Trust & transparency

A concise overview of Nox's emergency alerts: what the basic red-flag check does, its published aggregate testing, its limits, and where to find the detailed accuracy report.

Safety at a glance

A basic, keyword-based check screens consumer messages for signs of a possible emergency before Nox answers. If it matches, Nox shows an emergency alert before its answer. It is a safety net, not a diagnosis or a guarantee.

Published aggregate testing

• Overall recall: 100.0% (154 of 154 should-fire cases produced a safety note)
• False-positive rate: 0.0% (0 of 53 benign cases triggered a note)
• Test set: 207 labeled cases · 107 rules across 75 categories

These results cover a maintained internal test set for Nox's emergency check. For the full methodology, scope, and detailed results, <a href="/accuracy">read the Accuracy &amp; testing report</a>.

Limits and accountability

Nox is an educational companion, not a medical device or replacement for a clinician. It does not claim to catch every emergency, and independent clinician review is not yet complete.
