We do not use cookies for advertising, retargeting, or behavioural profiling.

- View and delete individual cookies.
- Block all cookies from specific sites.
- Be notified when a new cookie is set.
Refer to your browser's help documentation for instructions. Blocking functional cookies may reduce the personalisation features of the Platform.

Our authentication provider (Clerk Inc.) and error monitoring provider (Sentry Inc.) may set their own cookies. These are governed by their respective privacy policies and are used solely to deliver their services to us. We do not share personal data with advertising networks.
6. Changes to This Policy
We may update this Cookie Policy as our technology or legal requirements change. When we do, we will revise the “Last updated” date above. Continued use of the Platform after changes are published constitutes acceptance.
