This Cookie Policy explains what cookies are, which cookies folio uses, and how you can control them. This policy should be read alongside our Privacy Policy.
What Are Cookies?
Cookies are small text files that a website stores on your device when you visit. They help the website recognise your device on future visits, remember your preferences, and keep you logged in. Cookies set by the website operator are called "first-party cookies"; those set by other services are "third-party cookies".

Analytics
We record anonymised page view counts internally to understand Service usage. No cookies are used for this, and no third-party analytics tools (such as Google Analytics) are used.
No Advertising Cookies
We do not use advertising or tracking cookies. No data is shared with advertising networks or social media platforms.
Managing Cookies
You can control and delete cookies through your browser settings:
Disabling essential cookies will prevent you from logging in. To clear your theme preference, open your browser's developer tools (F12), go to Application → Local Storage, and delete the mary-theme and mary-class entries for this site.
Changes to This Policy
We may update this policy when we change the cookies we use. The "last updated" date reflects the most recent revision.
