7. Cookies and third-party services
The service uses storage strictly necessary for authentication, language preference and remembering your privacy choice. No advertising cookies or advertising profiling trackers are used.
Google Maps is necessary for the service: searching for a place provides the geographic coordinates and time zone without which the requested astrological calculations cannot be performed. When this feature is used, the browser contacts Google directly, which receives the IP address, technical browser and device information, entered search terms, selected coordinates and the date used to determine the time zone. No account data such as a name or email address is sent to Google by astro.day in this context. This processing is based on performance of the requested service and cannot be disabled separately.
With your consent, astro.day uses Google Analytics 4 to measure traffic and improve the service. Google processes pages viewed, navigation events, browser and device information, and approximate location derived from the IP address. Advertising settings and Google Signals are disabled. Addresses containing parameters or fragments are not sent. You can refuse or withdraw your consent at any time using the Privacy preferences link in the footer.
