May I see a photo of the person I will go on a date with?
No! If you could do that, Pairfactory would not be that much better than a classic dating site. We think that people should, first of all, have compatible personalities and not just good photos. After the date, you will fill a feedback form where you could also specify what of that person's it was that you disliked.

Could you tell me what the algorithm for setting up dates is?
No!
