Privacy Policy

Tonight's Sky does not require an account, login, or personal information to use. The site fetches moon phase data from a third-party astronomy API and stores that day's result in your browser's local storage so the page loads quickly on repeat visits; this data never leaves your device and is not linked to you personally. Like most websites, this site may work with third-party advertising partners who use cookies or similar technologies to display ads and measure performance; these partners may collect anonymized data such as browser type and general location in accordance with their own privacy policies. We do not sell or share any personally identifiable information. If you have questions about this policy, you can reach out through the site's GitHub repository.
