I was going to raise this question here. Then again, the only thing you might get is an identifier of the person that swiped left/right on you. You won't really be able to do much with that, though, unless you reverse-engineer the dating site's API and invoke it directly to access dating profiles. …which apps might be able to prevent by using device attestation / Google SafetyNet etc. (You can't easily extract the auth key required for the API.)
