The Hungarian competition regulatory authority has launched an investigation into neighboring countries, alleging that they are putting psychological pressure on consumers.

The Hungarian Competition Authority announced on September 17 that it has initiated a competition monitoring procedure against Duolingo, accusing them of potentially misleading users about the effectiveness of their language learning program. The company is believed to have exerted psychological pressure on consumers by sending unnecessary and frequent direct marketing information to encourage them to use their service and switch to the paid version, without properly providing information about the terms of use of their service, especially the limitations of free use.
