Cookies policy
Short version: we don't track you. Long version, here.

No tracking, no marketing
Sidellia uses no tracking cookies, no advertising cookies, no third-party analytics. No Google Analytics, no Meta Pixel, no TikTok Pixel, nothing similar. We don't follow you around the web.
Essential technical cookies
We use a technical security cookie (cas_csrf), strictly necessary to protect forms against request forgery. It does not identify users or track your browsing.
If you also sign in with your email, our authentication provider (Supabase Auth) sets another technical cookie to remember your session, also strictly necessary, expiring when you sign out or after a period of inactivity. We use no other cookies.
How to disable
You can block or delete cookies from your browser settings. If you block the essential cookie, sign-in will not work, but you can still compute natal charts (that happens client-side, without cookies).
No third-party trackers
We do not embed social network widgets, "like" buttons, or advertising pixels. Images and fonts are served from our own servers, with no third parties tracking your browsing.
