The ULTIMATE Catalogue processes and stores data locally. All user input is stored inside your browsers local storage and is never sent back to the server. All website resources act as static components without any server feedback. Therefore, you are in full control over your own data. The Data Management options allow you to import, export, or completely delete all your stored data. The following video explains how your data is processed.
Google Drive Integration
During the first setup the website creates a folder called catalogue.ac on your Google Drive in which it stores a copy of your local data. The data is updated every 10 seconds after the last change appeared. Synchronization status can be observed in the menu below the 'Sync data' button. The website only has access to the files it itself has created, none of your other Google Drive content. The following video explains how Google Drive is used to synchronize your data across devices.
