The lawmakers wrote to Google to express concern that users wouldn't be able to opt-out of the new data sharing system when using Chocolate Factory products.
"We believe that consumers should have the ability to opt out of data collection when they are not comfortable with a company's terms of service and that the ability to exercise that choice should be simple and straightforward," the letter said.
The policy looked to many commentators like Google would collect data on users whatever they surfed and whenever they used their phone and use it to target advertising and search results to them.
The US politicos said they were worried that some Google products and services are more hidden, so users might not necessarily know what data was being linked to them and that most products can't be used without logging in.
"What are the names of all of the Google products and services? For each product, are you able to use that product without logging in?" the letter demanded.
They also have bees in their bonnets about Android phones, which usually require a Google account of some description.
"Please explain exactly how a user of an Android phone will be affected by Google's new policy? Is there any ability for users to opt-out, other than not purchasing and using an Android phone?" the letter asked.
Congressman Ed Markey, one of the signatories to the letter, said on his website that he was particularly worried about how the new policy would affect young people.
"Googling is like breathing for millions of kids and teens - they can’t live without it," he said.
The Chocolate Factory took to its blog again following the letter to defend the new policy.
"So here’s the real story, you still have choice and control."
The posting then went on to answer some of the questions from the letter.
Google said that there was no need to log in to use a lot of its products, including search, maps and YouTube, and even when users were logged in, they could use privacy tools like 'incognito' to control their private data.
The search giant also said that it wasn't going to collect more data about its users, and it was just trying to "make things simpler". ®
