About this extension
Stop forgetting Gradescope deadlines. Sync them to Google Calendar automatically.

Built by a student who kept missing deadlines across 6 different courses.

HOW IT WORKS
  1. Visit Gradescope once - the extension learns your courses
  2. Connect Google Calendar (one-time, 30 seconds)
  3. Done. Assignments sync automatically, even when you're not on Gradescope.

No manual work. No forgotten deadlines. Just check your calendar.

Developer comments
KNOWN COMPATIBILITY ISSUE:
Google OAuth may fail during initial setup if Privacy Badger, ClearURL, or similar privacy extensions are active. You'll see an "Unknown Error" at the final OAuth step.
WORKAROUND:
  1. Temporarily disable privacy extensions
  2. Complete Google Calendar connection (takes 30 seconds)
  3. Re-enable privacy extensions

Once connected, all privacy extensions work normally with Gradescope to Cal.
This is a Google OAuth redirect issue, not a bug in this extension. I'm investigating workarounds for future versions.
