Google Workspace
- It can read
- Gmail, Google Calendar, Google Drive and your contacts — the messages, files and appointments you authorise, and nothing outside them.
- It can send, once you allow it
- A reply or a new message from your Gmail address, and an event in your calendar — each one shown to you first, and sent only when you say yes.
You choose at the moment of connecting whether it may read mail at all, and sending stays off until you turn it on separately.
