Features & Capabilities

USC Schedule Helper improves the USC class search and Web Registration experience. It adds professor ratings to class results, highlights schedule conflicts, shows unit totals, provides a calendar export shortcut, and lets students request class availability notifications.

Email notifications are free. Optional SMS notifications cost $1 per section per semester.

The extension runs only on classes.usc.edu and webreg.usc.edu. Notification requests send the email address, optional phone number, and selected class details that the user submits to usc.jonlu.ca. See the privacy policy at https://usc.jonlu.ca/privacy.

Is USC Schedule Helper Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

USC Schedule Helper requires very minimum permissions.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

USC Schedule Helper is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
