How do I report a bug?

If you think that Duolingo is not behaving as expected, we would appreciate it if you'd let us know. We collect bug reports sent by users to detect emergencies and other issues. Please note that bug reports not always get a personalized follow-up reply, but they are monitored by our developers and help us improve the experience for all learners. You can report a bug directly to us by clicking here. Please consider making it as detailed as possible, including device, username, describing the action you were taking when the issue occurred and also taking a screenshot to include in the report.

If you have a purchase issue or an issue related to Super Duolingo, please select "Purchase Issue" from the dropdown on the form.

If you are locked out of your account because you are not receiving Duolingo emails, please read this first.
