Your projects & your data

You are in full control of your data

Our tools do not store any information regarding your projects, connections or diagrams in the cloud. Everything you create and store stays with you.


You choose where to store each, of your projects. Our tools automatically create and update a list of your projects so that you have an easy way to reopen them. This list is also only stored on your device. The path is listed for each of the projects.

List of projects in Moon Modeler

To remove a project from the project list, click on the cross icon. This does not delete the project file itself, it just removes it from the list.

Remove an item from the project list

If you delete a *.dmm project file from the file system, information about the missing file will be displayed.

Database connections

When you create a database connection, the information is encrypted and stored on your device. Database connection information is not stored in the cloud or shared in any way.

Our tools list these connections and only do this so that you can reverse engineer the database structure again. In the case of Luna Modeler, these connections can be used for the Project Update feature.

If you plan to create a project from the database in a one-off way, you can proceed as follows:

  1. Create a database connection
  2. Click Connect and load existing database structure to create a new project.
  3. Delete the connection

Deleting a connection will delete the record completely.

If you need to set up a proxy to activate the commercial version, for example, you can specify the configuration in settings. The information will be encrypted and stored on your device.
