Terms of Use

The basics

These terms are an agreement between you and Jude Hilgendorf, who operates Keystair. Using Keystair means you’re agreeing to these terms, so if you disagree, please don’t use it.

Who can use Keystair

You must be 13 or older to use Keystair. If you’re younger than 18, have a parent or guardian go over these terms with you.

Your account

Keep your password secure, and let us know if you suspect anyone else has gotten into your account, since you’re responsible for what happens in it. Each account is intended for just one person. Avoid usernames that pretend to be someone else or are offensive; we might change or remove such names.

Using Keystair

Keystair is meant for your own learning. Please don’t:

• try to tamper with the site, overload it, or find ways around its security,
• access other people’s accounts,
• copy lessons in large quantities or publish them elsewhere,
• use bots to create new accounts or send messages, or
• use Keystair for any illegal activities.

The music and the lessons

The music in Keystair is from the public domain, but the lessons, arrangements, words, layout, and code belong to us. Feel free to use them to learn, though not to redistribute or sell them.

What you send us

Messages you send us belong to you. We get to read and save them to help reply to you and improve Keystair. If you share ideas, we might use them but won’t owe you anything in return.

Free, and as it is

Keystair is free. If we add paid features in the future, we’ll make that clear first, and you won’t be charged for anything without your consent.

We try to keep Keystair running smoothly and free of errors, but it’s provided “as is,” without warranties of any kind. We can’t promise it will always be up or never make a mistake, and it isn’t a substitute for a piano teacher.

Practice safely

Take breaks and stop if your hands, wrists or arms feel pain. Make sure the volume isn’t too loud, particularly when using headphones.

Limits on liability

As far as the law allows, we aren’t liable for any indirect or consequential damages or for lost data, and our total liability to you for anything to do with Keystair is capped at $50. Some places might not permit limits like these, so not all of them may apply to you.

Ending

You can remove your account at any time in Settings, Account. We might suspend or close an account if it violates these terms, and we could also alter Keystair or stop operating it. If we decide to shut it down, we’ll give notice beforehand when we can, so you have a chance to download your data.

Changes to these terms

When these terms are updated, the date at the top changes to match. For major revisions, we’ll tell you in the app before they take effect; by continuing to use Keystair afterward, you agree to the updated terms.

The law

These terms are governed by the laws of Michigan, United States, and any disputes are settled in Michigan’s courts. Nothing here takes away protections you have under local laws that can’t be waived.
