Effective July 9, 2026.
MusicianOS ("the app") is operated by Tipping Maples LLC, a Minnesota limited liability company ("Tipping Maples," "we," "us"). By downloading or using the app, you agree to these Terms. If you do not agree, do not use the app.
MusicianOS is two things, and your rights differ between them.
The app (Free, Plus, Pro). Your songs, charts, lyrics, recordings and files live on your device and in your own private Apple iCloud account. We do not receive them, store them, or have any means of reading them.
The Pro+ web platform (muos.app). Content you choose to publish to a public artist page is hosted on servers we operate, is publicly visible, and is governed by the Acceptable Use Policy, the DMCA Policy, and the Repeat Infringer Policy. Your use of the muos.app web features is also governed by the muos.app Terms of Service, and the data they involve is described in the muos.app Privacy Policy.
Where these Terms speak of “your content,” they mean the second — what you publish to muos.app. We claim nothing over the first.
The app is licensed, not sold. Your use of the app obtained from the Apple App Store is also subject to Apple's Licensed Application End User License Agreement (the "Apple Standard EULA"). To the extent these Terms and the Apple Standard EULA conflict for App Store usage, the Apple Standard EULA governs that conflict.
MusicianOS is free to download and use within the limits shown in the app. Optional auto-renewable subscriptions (MusicianOS Plus, MusicianOS Pro, and MusicianOS Pro+) unlock additional features. Subscriptions are sold and billed by Apple through your Apple Account; payment, renewal, and cancellation are managed in your Apple Account settings and are subject to Apple's terms. A subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Promotional offer codes, where offered, are redeemed through Apple.
Pro+ web platform. Pro+ additionally unlocks the MusicianOS web platform at muos.app (web library editing, a public artist page, bookings, live audience requests, tips, and a newsletter).
You keep all rights to the songs, lyrics, recordings, and other content you create, import, or store in the app. That content is stored on your device and in your own private Apple iCloud account — not on our servers — and this stays true on Pro+: your song content is never kept on our servers. You are solely responsible for having the rights, permissions, and licenses necessary for any content you import, store, share, publish, or export. Do not use the app to infringe anyone's copyright or other rights. See our Copyright Policy.
You retain all rights in what you publish to a muos.app artist page. You grant Tipping Maples LLC a worldwide, non-exclusive, royalty-free licence to host, store, reproduce, adapt for display, and publicly display and perform that content solely to operate, provide, and promote the service, for as long as you keep it published.
Unpublish it and the licence ends, save for copies retained in routine backups for a limited period and copies we must retain by law.
We take no ownership. We do not use your music to train models. We do not license it to anyone else.
By publishing content you confirm that:
Performing a cover live does not give you the right to publish someone else’s chart, arrangement, lyrics, or recording of that song. Those are separate rights.
Don't use the app to break the law, infringe others' rights, or attempt to disrupt or reverse-engineer the app except where that right cannot be limited by law. What you may publish to a Pro+ artist page, and messages you send through the platform, are governed in full by the Acceptable Use Policy.
We may, at our discretion:
where we reasonably believe there has been a violation of these Terms, the Acceptable Use Policy, the Repeat Infringer Policy, or the law — or where required by a court or competent authority.
We will normally give notice and a chance to respond. We may act immediately and without prior notice where the content is unlawful, where there is an active infringement claim, where there is a security threat or a risk of harm, or where notice is prohibited or would frustrate a court order.
Repeat copyright infringement leads to termination under the Repeat Infringer Policy. That policy is not discretionary window dressing: 17 U.S.C. §512(i) conditions our safe harbor on implementing it.
What termination does not do. It does not reach your device or your private iCloud library. Your songs, charts, recordings and files remain yours and remain where they are. The MusicianOS app continues to function at the Free tier, and you may export your library at any time. We can take you off the public web; we cannot take away your music, because we never held it.
You may terminate at any time by cancelling your subscription and deleting your account — from within the app, or at muos.app.
We are not your backup. For the app, your content lives in your own iCloud account under Apple’s terms, and its preservation, availability, and security are matters between you and Apple. We cannot restore what we never had.
For the Pro+ platform we take reasonable technical and organisational measures to protect content you publish, but we do not warrant that content will never be lost, corrupted, or unavailable, and we do not undertake to retain it.
MusicianOS provides an export and full-backup facility. Use it. Keep your own copies of anything you would be upset to lose. Where a backup file cannot carry every referenced recording or document, the app tells you so at the time — read that warning rather than assuming.
Artist pages, booking enquiries, live audience song requests and tip notes are created by users, not by us. We do not review them before they appear. We are not the author or publisher of user content and do not endorse it.
We are not responsible for user content, for anything you rely on in it, or for dealings between you and any artist, venue, or member of the public who reaches you through the service — including bookings and payments. That is between you and them.
Optional features connect to third-party services under their own terms: Apple iCloud (sync); Apple iTunes Search and Datamuse (metadata and word lookups); your chosen AI provider (only if you add your own key); and streaming/lookup links (Apple Music, Spotify, YouTube). We are not responsible for third-party services.
The service is provided “as is” and “as available,” without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, non-infringement, and any warranty of uninterrupted or error-free operation. We do not warrant that data will never be lost — keep your own backups (the app can export them at any time).
To the fullest extent permitted by law, Tipping Maples LLC will not be liable for indirect, incidental, special, consequential, exemplary or punitive damages, nor for loss of profits, revenue, data, goodwill, or musical or business opportunity, however caused.
Our aggregate liability arising out of or relating to the service is limited to the greater of (a) the amounts you paid us in the twelve months before the event giving rise to the claim, or (b) one hundred United States dollars.
Nothing in these Terms excludes or limits liability that cannot lawfully be excluded or limited — including liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any liability that the consumer-protection law where you live does not permit us to exclude. If you are a consumer in the European Union or the United Kingdom, you have statutory rights that these Terms do not affect.
You will indemnify and hold harmless Tipping Maples LLC, its officers, and its agents against claims, damages, liabilities, and reasonable legal costs arising out of content you publish, your use of the service, or your breach of these Terms or of any law or third-party right.
We will notify you of any such claim, let you control the defence with counsel reasonably acceptable to us, and cooperate at your expense. You may not settle a claim in a way that admits our fault or imposes obligations on us without our written consent.
We may change these Terms. Material changes will be notified by email or in the app before they take effect. Continuing to use the service after that constitutes acceptance. If you do not accept, stop using the Pro+ platform and cancel; the app continues to work at the Free tier.
These Terms are governed by the laws of the State of Minnesota, USA, without regard to its conflict-of-laws rules.
