Spyglass is a Quick Look Preview Extension plus a host app that signs into
Google (OAuth) to fetch rendered previews of Google Workspace files. It uses
the read-only drive.readonly scope, caches previews only on your
Mac, and has no server. Reports touching credential handling, OAuth token
storage, the Google client-secret configuration, or preview fetching are in
scope. Do not include real secrets, tokens, or personal
documents in a report — redact them.
