"Online filth" is in your website header, so your kinda focusing on them. I looked at the reviews and your most recent one continues to reinforce something about "filth" https://play.google.com/store/apps/details?id=com.camhart.ne...
As far as not being used "on" someone. Again you have reviews from Spouses and Parents which would imply they are being used "on" someone. Something I noticed the other apps focus on is individual accountability. I see almost no reference to spouses or parents there. Just having some you trust to be accountable too.
Your first line on google play says "Truple protects your loved ones against porn & other online filth. It holds your loved ones accountable in a way that's near impossible to bypass by capturing and sharing screenshots." How exactly is that not it being "used on anyone"?
Your marketing around this tells a story of surveillance trying to pass it off as some "good" where accountability is a secondary issue. While here you are focused on accountability.
And personally I have to wonder if Apple takes this into account when approving apps (which I assume they do)
