  1. Thanks to GDPR and if you are in Europe, you can request to download a copy of your personal data from Duolingo via https:\/\/www.duolingo.com\/abc-privacy<\/a><\/li>\n\n\n\n
  2. The page tells you to send an email to privacy@duolingo.com<\/a><\/li>\n\n\n\n
  3. Then you receive an email which tells you to go to the page https:\/\/drive-thru.duolingo.com\/<\/a> and click on “Access Personal Data”
    \"Duolingo<\/li>\n\n\n\n
  4. You receive a confirmation email and few minutes later another email with a link to download a copy of your personal data<\/li>\n\n\n\n
  5. After uncompressing the file “duolingo.zip”, you can see quite a few files.<\/li>\n\n\n\n
  6. In particular, you can see in the file “metrics.csv<\/strong>” which shows that Duolingo tries to guess your approximate birthdate\/birthday:

    approximate_birthdate,country_code<\/code>
    YYYY-MM-DD HH:mm:ss.fff,XX<\/strong>
    \"Duolingo

    It is kind of funny to see Duolingo trying to guess my birthdate up to the milliseconds!

    Feel free to request your personal data too! \ud83d\ude0a
