Cookie & Storage Disclosure
A plain-language description of essential browser storage used by the application.
Local storage
The application uses local storage for guest project autosave, tutorial completion, interface preferences, and feedback cooldown state. These records support requested features and are not advertising cookies.
Authentication storage
When you choose Google Sign-In, Google and Firebase may use cookies or browser storage needed to authenticate you, prevent abuse, and maintain your session.
Analytics and performance
We use Vercel Web Analytics and Speed Insights to understand page visits and performance, such as page views, browser/device performance metrics, and general usage trends. We use this information to improve YDK Simu Lab. We do not use it to collect passwords or private experiment content.
Your controls
You can clear local records through your browser settings, continue as a guest, sign out, delete cloud projects, or delete your YDK Simu Lab account data. Blocking essential storage may prevent autosave or sign-in from working.
