@alice No freemium stuff at all. Either free with the possibility of tipping or paid for everyone.
Disable geopositioning after matching, ideally don't rely on it at all. When I was online dating if I opened a profile after matching, their position would update. This can be used for stalking, at best that's creepy and at worst it can cause real safety concerns.
Possibility to enter words or hashtags in a filter bar to prioritize or exclude profiles with them in their description. To make it easier to find profiles with similar interests or values.
No AI text generation, image filter or profile suggestion whatsoever. It goes without saying.
