# Where are my backup data and images stored? Undo uses a class-leading database system for powering and securing backups. Related medias (images and files) are stored in a secure, cloud based object storage accessible via cdn.undoapp.io {% hint style="warning" %} *No sensitive information about customers or orders are ever saved.* {% endhint %} All object information including change history as well as related medias are instantly deleted if you choose to uninstall Undo. Going forward, Undo will offer a 30-day retention period before deleting your data in the event of an uninstall, allowing you to reinstall with all data intact, if the app was deleted in error. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
