Privacy
The Mail Merge add-on is designed to respect your privacy. All merging happens between your own Google Docs document and Google Sheets spreadsheet. No data is sent to me or any third parties. Feel free to check out the source code if you're worried (you can also go to Extensions -> Apps Script to see the compiled version running in your copy of the document).
Below is a breakdown of the permissions the Mail Merge add-on requests and the rationale for each.
| Permission | Reason |
|---|---|
| See, edit, create, and delete your Google Docs documents | Lets the add-on read the placeholders in your template and write the merged result into a new document. Google only grants the edit permission alongside see, create, and delete. This add-on will only read and write documents you interact with through the sidebar; it will never open or modify unrelated documents. |
| See, edit, create, and delete your Google Sheets spreadsheets | Lets the add-on read the rows and columns from the spreadsheet you choose so it can fill in your template. This add-on will only read the spreadsheet you select in the sidebar. |
| See, edit, create, and delete all your Google Drive files | Lets you browse your Drive to pick a spreadsheet as the data source, and lets the add-on save the merged document alongside your template. Google requests this broader Drive permission because the file picker needs to search across your whole Drive; the add-on itself only touches the template and spreadsheet you choose. |
