Anytime you're using the internet for personal reasons, it's smart to use Anonymizer.

At work - Anonymizer prevents co-workers or competitors from seeing what web sites you visit.

Visiting medical, legal, employment or political web sites - Don't let insurance companies, your boss or other third parties have this personal data.

With your children - Protect a vulnerable audience from dangerous individuals and unscrupulous marketers.

Entertainment - Because your interests are your business.

Online Shopping - Would you let a team of marketers follow you around a department store to "get to know you better?" Shopping without the Anonymizer amounts to the same thing.
