The phrasing is misleading. The add-on cannot run without you present. In order to fetch the document without any formatting problems we needed to use ScriptService which causes this permissions prompt.

See related: https://code.google.com/p/google-apps-script-issues/issues/d...

I see it requests both these permissions: - View and manage the files and documents in your Google Drive - View and manage documents that this application has been installed in

The second one seems reasonable. But the first has this description: "Upload, download, update, and delete files in your Google Drive Create, access, update, and delete native Google documents in your Google Drive Manage files and documents in your Google Drive (e.g., search, organize, and modify permissions and other metadata, such as title)"

That sounds like full access to every document in my google drive. No thank you!

Rest assured! We don't automatically charge you - at 3 documents you're notified that you've reached your document limit for the month. You'd have to directly go into our dashboard and add your credit card and sign up for the premium plan (with 30-day free trial) for pricing to take effect.
