ContentSketch currently uses essential browser storage needed to sign in and operate the app. We do not configure advertising or third-party analytics cookies.
Essential session cookie
The app sets a cookie named studio_session to recognize your signed-in session. It is marked HttpOnly and SameSite=Lax, and is marked Secure when served over HTTPS. The session expires after 12 hours. This cookie is necessary for the app’s account and workspace features.
Authentication provider storage
Firebase Authentication and your chosen sign-in provider may use browser storage or cookies while completing authentication. Provider-controlled storage is subject to that provider’s own privacy and cookie information.
Your controls
You can clear cookies and site storage in your browser settings. Clearing the session cookie will sign you out and may require you to authenticate again. Blocking essential storage may prevent sign-in or app features from working. For related details, see the Privacy Policy or contact us.
