Terms of Use for MustardOS (muOS)

MustardOS, often referred to as muOS, is a custom firmware developed for specific hardware and use cases. Both MustardOS and muOS are valid names for the project, with muOS being a shortened version. By downloading, installing, or using MustardOS/muOS, you agree to the following terms of use:

1. Discouragement of Third-Party Distribution

MustardOS/muOS is intended for personal use only and should not be distributed by third-party businesses or individuals without explicit permission. We strongly discourage any company or individual from selling devices pre-installed with MustardOS/muOS, as third-party modifications may affect the performance or stability of the firmware.

2. Support for Third-Party Devices

While we provide support to all users, including those who have obtained MustardOS/muOS through third parties, our official stance is that any user experiencing issues must reflash their device using an official download from our website or authorised platforms. We cannot guarantee the integrity or functionality of any modified versions from third-party sources, and reflashing ensures you are running a clean, supported version of the firmware.

Please ensure you have backed up your data before reflashing, as it may erase existing data. Detailed instructions for safely reflashing your device can be found on our official website or GitHub repository.

3. Risk of Third-Party Copies

Any copies of MustardOS/muOS obtained through third parties (other than official sources) are acquired at your own risk. We cannot guarantee the integrity, functionality, or safety of such copies. The MustardOS/muOS development team accepts no responsibility or liability for any harm, damage, or performance issues caused by third-party versions of the firmware.

4. Official Downloads

To ensure you have a legitimate and secure version of MustardOS/muOS, always download the firmware directly from our official website or authorised platforms. Only these sources can guarantee the authenticity of the software and provide official support.

5. No Copyrighted Material Supplied

The MustardOS/muOS team does not provide or distribute any copyrighted material, including game content (referred to as ROMs) or hardware BIOS files. Users are responsible for sourcing any ROMs or BIOS files independently and legally. It is the responsibility of the individual user to ensure that they comply with local laws regarding the use of copyrighted content.
