When you use Hunter's Google Sheets Add-on (Hunter for Sheets), Google asks for your permission at two levels: once for your Google account, and once per spreadsheet.
Signing in with Google
When you sign in, Google shares two things with the add-on:
"See your primary Google Account email address" — this links the add-on to your Hunter account and keeps you signed in.
"See your personal info, including any personal info you've made publicly available" — in practice, your name and profile picture, as shown on the sign-in screen.
Allowing the add-on to run in a spreadsheet
The first time you use the add-on in a spreadsheet, it asks for permission to run in that document. This lets it read the data you select — for example, first names, last names, and domains — and write the results, such as email addresses and verification statuses, back into the sheet.
👉 Access is granted per spreadsheet — the add-on can only work in documents where you've given it permission, and it doesn't have access to the rest of your Google Drive.
To get started with the add-on itself, see the Google Sheets Add-on guide. If anything isn't working as expected, contact our support team, and we'll help you out.
