Common questions

The calendar is empty, or the sync stopped.

Make sure you’re signed in to Halo in the same browser, then click Sync all classes again. If Halo was slow or changed its layout, the extension keeps your previous calendar and says what went wrong.

An assignment is missing or shows the wrong date.

Sync again first. If it’s still wrong, open Settings, click Download diagnostic log, and email it to support@keenwha.com with the class and assignment. The log has names, titles and numbers removed.

I have an accommodation. Which due date is shown?

Your own accommodated due date, wherever Halo shows one.

Where is my information kept?

Only in your browser, on your device. Nothing is sent to us. See the privacy policy.

How do I remove it?

In Chrome, remove it from the Extensions page. In Safari, delete the Halo Global Calendar app. Either way, everything it saved is deleted.
