This Cookie Policy explains what cookies and similar technologies Track My Bunny uses and the choices you have. By continuing to use the service you consent to our use of essential cookies.
Cookies are small text files placed on your device by websites you visit. They allow the site to remember information about your visit — such as your login session or language preference. Local storage is a similar browser technology that stores data locally on your device without an expiry date.
These cookies are required for Track My Bunny to function. They cannot be disabled.

| authjs.csrf-token | Protects sign-in and sign-out requests against cross-site request forgery (CSRF) attacks. | Cookie | Session |

When analytics consent is granted, Google Analytics (operated by Google LLC, USA) sets the cookies described in section 4. Track My Bunny has no control over third-party cookies.
