Data is money, but there is a trade off in security, when using online services. However there are a number of tools/services for those who want that extra bit of secrecy.
DuckDuckGo.com – Search Engine (www.duckduckgo.com)
DuckDuckgo is great, if you want to search (I nearly typed google) for something and you didn’t google, or perhaps the company or site you are searching for to know that you are visiting their site. Even as an alternative to Google search it is well worth using.
SpiderOak is an alternative to Box, Dropbox, iCloud, Copy, OneDrive, and Google Drive. Just like the other services it is a backup, file sharing and messaging platform, with additional security that the other platforms.
Tor Project Browser (www.torproject.org)
While surfing the web, you do leave a trail, perhaps a bit obsessive but the Tor Browser is a way to hide your surfing. Other browsers have their incognito, or browse in secret options but Tor is that extra level of secrecy.
Personally the benefits in using Google and Microsoft software online outweigh the price you pay in data secrecy. It is beneficial, for the search engine to have access to data about you, making the search results more relevant.
