The answer to that, thankfully, is no: you are the only one who can tell you’re using Tinder Gold by direct means. However, that doesn’t rule out someone figuring out that you have Tinder Gold (or at least Tinder Plus) by indirect means.
Also to know is, how long does Tinder boost last?
Tinder Boost gives you exactly that: a way to be one of the top profiles in your area for 30 minutes. Increase your chances for a match—you can get up to 10x more profile views while boosting.
Then, what does 24 hours left mean on Tinder?
As a Tinder Gold or Platinum member, your daily Picks will refresh every 24 hours. If you purchased additional Picks, you have 24 hours to view or swipe them before they disappear.
