Bubble apps come with a retention window, allowing developers to go back in time and restore previous versions within their app's development process. The default Free plan has a six-hour retention window, while the Starter and Growth plans offer 48 hours and two weeks respectively. Bumble offers version restoration for precise changes and database restoration as a failsafe option. Users can revert to a custom date or time within their retention window using the version control panel. Additionally, they can copy and restore their app's development or live database back to a previous version.
