Most file comparison activity is local
DirectoryCompare Pro is not a cloud compare service. Local directory comparison, archive analysis, spreadsheet comparison,
image diff, patch workflows, exports, bookmarks, sessions, and many other features run locally on your device.
Licensing data may be machine-bound
The product uses machine-bound licensing for paid tiers. That means activation and entitlement logic can be tied to a machine identity
or similar device-specific information, depending on the licensing workflow in use.
Remote-source features are different from local-only use
If you compare GitHub repositories, web URLs, or FTP/SFTP sources, those workflows naturally involve communication with the relevant remote service.
That is separate from local folder comparison.
In plain English: local compare work stays local; remote compare work has to contact the remote system you asked the app to use.
