Encrypt all the things!

I think I've already given most of my info away. Is there any point, or ability to repair the damage?

You can't get back or undo that which has already been done.

But you can stop giving more info, and stop fleshing your profile out further. You can basically drop off their web from their perspective, and yet continue to do everything you usually do.

Also there are some products/services I really like and find useful such as google; chrome, the various chrome ad-ons, google docs, etc. I assume google is the main purveyor of info so is there anything to be done to roll that back?

I use those too. I silo them into a little box so that only see that use and nothing else.

How to do this? Split your online life into 2 web browsers.

I use Firefox for 90% of web use, and Chrome for 10% email/docs/maps use.

Firefox is permanently in Private Browsing mode, and I fire up Chrome in "Incognito" mode. Neither remembers a single cookie from one browsing session to the next.

Then I use a VPN to encrypt all traffic, and with Firefox I also use Tor.

The only thing I have to think about, is if I have a link in any email I copy it manually to the Firefox browser.

Hmm, what else? I use DuckDuckGo for search, and the Dolphin browser on my phone.

Basically, I still use Google, but I silo them, deny them a permanent cookie, encrypt all traffic to them, and prevent them seeing everything else I do.

I shall now don my tinfoil hat.
