Confidence
The domain duolingo.com matches the official primary site of Duolingo, Inc., a Delaware public company with NASDAQ listing and roughly 16 years of registration history. Technical checks show zero malicious detections, valid SSL, and a clean hosting IP with no abuse reports. Evidence confirms the site is not a clone and includes proper business registration details. User complaints exist around billing practices and subscription auto-renewals on platforms like Reddit and independent review aggregator, but these relate to service experience rather than site fraud or malware. No scam-family patterns or impersonation indicators were triggered for the domain itself.

Still, stay alert

No major threat indicators — but a clean scan does not guarantee every page is safe, and phishing emails routinely spoof real domains.

  • Double-check the exact URL in your address bar

    Confirm you are actually on duolingo.com and not a lookalike like d-uolingo.com.com or an IDN homoglyph.

  • Use a password manager

    Password managers only auto-fill on the exact domain they were saved for — they refuse to fill lookalike domains, which is the single best phishing defence.

  • Discuss this site on the forum

    If you have first-hand experience with this site — good or bad — share it with the MalwareTips community.
