The issue arises if you have the TV's voice recognition feature turned on to allow you to control the TV with voice commands.
Samsung itself may also capture voice commands, including the versions converted to text, the company said.
Data collection can be disabled
Samsung noted that users can disable voice recognition data collection in the settings menu.
"However, this may prevent you from using all of the voice recognition features," the document said.
The updated policy was flagged last week by the online news website The Daily Beast.
In a statement to The Daily Beast and several other media outlets, the company noted that it takes consumer privacy seriously and uses "industry-standard security safeguards and practices, including data encryption, to secure consumers' personal information and prevent unauthorized collection or use."
Samsungs are not the only SmartTVs that have raised privacy concerns since they hit the market.
In 2013, LG Electronics Inc. confirmed that some of its smart TVs were sending information on home viewing habits back to the company without consent. It said it would fix the problem.
