Cookie Policy

How GLM 5.3 Online uses cookies and similar browser technologies, and the choices available to you.

Last updated August 23, 2026

What cookies are

Cookies are small text records stored by a browser. They can keep a signed-in session working, remember a preference, protect a form from abuse or help a service understand whether a page works as expected. Similar technologies can include local storage and short-lived security tokens.

How we use them

  • Essential cookies support authentication, account security, checkout continuity and other features required for the service to operate.
  • Preference cookies can remember choices you make so the interface behaves consistently on a later visit.
  • Performance or analytics cookies may provide aggregated information about page use, errors and responsiveness so we can improve the service.
  • Payment, authentication and infrastructure providers may set cookies that are necessary to complete the service you request. Their handling is governed by their own policies.

Your choices

Most browsers let you inspect, block or delete cookies. Blocking an essential cookie can prevent sign-in, payment or security features from working. Where consent is required for a non-essential category, we will request it before using that category. Browser privacy controls do not remove information already processed under another lawful basis.

Retention and updates

A session cookie normally expires when the session ends. A persistent cookie remains until its stated expiry or until you delete it. We aim to retain each cookie only for the period needed for its stated purpose. We may revise this policy when our providers or product features change; the date above identifies the current version.
