Privacy Policy

What we collect

We use first-party cookies for basic site features (for example visit counts and preferences). These are not used to sell personal data. You can clear cookies in your browser at any time.

Google AdSense

We use Google AdSense to show advertisements on some content pages (thesaurus articles and similar). AdSense may use cookies and similar technologies to serve ads based on your prior visits to this and other websites. Google’s use of advertising cookies enables it and its partners to serve ads based on your visit. You can opt out of personalized advertising by visiting Google Ads Settings.

Publisher ID: ca-pub-7080625593207732. Full-sky map pages (home, heliocentric, constellations) do not load AdSense.

Amazon Associates

AstroAlgos is a participant in the Amazon EU Associates Programme. Product links (for example telescopes and binoculars on Amazon.fr) use associate tag teleguide-21. We may earn a commission from qualifying purchases at no extra cost to you. Amazon may set its own cookies when you follow those links.

Analytics

We do not currently run a separate third-party analytics suite beyond what AdSense or the hosting provider may collect for operational purposes. If that changes, this page will be updated.

Payments (Donate)

Donations are processed by PayPal. We do not store your payment card details on AstroAlgos servers. PayPal’s privacy policy applies to those transactions.

Your choices

You can block or delete cookies in your browser, use Google’s ad settings for personalized ads, and ignore or dismiss affiliate suggestions on sky map pages (stored in localStorage on your device).
