If one of your Matches has disappeared, it’s likely that they have deleted their Tinder account or unmatched with you. If this is the case and they return, you will see this person back in your profile gallery.
How to Check if Someone is Still Active on Tinder
… I would say that I can provide a good answer. If a profile is displayed, the person has logged into Tinder within the past 2 weeks. If there is a green dot on a profile, it means the person has been active within the last 24 hours.
Why Can’t I See a Profile on Tinder Anymore?
The best course of action is to check your Internet connection, then delete and reinstall the app. This will download the latest version of Tinder and refresh the experience in the app, which should solve the issue!
Automatic Deletion of Tinder Account
If you choose to Delete Account, after 90 days, Tinder will change your account from "disabled" to "deleted." On the next screen, choosing to suspend your account or delete it permanently will simply deactivate your account. If you log back in during this period, the deletion will be canceled. To delete your account, tap the last icon on the bottom bar, go to SETTINGS in your profile, scroll up to show the bottom of the page, and tap DELETE MY ACCOUNT. Provide the reason for leaving, tap DELETE MY ACCOUNT again, and delete the Tinder app from all your devices. Do not log back in for 90 days.
