A Chrome extension that turns your Canvas courses into one calendar, with optional Google Calendar sync. It runs in your browser. There is no Companion account and no Companion server for your coursework.
Sync is optional. If you click Sync to Google Cal in the extension, Google will ask you to allow Canvas Companion to add and update events on your calendar. Canvas login cookies are never sent to Google.
Install it from the Chrome Web Store when it is listed, then connect Canvas and sign in with Google.
