Data Privacy for Google Charts

Question

We're looking at adding charts to our webapp. I recommended using a 3rd-party service such as Google Charts; this idea was rejected over fears about client data being passed to Google.

Google's Privacy Policy (which appears to apply to Charts) seems to preclude the abuse of our data, since it states that they require opt-in to share it with anyone. Still, I'm not sure of this.

Is there a legitimate concern here with respect to privacy/security of the data we send to Google?

Answer 1

Is your web app to be used only by your company or also by your company's clients? If there are clients involved, then that would be a strong reason not to use Google Charts. After all, you can't take the decision to send your client's their data to Google, no matter what Google's Privacy Policy states.
