Yes, it's true even for android. From: https://www.android.com/pay/

Your card info stays safe When you use your phone to pay in stores, Android Pay doesn’t send your actual credit or debit card number with your payment. Instead we use a virtual account number to represent your account info – so your card details stay safe and secure.

Unfortunately it doesn't work for me, it's stuck at 60%.

Edit: I'm stupid, I disabled WebRTC on FF, works fine with Chromium.

So true. And even if you're careful with your own data...some other person might not and upload and tag photos with your name.
