Cloud Duplicate Finer --- Removing Duplicates or Giving Away the Keys???

[DowntownChris]

I have a zillion duplicate photos in OneDrive, from multiple sources. I have seen a program, Cloud Duplicate Finder, which is a web app, and allegedly allows you to easily undupe files in OneDrive. Problem is, I need to give program access to my OneDrive files.

Is this an honorable program? Has anybody used it? I can find no online comments or reviews. I'd sure like some feedback on this program from somebody who has used it.

thanks
