They have a creepy function where they show you who you've crossed paths with and will note how many times you've been in their proximity. I'm fine with then using location to show women in my city. Not comfortable with my info being shown to strangers that we've crossed paths several times. I had one woman show that we crossed paths multiple times. I didn't sign up for that. This should be an opt in feature. I'm a guy and I'm freaked out. Women must feel like their being stalked.
