Search engines such as Google like tracking you, your search terms and IP addresses; they use this to build up profiles, store data, etc. To avoid this you can get a tool (Disconnect) at https://disconnect.me/search# which allows you to route your query through their proxy servers before they go to the popular search engines such as Google, Bing and Yahoo.
Alternatively, install DuckDuckGo as your search engine, as it does not track you.

I was always making notes on scraps of paper about tips and facts I'd read in books and magazines, seen on the Internet or on TV. So this is my paperless filing system for all those bits of information I want to access easily. (Please note: I live in the UK, so any financial or legal information relates only to the UK.)
