I think it's similar to [Security Through Obscurity](https://en.wikipedia.org/wiki/Security_through_obscurity https://en.wikipedia.org/wiki/Security_through_obscurity), since Google may not be interested in one single person. But still, it only means Google doesn't want to, It doesn't mean they are not able to. Plus, using Google Sheets as backend means you have to choose "publish to the web". While the data was set to public, you've dropped the [expectation of privacy](https://en.wikipedia.org/wiki/Expectation_of_privacy https://en.wikipedia.org/wiki/Expectation_of_privacy). And I'm sure Google is still going to analyze your usage of their product no matter what.
