Tor "non-exit relay" topic

Hello,

I hope I'm in the right section...

Google couldn't help me with that one so i hope i get an answer here. I just downloaded orbot and orweb.

In the settings of orbot i stumbled upon the message "enable your device to be a non-exit relay".

I'm not sure:
When i check it, am I a Exit-Relay? So the last one in the chain?
Or am I somewhere in the middle when i check it?


I don't want my phone to be the last chain part...

Cheers
Ghost
