Privacy Policy
This policy explains what information Blue Hour Calculator may use and how that information supports the calculator and content experience.
Location information
The calculator may ask your browser for location access so it can estimate natural light times. Browser location access is optional. If you use manual latitude and longitude input, the calculation can run without browser geolocation permission.
Cookies, analytics, and advertising
This site may use analytics and advertising products in the future to understand usage and support the site. These services may use cookies, IP addresses, device information, or similar technologies according to their own policies and browser settings.
If Google advertising products are added later, this policy will continue to disclose that Google and its partners may use cookies or similar identifiers to serve and measure ads.
