Terms of Service

Last updated: 2026-11-03

These terms govern your use of bandcue, provided by Gabriele Proietti Mattia. That is three things and they are covered by one set of terms:

• the Android app (name.gpm.bandcue), from Google Play or from the self-hosted repository;
• the web app at https://bandcue-app.gpm.name, which is the same account and the same library as the phone app, in a browser;
• the connector for assistants at https://bandcue-app.gpm.name/mcp, through which an AI assistant you connect reads your cloud library and, if you allow it, changes it.

Installing or using any of them means you accept them. If you do not, do not install the app — and uninstall it if you already have — do not sign in to the web app, and do not connect an assistant.

What bandcue is

bandcue displays chord sheets you put into it, scrolls them at a speed you set, transposes them, and — if you point it at one — reads and writes them as files in a folder you already sync. It runs on your device.

It is not a catalogue. bandcue supplies no songs, hosts none and fetches none on your behalf. There is no library of anybody else’s material in it or behind it, and nothing is downloaded in the background — a search you type opens one page of that site in a view on your phone, and what you keep from it is kept in your library and nowhere else.

The songs are yours, and so is the responsibility for them

This is the most important paragraph on this page.

Lyrics and the chord arrangements over them are, in most cases, somebody’s copyright. What you may do with a copy — make one for your own use, print it, keep it, share it with the people you play with — is decided by the law where you are and by the terms of wherever you got it, not by this app.

So, plainly:

• You choose what goes in. Every song in your library arrives because you pasted it, opened it, typed it or shared it in. bandcue never obtains one on your behalf.
• You are responsible for having the right to keep and use what you put in, including for anything you place in a shared folder, where you are the one distributing it.
• The “search a chord site” button opens a browser view inside the app, on their site, under their terms and over your own connection. It used to hand off to your browser and take a share back, and this page still said so: what happens now is that you type a search, the app loads that one page in a view on your phone, reads the results and draws the list itself, and loads the one page you pick. Nothing is fetched before you ask for it, nothing is crawled, no catalogue is kept, and nothing is stored anywhere until you press keep — but the reading and the drawing are the app’s, and saying otherwise would be describing an older version of it. What you do on their site is between you and them.

• A takedown is not something the app can perform. Your files are on your device and in the folder you bound, and nobody reaches those from here.

  The cloud library is the exception, and it is yours to answer for. If you use it, the sheets and backing tracks you put in it are held on a server run by Gabriele Proietti Mattia, as you typed them, and can be read there. Nothing about them is public and no library is listed or searchable across accounts — but a copy exists off your device, and a request from whoever holds the rights to a song can be acted on there. See “The cloud library and the web app” below.

The cloud library and the web app

Both are optional, and neither changes what bandcue is: a library you filled yourself.

• What the cloud library is. A backup and a sync of your own library, under your account. Your sheets are stored as you typed them on a server run by Gabriele Proietti Mattia, which means the service can read them. They are not public, not indexed, not searchable across accounts, and have no share links; no account can see another’s. What you can share is bounded: a band you name, whose members you invite one at a time.
• What the web app is. The same account and the same library, in a browser, at https://bandcue-app.gpm.name: songs, setlists, bands and your account, and the sheet on a stand (capo, a page-turner pedal, a setlist played through, a tuner, a MIDI backing track), but not the band’s stage sync. It reads and writes the cloud library and nothing else — it never touches the folder on your device.
• Making and changing songs needs Pro; reading and export do not. Pro is on your account, so it is the same on the phone and in the browser.
• You are responsible for what you put in it, in exactly the way you are for what you put in a shared folder — including having the right to keep it and to let the people in your band read it.
• A backing track on a band’s song is the whole band’s. Every member can play it, download it and change it, as they can the sheet. By putting one there you confirm that you have the right to keep it and to let the members of that band use it, and the responsibility for that is yours. Someone who holds the rights to a track can ask for it to be removed by writing to apps@gpm.name, and the operator can delete it.
• You can take it back. A song can be deleted, and closing your account deletes what you kept under it. What is deleted is gone; there is no copy kept for you.
• It is a personal project, not an archive. Keep your own copies. The app holds the whole library on the device whether or not the cloud is on, and that is the copy to rely on.

