How this was checkedPolicy history
Screen recordings submitted to Abouit by users who stated they show cancelling or deleting their own account. Abouit did not record them and cannot verify who made them. Screens are counted by our published method. Submitted recordings are reported evidence: never a receipt, never part of a grade.

What we checked in each of the six areas, and what we found there. Not a score: an empty area means not tested yet; "their words" means we quote their documents below but have not tested it.

Sentences copied word for word from the latest annual report of the company behind Duolingo. Companies must tell investors what their business depends on.
