Qmee PayPal Link

So I've always been super cautious about linking PayPal to any beer money app because we'll, it's PayPal. I don't link debit cards to things or etc either (I did but I don't like the idea, it didn't sit well after a while)

I didn't do it with Zynn (I know that was a new player) but should I be concerned with qmee?

I'm sure most of you have done it, so I just want to make sure I'm not being over trusting just because they've been around a while.
