Cookie policy

The small files and browser storage Maxwell Books uses, and why.

Last updated Oct 26, 2026

Only what's needed

We only use cookies and browser storage that are needed to sign you in, keep your account secure and remember a choice you've made. We don't use any for analytics, advertising or tracking, and we don't let other companies put tracking cookies on our site. Because these are all needed for the site to work, there's nothing to turn off.

What we use

  • Sign-in cookies (names starting with "sb-"): keep you signed in. Set by Supabase, our sign-in provider. They last until you sign out or your sign-in ends.
  • Activity cookie ("pl-seen"): the time we last saw you active, so we can sign you out after 30 minutes without activity. Lasts up to 13 hours.
  • Activity time in your browser's storage ("pl-last-active"): shares your last activity between your open tabs for the same reason. Stays until you sign out or clear your browser data.
  • Cookie notice ("kl-cookie-notice", in your browser's storage): remembers that you've seen the cookie notice, so it doesn't keep appearing.
  • Bot check: once we turn on Cloudflare Turnstile on the sign-in and sign-up pages, Cloudflare may use its own storage to check you're a person.

Your choices

You can delete cookies and site data in your browser's settings at any time. If you block them, you won't be able to sign in.
