Data on this device
Language preferences and brush presets are stored in your browser. A solo drawing autosave is stored in IndexedDB. These records belong to this browser and device. You can delete them by clearing this site’s browser data. Download your drawing first.
Shared rooms
Joining a room creates an anonymous technical identity in Supabase to verify permissions. Nicknames, membership, permissions and activity timestamps are processed on the server. You do not need to enter an email address.
Drawing actions, imported images, chat and cursor positions are transmitted to room participants. Anyone with the room code can join; avoid sharing sensitive information. Messages may be temporarily processed and retained by Supabase Realtime. The service does not provide a permanent artwork archive.
Service providers
Cloudflare serves the site. Supabase supports collaboration, Google Fonts supplies fonts and CDN providers deliver JavaScript files. These connections transmit technical information such as IP addresses and browser details to providers. If Cloudflare analytics is enabled on the deployment, visit measurements may also be processed.
Your controls
Clear local records through browser settings and end a shared session by leaving the room. Clearing local data does not automatically delete providers’ technical logs or anonymous identity records.
