Yes. From the Admin menu on your desktop you can choose to download all your links as an "offline copy", to your local computer. They stay on that computer in encrypted form, so you must enter your Master Password to temporarily decrypt and view them. We recommend that you do this occasionally, and especially after entering new links, as a backup routine.
Please Note: You cannot add new links or modify existing data offline, with the objective of uploading the new file and replacing the former file inside Netsso. All editing in Netsso must be done online.
