Answer
If you download the app again through the App Store or Google Play, your account will still be there when you log in. Similarly, although most apps offer the option to delete your profile in Settings — which you should do — there’s still one more step you should take to be sure it’s gone for good.

If you want to cancel your account, be sure to note that on the request form. This procedure might take up to 30 days and will need our staff to verify your identity in order for us to accept that you are the account owner and have a right to terminate it.
However, you cannot write any more messages once your match’s profile photo has been deleted. If these indications aren’t convincing enough for you, you may examine the bottom of the conversation window to see if it says “We regret to inform you that his user has departed.”
Yes, and the long answer is “no.” You used to be able to determine when someone you’d matched with last used the app. Unless they disclose it by sending you a message, there’s no way to tell how long it’s been since they were on Bumble if you look through your matches.
Bumble does not include a user search option. Because it goes against the core purpose of the browse function, it is unlikely to have one. Nobody would bother checking out their profile stacks or swiping if you could look for people. So the appeal of being able to check if your partner is on Bumble has vanished.
