Great app! Works better than the other duplication apps on chrome. The shift-click shortcut is genius and makes my life much easier. Wonderful extension!

Is GCal Duplicate & Duration Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

GCal Duplicate & Duration requires a few sensitive permissions. Exercise caution before installing.
