Privacy overview

Topla Kuća uses cookies so the site, the calculator and the cart work properly and so we can see which pages are useful to our customers.

Necessary cookies are always on — without them the cart, forms and language switching do not work. Everything else is your choice and can be changed at any time.

Necessary

These cookies handle the basics: your language, the cart and checkout, sending an enquiry, spam protection and remembering your cookie choice.

The site cannot work without them, so they cannot be switched off.

Analytics

Google Analytics and Microsoft Clarity show us how many people visit the site and which pages they read. The data is anonymous — we cannot tell who you are.

With your consent we also remember where you came from (search, an AI assistant, social media or an ad) and which pages you viewed, and pass this along with your enquiry so we know how you found us. This uses the cookies wpa_s and wpa_on for up to one year; they are not shared with anyone.

If you switch this off, nothing changes for you; we simply will not know which pages were helpful.
