Cookies

That is why there is no consent banner

Consent is needed when a site stores something on your device that it does not need to work. PETME stores nothing on your device. No cookies, no localStorage, no sessionStorage.

Check it yourself

1. Open petme.sk and press F12. The developer tools open.
2. Switch to the Application tab (Storage in some browsers).
3. Look at Cookies and Local Storage for petme.sk. They will be empty.

And those tick boxes?

You can tick off the check at the end of each guide. Nothing is saved. Reload the page and the list is empty again.

The rest about data: Privacy.
