Cookies: which ones, why, how long.
We use cookies and browser storage. The necessary ones always work; analytics and advertising only if you accept them in the notice. You can change your choice at any time with "Cookie settings" in the footer.
Necessary, always on
- hh_cookies (ours, 13 months): stores your cookie choice.
- hh_interno (ours, one year): only the HH team switches it on, so their visits are left out of the statistics.
- Session storage (ours): remembers whether you have seen the home page intro and the properties you are browsing. Cleared when you close the browser.
- Local storage (ours): keeps the properties you mark, if you use that feature.
Analytics, with your consent
- Google Analytics (Google): _ga and _ga_*, up to two years. They measure which pages get read.
- Source campaign (session storage, ours): records which ad or site brought you here, so we know which campaign led to your message.
Advertising, with your consent
- Google Tag Manager and Google Ads (Google): _gcl_au, 90 days. They measure whether an ad led to a contact.
- Meta Pixel (Meta): _fbp, 90 days. It measures our ads on Facebook and Instagram and lets us show them to you.
