A Tinder user will not be notified or otherwise alerted if you swipe left on them, meaning that you don’t need to feel too worried about hurting someone’s feelings. Obviously, if someone swipes right on you and you aren’t a match, they’ll know that you haven’t swiped right, but this could be for a variety of reasons: Either you haven’t seen their profile yet, or you are not a frequent user of the app, or you have indeed swiped left for a variety of potential reasons.
How Do You Know If Someone Swiped Right on You?
The only way that you can tell for sure if someone has swiped right on you is to swipe right on them, too. However, we’ll let you in on a secret: People who’ve already swiped right on you are likely to show up near the beginning of your queue, so it could be worth paying careful attention to them as you are likelier to be a match.
How Long Does It Take to Get a Match?
There is no set answer for how long it takes to get matches on Tinder. In fact, there’s no rock solid guarantee you will get matches at all. However, if you have a strong profile and sound swiping strategy, you could theoretically be getting matches as soon as you start swiping, though for most people, it will take from a few hours to a few days to start seeing results.
How Long Do Matches Stay?
Tinder matches and any associated messages will remain until either you or your match deletes their Tinder account. Tinder users also have the option of “unmatching” users, which means that even if you become a match, either one of you can change your mind and unmatch the other. Otherwise, Tinder matches hang around until you decide to finally strike up a conversation, unlike other apps such as Bumble which instill a time limitation.
Why Don’t You Have Matches Yet?
If you have been using Tinder for a while and still don’t have any matches, you’ll need to reevaluate your profile. Check out the profile section above, and perhaps even consult a friend or two who could help make your profile more attractive and appealing.
Can You Find People You Know on Tinder?
It’s perfectly possible to see someone you know appearing on your queue on Tinder. 
If one of your friends or coworkers lives in your area and happens to be on Tinder with the same age and gender parameters as you, they may well appear in your queue, and vice versa. That’s just how social media works, folks!
Some people find the prospect of being seen on Tinder slightly embarrassing, but there’s really no reason to. It’s a hugely popular dating app and people use it for a variety of different reasons, plus your friend or coworker is also a user! If you see someone you know, you could swipe right and have a laugh about it if you match, or else just swipe left and forget about it.
Should I Swipe Right on Everyone to Get More Matches?
Constantly right-swiping to game the system is a bad idea. Swiping right indiscriminately just means you’ll match with people you may not be interested in, which is annoying for them and you, wasting their time and clogging up your messages. Swipe right only on those you genuinely hope to match with so that when you see that coveted, “Congratulations! It’s a match!” alert, it actually means something. Not only that, but new iterations of the app penalize indiscriminate swipers, so you’re better off being choosy.
