Lots of reference to a user's private data - but what is private? Is my zipcode, gender, and birthdate private? Those three factors can be used to uniquely identify greater than 80% of the US population. Are the GPS locations I visit private? If so, why does information about them show up on lock screens?

Third parties get my voice recordings for "improving the voice recognition service" - what if my name is mentioned in the background of one of those recordings? What if I'm not a savvy user and add private data to those recordings?

You're also talking about what's in place today. If I give Google my data, that data is probably going to stay with Google as long as they are a business (and potentially after, if Google were ever liquidated and their assets sold off). What measures are in place to protect me then?

Yes, if data can be used to potentially locate somebody, like a combination of zipcode, birthdate and first name, it is considered PII (Personally identifiable information) and those strict policies would apply.

I'm responding to a comment that said trusting Google == trusting ALL Google employees, which is not true. Trusting Google with your data is believing that having some convenience (a mail service like Gmail, an intelligent assistant, etc.) is worth the risks you are talking about: Google drastically changing their policy, or being bankrupt and acquired by less scrupulous owners, etc.

Let's not just act like anybody at Google can look at your data and play with it, or a disgruntled employee will suddenly click a button and release all users' data on pastebin...
