No Microsoft access
Call State never asks for a Microsoft login and never uses Microsoft sign-in keys. It is an independent tool and never signs in to Teams for you.
Guide · Your data
What leaves
your computer.
Not a Microsoft product, not inside your meeting. Call State reads button states in Teams and sends only small status data — never your content.
How Call State handles your data
Not in the meeting
Call State does not join your call. Other people do not see it in the participant list, and it cannot hear or record anything.
Buttons, not content
Each button has a fixed name that Teams gives it, like “Unmute mic”. Call State reads that name and whether the button is on or off — never anything of yours: no text, messages, documents or pictures.

Never leaves your computer
- Meeting audio and video
- Your screen and anything you share
- Chat messages, files and attachments
- Transcripts and recordings
- Your calendar and your contacts
- Your Microsoft account and any Microsoft sign-in keys
Leaves your computer (small status data only)
- Whether you are in a meeting
- Muted, camera on, hand raised
- Sharing active, chat pane open, participant list open, recording indicator active
- When the current call started and when the status was last read
- Whether a control such as the mute button can be used right now
- A random device id (new on every start) and the name of your computer
Separately, your account stores your email, a value from your password and billing details — card details go only to Stripe. If you turn on MQTT, the desktop app also sends the same status data to the MQTT broker you choose, usually one in your own network. More questions about your data
