# 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.
