What we access
Calendar Call Alert requests the calendar.readonly OAuth scope. This allows the extension to read events from your primary Google Calendar — specifically, each event's title, start time, end time, conference data, location, description, and Google Calendar event link. The extension scans those fields locally to find Google Meet, Zoom, or Microsoft Teams invite URLs. No other data is read.
The extension does not access Gmail, Google Drive, Google Contacts, secondary calendars, or any other Google service.
What we do with it
We use the calendar data exclusively to compute when to schedule a local browser alarm. The alarm fires 60 seconds before a video meeting starts (Google Meet, Zoom, or Microsoft Teams). All computation occurs inside your browser using Chrome's built-in alarms API. The meeting title and platform are displayed in the Chrome notification and, while the ring is playing, in the extension's floating alert popup window. Join opens the invite URL from your calendar event in a new browser tab — the extension does not connect to Zoom, Microsoft, or Meet servers directly.
No calendar data is sent to our servers unless you enable SMS alerts. Then the extension sends only the meeting title, start time, and join URL so we can text you. Calendar sync itself still talks only to Google's Calendar API.
What we do not do with it
- We do not send your full calendar off the device.
- We do not use calendar data for advertising.
- We do not allow humans to read your calendar data.
- We do not use calendar data to train AI or machine-learning models.
- We do not share calendar data except the SMS notify payload (title, time, join URL) if you opt in.
Compliance statement
Calendar Call Alert's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. We access only the data necessary to provide the meeting-alert feature. Calendar sync stays on your device. If you subscribe to SMS, we send only the meeting title, start time, and join URL to deliver that text.
