Editing, compilation for preview, and the simulator run entirely on your device, in your browser.
Projects are saved only in this browser’s storage. We do not back up or sync your workspace to the cloud. Signing in on another computer, browser, or browser profile will not bring your projects with you.
Clearing this site’s browser data or using private browsing can erase your projects. Use Download ZIP regularly to keep a backup and take your project with you.
Cloud builds send build inputs to BuildCloud when you request a build. They do not back up your editable workspace.
