Cookie Policy

Last updated: 5 July 2026

Strictly-necessary cookies — the small amount needed to keep you signed in and the site secure — are always on. Propura also offers optional analytics and personalisation/marketing cookies. These are off by default and are only ever set if you turn them on under Account → Privacy & Data; we set no analytics or marketing cookies without your explicit opt-in, and you can change your choice at any time.

Optional cookies (off by default). If you choose Analytics or All cookies under Account → Privacy & Data, we may set additional cookies: analytics cookies help us understand anonymised usage to improve Propura, and personalisation/marketing cookies tailor content. None of these are set while your choice remains Essential only — the default. Selecting Essential only again removes them.

We also use your browser's local storage for non-tracking preferences such as your selected display currency, your AI companion settings, and a record that you've seen the cookie notice. These stay on your device and are not used to track you.

You can clear cookies and local storage at any time in your browser settings; note that clearing the authentication cookie will sign you out.
