Google is always careful about what it records. It will never activate itself without “hey Google” or “OK Google”.
Many people are worried that they have some spy that listens in on every conversation.
Google will never do anything unless you ask it. That’s the way it was programmed.
Not to steal your conversations.
Remember…You also have to take deliberate action. You have to press the microphone icon or say either “OK Google” or “Hey Google.”
