Terms of use

Last updated October 11, 2026. NoteComet is run by VGJ LLC (“we”).

What NoteComet is

NoteComet shows the notes of a piece of music falling onto a piano keyboard, so you can learn to play it. You add the music yourself: a MusicXML or MIDI file, or a photo or PDF of sheet music that NoteComet reads for you.

Your account

• You sign in with your email address. Keep access to that mailbox safe, because anyone who can read it can sign in as you.
• You must be at least 18, or have a parent or guardian set up and manage the account for you. Children are welcome to play with a grown-up's account.
• You can delete your account at any time from the Account screen.

Your music

• Only add music you have the right to use: music you own a copy of for your own practice, public-domain music, or music whose owner allows it.
• Your library is private. NoteComet never shows your pieces, photos or files to anyone else, and has no way to share them.
• You keep all rights to what you upload. You let us store it and process it only to run NoteComet for you.
• If you believe something stored in NoteComet infringes your copyright, write to [email protected] with enough detail for us to find it. We will remove infringing material and close the accounts of repeat infringers.

Free pieces

The free library holds music that is in the public domain or shared by its editors under an open licence; each piece names its source and licence. Anyone may play it, with or without an account. If you believe a piece shouldn't be there, write to [email protected] and we will take it down while we look into it.

Reading photos and PDFs

Reading sheet music is done by software and is not perfect. Check what it read, and use the review screen to fix anything it got wrong. A read that fails doesn't count against your monthly reads.

Plans and payment

• Free doesn't include photo or PDF reads — that is a Pro feature. Importing MusicXML and MIDI is free and unlimited. NoteComet Pro includes a monthly allowance of photo or PDF reads. Current limits and prices are on the Account screen.
• Pro is a subscription, billed monthly or yearly through Stripe. It renews automatically until you cancel.
• You can cancel at any time under Account → Manage billing. Pro then stays on until the end of the period you have paid for, and is not charged again. We don't refund partial periods, except where the law requires it.
• If we change the price, we will tell you by email before it applies to your next renewal, and you can cancel before then.

Fair use

Don't try to break, overload or get around the limits of NoteComet, access other people's accounts, or use it to store things that aren't music. We may suspend accounts that do.

No warranty

NoteComet is provided as it is. We work to keep it running and your library safe (it is backed up every night), but we can't promise it will always be available or error-free. To the extent the law allows, our total liability to you is limited to what you paid us in the 12 months before the claim.

Changes

We may update these terms. If a change matters, we will tell you by email or in the app before it takes effect. Questions: [email protected].
