„Používame cookies… na účely personalizovanej reklamy…"

✅ Accept all   ❌ Reject all   ⚙️ Settings

UI recommendations

• Banner template selection — when Consent Mode is enabled, the CMP interface should recommend a Google-compliant banner template.
• Automatic compliance features — with Consent Mode enabled, the following activates automatically:
  • a personalised advertising notice in the banner text,
  • a link to Google's privacy policy,
  • the correct Consent Mode default commands,
  • all 7 Consent Mode consent types. Governed by consent (by default denied) 4 advertising/analytics ones: ad_storage, analytics_storage, ad_user_data, ad_personalization (the last two were added with Consent Mode v2). The remaining 3 are by default granted: functionality_storage, personalization_storage, security_storage.
