Terms of Service

WaterStats only provides a convenient interface for add data to a Google Sheet, and then displaying that data.

The only Sheet that is viewable by the app is the sheet that is created by this app, but at that point you as the Google Account owner has full access to the data in the Sheet. WaterStats does not have permission to see any of your other data, and you are responsible for archiving the data at any point in time you feel is important.
