rules say
- A missing 'reject' option on the first layer is a deficiency.
- 'Accept' and 'reject' must be equally visible.
- Non-technical cookies must not be used without consent.
- Cookie lifetimes must be proportionate to their purpose.
- The ÚOOÚ flags cookie information in a foreign language and missing details per cookie.
Enforcement examples
2023
The ÚOOÚ imposed a CZK 898,000 GDPR fine in a case that included non-essential cookies set without prior consent.

How PrivacyPill handles this
- Nothing optional runs before a choice. Google tags start with Consent Mode v2 set to denied; other scripts marked with data-pp-category wait until their category is allowed.
- Equal first-layer buttons. "Accept all" and "Reject non-essential" sit side by side with the same weight, and a settings button lets visitors withdraw consent at any time.
- Consent per purpose. Analytics, marketing and functional cookies can be allowed separately in the preferences panel.
- Languages. Czech isn't built in yet — rewrite the English texts in the customizer to show your own translation.
- Proof of consent. Every choice is logged pseudonymously with the banner version, exportable as CSV.
