I just noticed that the said "bully" has stated in his comments that you had integrated inspectlet.com. I checked it out and it looks like a screen recording service. If this is truly the case, then I think he may be correct as interpreting this as a violation of privacy.
I think the best course of action would be to do the following
1. Put up code on github as others have suggested, thereby reassuring existing users
2. Publicly state in a reply to the comment that you had indeed integrated the screen recording service to help you understand user behavior, so that you could make a better app.
3. Put a disclaimer on the details page for Google Analytics with a link to opt out.
