@leocg No my post does not seems like that.
Yes it is very important for privacy, it sends a lot as I have written. My tablet model IS a personal information.
There's one app for Chrome only, for rooted devices.
If you want good examples, Firefox never sends you Android version, phone model, etc... and Via is only 0.5MB and allow to choose different user agent or modify it.
I notice that the 2d point of my post was deleted... OK, only moved, sorry.)
