Terms of Use

Effective November 4, 2026

Ttobak (또박) is an app for learning Korean, made by Vectavox LLC. By using the app or this website you agree to these terms.

Your licence

Ttobak is licensed to you, not sold, under Apple's Standard Licensed Application End User License Agreement, together with these terms. If the two differ, Apple's agreement applies.

Learning content

Lessons, recordings, pronunciation guides and handwriting feedback are for learning. We work to make them accurate, but they can contain mistakes, and the voices are generated by software rather than recorded by people. Ttobak is not a substitute for a qualified teacher or official certification, and you shouldn't rely on it where a mistake would matter.

Using Ttobak

Please don't copy, resell, or redistribute the app's lessons, recordings or artwork, or try to reverse-engineer the app. You may share screenshots of your own progress.

Your data

Ttobak keeps your progress on your device. How we handle information is described in the Privacy Policy.

No warranty

Ttobak is provided “as is”, without warranties of any kind, to the extent the law allows. Vectavox LLC is not liable for indirect or consequential losses arising from using the app or website, to the extent the law allows. Nothing in these terms limits rights you have under consumer law that can't be limited.

Changes

We may update these terms as Ttobak changes. The date above shows the latest version. Continuing to use Ttobak after an update means you accept the new terms.
