For example, when you give Groupon your information, you are also telling it to pass your information to all of the merchants and "business partners" that make up the Groupon network. And the kicker is that these companies may have completely different privacy policies.
"We encourage Groupon Merchants and business partners to adopt and post privacy policies. However, the use of your Personal Information by such parties is governed by the privacy policies of such parties and is not subject to our control," Groupon advises in its new policy.
