Desktop Privacy Policy

Below is our new privacy policy for MuseScore 4. There are two important aspects to this privacy policy. First, that we are compliant with national and international regulations, namely GDPR and CPPA. Secondly, that we are transparent with our users and our developer community about the data we collect, when we collect it and why. The most important point stressed throughout the document is that we do not store or share any of your personal information.

There are two relevant networking features mentioned in the privacy policy:

Update Checking

Update checking is where we notify users when there is a new version of MuseScore available. The user is notified when MuseScore is first installed and is provided with a clear link to disable it in Preferences. Update checking shares your IP address, your OS, and your MuseScore version (including whether MuseScore was compiled in 32 or 64 bit mode). As explained in the privacy notice, we take steps to anonymise your IP address immediately, which makes it impossible for us to identify you. Please note that we also use this anonymised information for statistics, which help us understand how many users we have per country, which version of MuseScore they are using, and whether it is run on Windows, Mac or Linux. These statistics help us to plan app development and make decisions about which platform versions we need to support, etc.

Error Reporting

The other networking feature in MuseScore is error reporting. If an application error occurs, a popup appears asking you whether you want to send us the details of that error, which you can review before sending. We have taken steps to ensure that all potentially identifiable information is filtered from the report data before storage, including the IP address, which we discard.

Please note that some of the terminology in the privacy notice is potentially confusing to those without a legal or technical background. For example, under the section titled ‘Principles of Processing’, the last point (F) states: “We use appropriate technical and organisational measures to protect the personal information that we collect and process about you”. It is worth taking a moment to explain what this means: first, the ability to send any information over the internet requires an IP address, which is classified under CCPA & GDPR as ‘personal information’. As with any application that makes use of a network connection, we cannot avoid seeing (“collecting”) an IP address. Lastly, the steps we take to anonymise it counts as ‘processing’.

Please note that since this is a draft privacy policy, it does not yet apply to any version of MuseScore that has been released and we will alter its wording based on your feedback to make sure it is as clear as possible before publishing the final version.

The notice below outlines:

  • The very limited data we collect and why we collect it
  • Your options in sharing or not sharing information with us
  • Your rights in managing information you share with us
  • Our responsibilities in protecting the data we collect and process

    Thanks very much,
    The MuseScore team

    MuseScore Desktop Privacy Policy

    As a responsible organisation, we have taken two important steps. First, we have made sure that we have, at the discretion of our users, the information necessary to allow us to improve the Musescore desktop application, and that by doing so we are compliant with national and international regulations, namely GDPR and CCPA. Second and most important: we have been, and will continue to be, transparent with our users and our developer community about the data we collect, when we collect it and why. We will also publish any intended changes before they are implemented in all newer versions of the Musescore application.

    Musescore is free and open source software, which means that the program’s source code is publicly available and can be inspected to confirm the very limited data that gets sent. You can also inspect our release executable files using network analysis tools.

    Your privacy rights

    Under the GDPR, individuals have certain data protection rights, which you can exercise by emailing However, these rights only apply to the extent that the controller is able to identify the individuals whose personal information is collected. As mentioned above, the Musescore Team anonymise or discard information that would enable us to identify you, and the processing of the information we collect does not require us to identify you. For these reasons, the exercise of your GDPR rights may be limited, or in some cases, might not apply.

    • obtain access to the personal information held about you - under Article 15 of the GDPR, individuals have a right of access that gives them the right to ask companies to confirm whether their personal information is being processed by them and if that is the case, the right to obtain a copy of their personal information, as well as other supplementary information. It helps individuals to understand how and why companies are using their information, and check the lawfulness of the processing.
    • ask for incorrect, inaccurate or incomplete personal information to be corrected - under Article 16 of the GDPR, individuals have the right to have inaccurate personal information rectified. An individual may also be able to have incomplete personal information completed – although this will depend on the purposes for the processing.
    • request that personal information be erased when they are no longer needed or if processing is unlawful - under Article 17 of the GDPR, individuals have the right to have personal information erased. This is also known as the 'right to be forgotten'. The right is not absolute and only applies in certain circumstances.
    • request the restriction of the processing of your personal information in specific cases - Article 18 of the GDPR gives individuals the right to restrict the processing of their personal information in certain circumstances. This means that an individual can limit the way that an organisation uses their information. This is an alternative to requesting the erasure of their information.
    • receive your personal information in a machine-readable format and send them to another controller ('data portability') - under Article 20 of the GDPR, individuals have the right to data portability that gives individuals the right to receive personal information they have provided to a controller in a structured, commonly used and machine readable format. It also gives them the right to request that a controller transmits those data directly to another controller.
    • lodge a complaint with a supervisory authority - In accordance with Article 77 of the GDPR, you, as a data subject, have the right to lodge a complaint with a supervisory authority, in particular in the Member State of your habitual residence, place of work, or where an alleged infringement of the GDPR has taken place. The contact details of European supervisory authorities are available here.
