Terms of use

Clefsight is a website for learning to read music at a keyboard. Using it, with or without an account, means agreeing to these terms.

Who runs it

Clefsight is run by Buretto Technologies Inc., a British Columbia company, 422 Richards St, Suite 170, Vancouver, BC V6B 2Z4, Canada.

Who it's for

Clefsight is made for adults and is not directed to children. To make an account you must be 16 or older.

Your account

An account is optional and playing never needs one. Keep access to your email address to yourself, since a code sent there signs you in. You can delete your account at any time in Settings. We may close an account used to break these terms or the law.

Scores you bring

Bring only scores you have the right to use. A score you bring stays private to you: it is never shown to anyone else or added to the library. Signed in, a copy is kept on your account so it reaches your other computers. If we receive a valid notice that a score kept on an account infringes someone's copyright, we may remove it.

The library

The library's compositions are in the public domain in Canada and the United States, or traditional tunes, and some scores carry their source's licence, named on each piece's page and on Credits. A piece may still be protected where you live; using it there is your call.

Fair use of the site

Don't try to break into accounts or the site, overload it, or copy it wholesale by script. Each page and the widgets for your site may be linked to and shared.

As it is

Clefsight is offered as it is and as available. We work to grade fairly and keep the scores right, but we can't promise it is free of mistakes or always reachable.

Liability

To the extent the law allows, Buretto Technologies Inc. is not liable for indirect or consequential loss from using Clefsight. Nothing in these terms limits rights you have as a consumer that the law says can't be limited.

Copyright notices

If you believe something on Clefsight infringes your copyright, send your notice of claimed infringement to our designated agent: Copyright Agent, Buretto Technologies Inc., 422 Richards St, Suite 170, Vancouver, BC V6B 2Z4, Canada. Phone 778-819-5020. Email hello@buretto.com.

Law

These terms are governed by the laws of British Columbia and of Canada that apply there.
