Contact
One address for everything — support, privacy questions, account deletion, bug reports, press.
Email us
We read every message and usually reply within two working days. Write in English, 한국어, Deutsch or 日本語 — whichever is easiest for you.
From inside the app
Nanna has a shortcut that fills in the details we usually need: open the Today tab → tap the gear icon → scroll to Data → Contact us. It opens your mail app with the app version, device model, operating system and language already filled in.
If you write from your own mail app instead, those four details help us a lot.