Assistants

• What it is. An optional way into your cloud library for an AI assistant you choose — Claude, ChatGPT, the assistant in an editor — through bandcue’s connector. It is part of Pro, reading included, and you decide on bandcue’s own page whether the assistant may only read or also change. It never reaches your phone or your folder. How it works is on its own page.
• The assistant is not bandcue. It is somebody else’s software and service, used under its provider’s terms. Gabriele Proietti Mattia does not run it, does not control what it says, does or keeps, and is not responsible for its answers or its mistakes. What it reads from your library is sent to its provider; the Privacy Policy says what that means.
• What it does with your access, you do. A song it adds, changes or deletes, a setlist it makes, a note it writes is yours, exactly as if you had done it in the app — including in a band, where the other members see it as your change. bandcue tells an assistant to ask you before changing or deleting anything, and refuses a change made on a version of a song that is no longer the current one, but neither is a guarantee: read what it proposes before you let it act. A deletion is a deletion, and there is no copy kept for you.
• The songs are still yours to answer for. Letting an assistant read a song — yours, or a band’s — makes a copy of it available to its provider. You are responsible for having the right to do that, under the law where you are and the terms you got the song under, as you are for anything you put in a shared folder.
• Use it for your own library and your bands. Do not use the connector to collect material from the service in bulk — for a dataset, a model or anybody’s catalogue — to reach what your account cannot, to get round its limits, or to make the service fetch anything from anywhere. The connector answers a limited number of calls a minute and refuses past that.
• You can disconnect it at any time, from Connected apps on your account page in the web app, and it stops at once. The operator may refuse or disconnect an assistant that misuses the service, and blocking an account disconnects every assistant it connected.

Notifications

When another member changes something in a band you belong to, bandcue may tell you, by a notification on your phone (Play version), in a browser you chose, or by e-mail. That is part of the service; it is on by default and you can switch each channel off in Settings. Every e-mail carries a one-click unsubscribe. What a notification contains, and how it is delivered, is in the Privacy Policy. Notifications are a convenience and not a promise that you will be told, or told in time: look at the band before you rely on a change.

Licence

You get a personal, non-exclusive, non-transferable, revocable licence to use the app on devices you own or control. You may not sell, rent, sublicense or redistribute it, and you may not remove or alter attribution or notices in it.

Where the source code is published, its own licence governs the code — these terms cover the distributed app, not the repository.

No warranty

The app is provided “as is” and “as available”, without warranty of any kind, express or implied, including merchantability, fitness for a particular purpose and non-infringement. It is a personal project, not a commercial product with a support obligation.

On a stage, it is still a phone

bandcue is built for the moment it matters: the sheet works with the radios off, the screen stays on while one is open, and the scroll keeps its own clock. These are properties of the app, not promises about your device. A phone that runs out of battery, is killed by a manufacturer’s battery manager, rings, overheats or is dropped will stop showing you a chord sheet, and no software here prevents that. Bring paper for the set you cannot afford to lose.

What is outside anyone’s control

• What a sync provider does with your folder. Whether a change reaches the rest of the band, when, and what happens when two people edit one song is your provider’s behaviour. bandcue writes one file per song and never resolves a conflict for you, precisely because that decision is not this app’s to take.
• What a chord site’s text contains. The parser reads two dialects and keeps the original either way; a sheet that is wrong where it came from is wrong here too.
• Chord diagrams are a reading aid. They are drawn from ordinary shapes and the app declines to draw one it would be guessing at, but no diagram is a substitute for your own ear.

Acceptable use

Do not use the app unlawfully, and do not use it to store or distribute material you have no right to. Do not attempt to make it fetch material from a service that does not permit it — the app is deliberately built not to, and working around that is outside these terms.

Blocked accounts

bandcue’s operator can sign an account out everywhere, close it, delete a band — for example on a request from a rights-holder — delete a picture or a backing track, and block an account. An account can be blocked for abuse or for breaking these terms, meaning what “Acceptable use” above describes. A blocked account cannot sign in, and loses every assistant it connected. So that a block survives closing the account and signing up again, its addresses and Google sign-in are kept only as one-way hashes; unblocking removes them. The Privacy Policy says what the operator can and cannot see.

Requests to the service are rate-limited per IP address, and an address that keeps going over the limit, or keeps asking for pages that do not exist, is blocked for a day at the network edge.

Paid features

Some features may be offered as a paid unlock, through Google Play Billing in the Play version. Prices, currencies and taxes are shown by the store at the moment of purchase, and refunds follow Google Play’s own policy. What is sold is the making and changing of songs, and connecting an assistant, on your account — never songs, and never access to anybody’s catalogue. Reading and export are never paid, on the phone or in the web app; an assistant’s reading is part of connecting one. Whatever is available free today stays free for installs already using it. The version distributed outside Google Play contains no purchases and no cloud library of its own to sell.

Limitation of liability

To the maximum extent permitted by law, Gabriele Proietti Mattia is not liable for any indirect, incidental, special or consequential damages, nor for any loss arising from a sheet that failed to display, a scroll that ran at the wrong moment, a song that could not be read, a file written into or missing from a folder, anything an assistant you connected read, said, added, changed or deleted, or any claim arising from material you chose to put into the app.

Nothing here excludes liability that cannot lawfully be excluded, including liability for death or personal injury caused by negligence, or for fraud. Consumers keep their mandatory statutory rights, which these terms do not limit.

Availability and changes

The app, the web app, the connector and the service behind them may be modified, suspended or discontinued at any time, and these terms may be updated; the current version always lives on this page, with the date below. Continuing to use any of them after a change means you accept it.

Governing law

These terms are governed by Italian law. If you are a consumer, you keep the protection of the mandatory provisions of the law of your country of residence, and may bring proceedings in the courts there.
