These cookies are needed to provide the service you ask for, so they do not depend on your explicit consent. The session cookies are deleted when you sign out.
Other information kept in your browser
- Unsaved form content: so that what you type in the program, event and idea creation forms is not lost when the page closes (localStorage).
- Assistant conversation: so that the last message sent to the AI assistant is not lost if the page reloads (sessionStorage; deleted when the tab closes).
- Verification status: to remember that you sent a profile verification request (localStorage).
- Idea likes: a randomly generated identifier so that a public idea is not liked more than once from the same browser (localStorage); it is not linked to your identity.
Third-party content
When YouTube, Vimeo or Loom videos added to startup pages are shown, these providers may set their own cookies and receive your IP address; those cookies are subject to the providers' own policies. Page fonts are loaded from Google Fonts, which passes your IP address to Google, but Google Fonts does not set cookies.
Managing cookies
You can delete or block cookies and local storage in your browser settings. If you block the session cookies you will not be able to sign in; if you delete the language cookie, your language preference is set again on your next visit.
Changes
If we start using a new cookie or change the purpose of an existing one, we update this page; the date of the update is shown at the top. For more information see the Privacy Policy and the Personal Data Protection Notice.
