I don’t know how good their algorithm is nowadays, but generally Tinder will show you profiles they think you’d want to match with, but ideally not get in a lasting relationship with. They want you to keep using the platform, not find true love.

If you get swiped left enough, Tinder won’t really show you to most people. That part of their algorithm definitely works, it’s easy. I’m not sure if they’ve yet found a way to quantify risk of lasting relationship.
