No Cross-Site Advertising Trackers

IllumiU does not use marketing cookies, tracking pixels, or third-party behavioral advertising scripts. All browser storage is strictly functional, operational, or diagnostic to ensure your admissions workspace functions smoothly.

1. How We Use Browser Storage

Modern web applications store small pieces of state in your web browser via HTTP cookies, Local Storage, and Session Storage. IllumiU utilizes these technologies exclusively to:

  • Maintain Secure Authentication: Preserving your cryptographically signed login session across page refreshes.
  • Remember Interface Preferences: Remembering whether your navigation sidebar is expanded or collapsed.
  • Enable Offline Resilience & Sandboxes: Supporting interactive demo exploration and guest scratchpads before signing up.
  • Client Diagnostics: Measuring client planning calculation latency to detect performance regressions.
