After some effort to find decent Android TV Web Browser that can work without hacks and support basic 'mouse' navigation using TV remote, I wrote one myself.

Doesn't spy at all and has no idea what you are looking at. All the traffic goes directly to Android TV device with no intermediary servers. Under active development so with feedback it can only get better.

Very useful, very decent performance, will always remain free, will never spy on you.
