What is a cookie?

A cookie is a small text file a website stores on your browser. We also use a few similar technologies (localStorage entries, web beacons in transactional emails) — for brevity this policy treats them all as “cookies”.

How to control cookies

When you first visit the site we ask whether you accept analytics and functional cookies. You can change that decision at any time:

  • From your account settings under Privacy → Cookie preferences.
  • By clearing cookies in your browser — we will ask again on your next visit.
  • By using your browser's Do Not Track setting; we honour it as a signal to disable analytics cookies.

Strictly-necessary cookies cannot be disabled — without them the site cannot function. We never set marketing cookies, and we have no plans to add them.

Third-party cookies

Stripe sets its own cookies on the pricing and checkout pages for fraud detection. See Stripe's cookie policy for details. We do not embed advertising networks, social-media pixels, or session-replay tools.
