Terms of use

Updated August 7, 2026.

By using TessiTune you agree to the terms below. They describe what we offer, what we expect from you, and the limits of our responsibility.

TessiTune is a musical training application used in the browser. Exercises and tools work without an account; the account keeps your progress. The app is under continuous development: exercises are added, reshaped, and rarely removed.

You are responsible for the information you register and for keeping access to your account secure. The account is personal and must not be shared.

Use TessiTune for musical study. Do not abuse the infrastructure, attempt to access other accounts’ data, or redistribute the service’s content without permission.

TessiTune is provided as is. We work to keep the service stable, but we do not guarantee uninterrupted availability or specific musical results.

We may update these terms. Material changes will be noted on the site or by email. Continued use after an update means you accept the new version.
