here's a tip for u.
u can use incognito, u can use VPN, u can self destruct your pc.
but if authorities comes in, first this they gonna seize is your internet router cuz there stored all the logs.

so the tip to be safe is, make sure u use VPN client that does encryption b4 the data leaves ur device.
that way only the VPN provider can decrypt your browsing data.
but FYI, it's well known for VPN provider to secretly sells your browsing data to advertiser.
