Terms of use

The short version: use Parnasso to learn, be kind with challenge links, and know that it is a beta.

The service

Parnasso is provided as it is, during a beta. Rule checking follows the common textbook rules of species counterpoint after Fux; teachers and textbooks differ on details, so treat its feedback as guidance, not a final grade.

Your work

The lines you write are yours. When you share a challenge link or image, you allow anyone with the link to see that exercise.

Accounts

Keep access to your email account safe: it is how you sign in. We may suspend accounts that abuse the service, for example by flooding challenge links or lists.

Paid plans

There are no paid plans yet. When there are, their price and terms will be shown before you pay.

Changes

We may update these terms as the service grows. The date below shows the latest version.
