Is duolingo.com a scam? Here's what we found.
The site boasts a valid SSL certificate using TLS 1.2 and is clean according to Google Web Risk, indicating a secure browsing experience. The only minor point is Amazon as a certificate issuer, which is entirely fine but not the most premium like Digicert, for instance.
With a domain age of over 16 years, the site possesses a strong and established online identity. The use of Amazon Registrar, Inc. is standard for large corporations, offering reliability.
As one of the most visited websites globally (Tranco Rank #476) and being clean on DNS blacklists, Duolingo has a very strong reputation. The lack of a Trustpilot profile is not a negative given its stature.
While legal pages are present, the absence of obvious contact information and social media links on the homepage makes direct communication and engagement less straightforward for users.
The presence of both a privacy policy and terms of service demonstrates good compliance with legal and ethical data handling standards, essential for any service handling user data.
The site benefits from a robust DNS setup, DMARC for email authentication, and fast page load times. The minor sitemap misconfiguration is a small flaw in an otherwise excellent technical foundation.
