Cookie Policy · AskBooks

1. Categories we use

Essential cookies are required for the site to work — authentication, CSRF protection, language preference, consent state. These cannot be disabled.
Analytics cookies help us understand which features matter and where users get stuck. We use Google Analytics 4 with IP anonymisation and Google Signals turned off, plus PostHog with EU-region storage. These run only with your consent.
Marketing cookies measure which campaigns brought you to AskBooks. Off by default; only set when you explicitly opt in via the consent banner.

You can change your cookie preferences at any time:

Click the “Cookie preferences” link in the footer.
Adjust browser settings to refuse cookies — note that essential cookies are needed for sign-in.
Use browser-level Do-Not-Track / Global Privacy Control signals — we honour both.

Our iOS and Android apps don’t use HTTP cookies. They use platform-secure storage for session tokens and explicit advertising-identifier opt-outs.

We refresh this page when we add, remove, or change cookies. Material changes are notified via the consent banner re-prompt.
