Support

September 20, 2026

If something is broken or a lesson is wrong, we want to know. We are a small team and we read everything that comes in.

Write to us

At soporte@unidior.com. We answer within 20 working days at the latest.

So we can help on the first try, tell us what you expected to happen and what happened instead, and add the app version (it is at the bottom of Settings) and your phone model.

I think a lesson is wrong

Send us the name of the lesson and the exercise, and the answer you gave. Right answers are never written by hand: the tooling works them out by running the code, so if something does not add up it is a bug of ours and we want to catch it.

I lost my uptime

If you had a hotfix saved, it covers the day you missed and the uptime carries on. If not, it starts from zero: nothing else is lost, not your XP and not your rank.

I changed phones and my progress is gone

For now progress lives on the phone, not in an account, so it does not travel between devices. The sign-in that will sync it is on the way.

The code will not run

Python and JavaScript ship inside the app and need no internet. If the editor keeps loading, close the app completely and open it again; if it still happens, write to us with your phone model.
