Does this work with SSO links?

Yes. We verify that the deep links in the calendar event actually redirect to your specific SSO login page, ensuring mobile users can launch training effortlessly.

Why do my recurring events look broken?

Cornerstone exports recurring events in a way that often breaks Outlook. Lokr sanitizes the RRULE property to ensure every recurrence appears correctly.

Does it support virtual ILT?

Yes. We parse the Location field to extract Zoom/Teams links and place them in a clickable 'Join Meeting' button within the event.

Is it secure for government use?

Yes. We offer FedRAMP-friendly deployment options and do not store any PII.

Q: Can I filter out completed training?
