No user data is stored in our database, only the entire content of the document submitted via the "Save" button.
If you include personal data or that of others within the document, it will be stored as part of the document itself.
The admin, Gabu, has access to the database, which is necessary for the initialization and maintenance of the application.
We understand that this might be a concern, which is why we provide the option to store documents locally. (See /how-to-use for more information, including how to share a locally stored document with someone else.)
