This Cookie Policy explains how kortbase uses cookies and similar technologies.
What cookies are
Cookies are small files stored on your device that help the site work and let us measure usage.
Essential cookies
Required for the site to function, for example, remembering your language preference.
Analytics cookies
Help us understand how the site is used so we can improve it. These are only set with your consent.
Managing cookies
You can decline non-essential cookies in the consent banner. Change your choice at any time using the Cookie settings link at the foot of any page.
Product analytics and session replay (coach portal)
On the signed-in coach portal we use PostHog cookies to measure product usage and to record masked sessions for debugging and product improvement. These run under our legitimate interest rather than through the consent banner, because the portal is an internal tool for signed-in coaches. You can object to this processing by contacting us.
Live chat cookies
The chat on our website, provided by Crisp, stores cookies whose names begin with crisp-client/ on your device, along with similar local storage. They keep your conversation attached to your browser, so a chat you started continues on the next page and on your next visit instead of opening a new conversation each time. They are set when the chat loads, because the chat cannot work without them, and they are not used to track you on other websites. They expire after six months, renewed each time you come back. You can delete them in your browser settings, and the chat will then start a new conversation.
