This is my security problem.
So, I'm connecting to the internet through a WLAN network, shared by another person, we both are admins over the network and know the password, but he is a computer guru and is into hacking, and I'm a computer illiterate.
The thing is, he gave remarks about "sniffing" my data (Aka Web browsing for the most part) and I think he is serious, I'm trying to protect my privacy here, I asked in a lot of places but the answer always was "get a VPN" and I can't afford that. :(
I want to protect my data but he is on the same network (and an admin nonetheless).
What should I do?
