Terms of Service

The short version

Using Folio

You may use Folio on the devices your App Store account permits, for as long as you like, for personal or professional music-making alike. There is no account to register and no seat to license.

What you may not do is the short and obvious list: take the app apart to redistribute it, resell it as your own, or use it to break the law where you are.

Purchases

Folio Pro is sold by Apple, not by me. It is a one-time purchase rather than a subscription: bought once, it stays with your Apple Account and follows you to a new device.

Refunds are Apple's to give, through reportaproblem.apple.com. I cannot issue one, because I never received the payment. If a purchase went wrong, write to me anyway — I would like to know, and I can usually tell you what happened.

What Folio Pro unlocks may grow over time. It will not shrink: features you have paid for do not get taken back out and sold again.

Your files, and your right to them

The music you import stays yours. Nothing in these terms gives me a licence to it, and nothing in the app sends it to me.

You are responsible for having the right to the files you bring. Folio does not inspect your library, does not judge what is in it, and could not do either if it wanted to — there is no server, and your library never leaves your devices and the cloud accounts you chose. Where a score arrives with licence information attached, Folio shows it to you, because that is information you need; it does not decide on your behalf what you may then do with it.

Services Folio can talk to

If you connect Google Drive or iCloud, you are also using those services under their terms, and they may change them without asking me. Folio asks each of them for as little as it can — the detail is in the privacy policy — but it cannot promise that somebody else's service will keep working, keep its prices, or keep existing.

What Folio does not promise

Folio is provided as it is, without warranty of any kind. I have tested it on real devices with real scores and I use it myself, but I cannot promise it is free of faults, that it will suit a particular purpose, or that it will never lose data.

Keep your own backups of music that matters to you. That is true advice for any app on any device, and it is the sentence in these terms most likely to save you something.

Limits

To the extent the law allows, I am not liable for indirect or consequential loss arising from your use of Folio — a missed cue, a lost annotation, a performance that went badly. Where liability cannot be excluded, it is limited to what you paid for the app.

Nothing here takes away rights your local consumer law gives you. If a term here conflicts with a protection you have as a consumer where you live, that protection wins.

Changes

Folio will change — that is what a maintained app does. If these terms change materially, the date below changes with them, and the page's history is kept alongside the app's source. Continuing to use Folio after a change means the new terms apply.

I may stop publishing Folio, or a service it connects to may stop existing. Music already on your device stays on your device: Folio stores your scores as ordinary files and does not hold them hostage to a licence check it might one day fail to make.
