FAQ

Is duolingo.com safe?

Based on current analysis, duolingo.com leans generally safe with a 95/100 trust score. Key trust factors include 16.4-year domain history, public traffic rank, and business infrastructure; mixed review signals should still be checked.

What supports the trust score for duolingo.com?

Key factors include registrar information (Amazon Registrar, Inc.), hosting in US, a domain age of 16.4 years, and presence in public traffic rankings. Major malware and phishing engines did not report active blacklist detections at the time of review, but reputation-related warning signals were still present. The trust score blends security detections, domain and infrastructure signals, on-page behavior patterns, and public review history when available. The overall assessment remains mixed because third-party reputation sources do not point to a fully consistent trust profile.
