Privacy experts say that with any smart device, consumers need to be aware of what information is being collected and proactively manage that data. Facebook on Wednesday shared more details about the privacy and security safeguards the tech firm put in place. Still, it will be up to consumers to decide if that's enough to trust the social network. 

What information does Portal collect? Facebook points out that the tech firm won't be listening to, viewing or keeping the contents of Portal's video calls, but that doesn't mean the company isn't tracking any information about you. The company said it processes data such as the frequency and length of your calls, but not what you're saying in them.
