The purpose [behind in the paper works] of gathering information is for statistics purposes on how to improve services.Why does an ISP need my browsing data? Sounds greedy.
This will not particularly help. All traffic you have will pass from their servers. So if you don't use a vpn they will still see the locations you are connecting and when not on ssl even the data you are passing through if they wanted.It's much ado about nothing, just make sure you make it hard for them,
one step is replacing your DNS servers from the default your ISP assigns,
"if they let you change it" mine does so I use AdGuards DNS servers.
I am not saying this will stop all or that this is all you need to do, but
it is a big step in the right direction
Step 1> Change your DNS to Adguard or another secure 3rd party.
Step 2> Use a homepage and search engine that will not track you
or collect info, I use the Duck.
Other steps include cleaning your browser regularly, set it to clean at closing,
I do this and have Ccleaner clean it too at closing, just to make sure.
First thing comes to my mind is that they will sell all the data about you to advertisers.Why does an ISP need my browsing data? Sounds greedy.
It is not said that using a VPN is the best things. A VPN directs all your Internet traffic through the servers of a company. Your navigation then, seems to come from that company and your provider cannot know which sites you visit, because the connection from your device to the company that offers the VPN is encrypted. But this means that all your browsing activity is passing through the provider of the VPN, which could sell it or read it, for example, if you visit questionable sites. Using a free VPN or provided by strangers providers, could reduce your privacy navigation.I'm not sure, would a VPN exclude your ISP to track the browsing history? I think yes.
Of course, it is mandatory to change DNS too: using the ISP defaults will let them track your destination before you reach it.
