When users use ValueInvesting.io's Excel add-in, we will access your spreadsheets' information to obtain your unique API Key we assigned to you when you registered an account with us on our website. That key is a part of the API call to our endpoint. ValueInvesting.io will also be allowed to edit users' spreadsheets in order to populate the spreadsheets with financial data. We do not use any other data and we do not store or share any Excel user data from our Excel add-in.
