Google’s new unified privacy policy takes effect on March 1st, allowing Google to share users’ data among all of its products. This means that your entire Google Web History – everything you’ve searched for on Google, and every site you’ve visited while signed in to a Google account – will be pooled together.

Understand that if your Google account is compromised, the sheer amount of data your account holds could lead to insanely damaging identity theft or fraud – so you’d best clear up at least some of the data attached to your name.

The Electronic Frontier Foundation has posted instructions for removing your web history, which also stops it from being collected in the future. Short of deleting your Google account, this is the only way to keep your super-secret data from being merged with everything Google knows about you – from Google+ to YouTube.

Think of it as spring cleaning.
