We use Pixevity and love it.
However we don’t necessarily use it for the same reason. We have a list of our no-photo kids with their photos, name and class and know them pretty well. We only have a yes or no option for media permissions too, which saves us having to worry about the specifics. Our class teachers are also very aware and helpful.
Happy to chat or show you our pixevity if you like.
