A FEW GOOD QUESTIONS
Before you add it.
Is this an official GCU product?+
No. Halo Global Calendar is an independent tool made by a student. It is not affiliated with or endorsed by Grand Canyon University.
Where is my information stored?+
In your browser’s extension storage, on your own computer. There’s no account, and your classes, grades and announcements are never sent to the developer or anyone else. Read the privacy policy.
Does it change anything in Halo?+
It only reads your own Halo pages. The one exception is Acknowledge: when you click it on an announcement, the extension presses Halo’s own Acknowledge button for that post. It never submits work, posts anything or changes your settings.
Can I go back to the normal Halo?+
Yes. In the calendar’s options menu, Revert to Default shows Halo exactly as it was. Click the H+ in Halo’s top bar to bring Global Calendar back. Settings can also turn off just the theme or the home page.
Can I use it on my phone?+
No. It works in desktop browsers: Chrome and Edge now, and Firefox and Safari on the Mac soon. Phones and tablets can’t install these extensions, but this website works on any device.
Is it free? Why is there a small ad?+
It’s free. A small sign marked “Ad” sits in the empty middle of Halo’s top bar. It’s a plain link with no ad network or tracking, it never covers Halo’s buttons, and its × hides it for good.
Does it replace Halo?+
No. It helps you see and plan your work across classes. Keep using Halo for submissions, course materials and official deadlines and grades.
