Cookie Policy

A cookie is a small text file a website stores in your browser. It usually holds a short ID, not your personal information. Its job is to let the site recognise your browser on the next page load — otherwise you would be signed out every time you clicked a link.

Some are essential to the site working. Others are optional. Below is every one we use and which kind it is.

These make the site function. They cannot be switched off, because without them you could not sign in or stay signed in.

• Session cookies (set by Supabase, our auth provider) — keep you signed in as you move between pages. Cleared when you sign out.
• Security cookies — protect sign-in and forms against request forgery.
• Your cookie choice itself — so we stop asking once you have answered.

We use Vercel Analytics and PostHog to count page views and see which pages get used. Neither follows you across other websites or builds a profile of you, and we never record your screen.

Until you choose Accept all, PostHog keeps its visitor id in memory only and forgets it when you close the tab. Accept all lets it remember your browser in local storage, so a return visit is not counted as a new person.

No advertising cookies. No third-party tracking pixels. No cross-site profiling, and no selling or sharing your browsing to anyone.

This matters more than usual here: most of the people using Axiom are minors. Several state privacy laws restrict targeted advertising to known minors, and we do not run any.

The banner on your first visit lets you pick Accept all or Essential only. Your choice is stored locally, and we do not ask again unless you clear your browser data.

You can also clear or block cookies in your browser settings at any time. Blocking essential cookies means sign-in will stop working — everything you can browse without an account will still work fine.

If we add anything that sets a new cookie, this page gets updated and the date at the top changes.
