This page summarises the cookies and analytics tools used on ondraweb.cz, what they are for, and how to revoke your consent to their use at any time.
What I use
- Google Analytics 4 (GA4) — anonymous traffic statistics that show how many people visit the site, where they come from, and which sections engage them.
- Microsoft Clarity — heatmaps and session recordings (with anonymised content) that help spot where visitors struggle to find what they are looking for.
I do not use any advertising cookies or ad targeting. In GA4, the advertising consents (ad_storage, ad_user_data, ad_personalization) remain permanently set to denied.
What I measure
- Traffic and sources (where visitors come from, how many pages they view, how long they stay).
- Interactions with the main calls to action — clicks on the call-to-action button, the phone number, opening the form, submitting an inquiry.
- Session recordings (Clarity) — anonymised video capture of cursor movement and clicks so I can spot places where visitors get lost.
Retention period
- “Accept all” consent — stored in the browser (
localStorage) for 365 days, after which you will be asked again. - “Decline” — stored for 180 days; during this time the banner will not ask again and no analytics cookies are set.
- GA4 cookies (
_ga,_ga_*) — typically 2 years (only if you grant consent). - Microsoft Clarity cookies (
_clck,_clsk,MUID,CLID) — as configured by Microsoft (typically 1 year).
How to revoke consent
If you want to revoke your consent, click the button below. It clears the stored consent and any GA / Clarity cookies, and after reloading the page the banner will reappear.
Alternatively, you can clear cookies for the ondraweb.cz domain manually in your browser settings.
