Affiliate: Refers to any company or other entity that directly or indirectly controls, is directly or indirectly controlled by, or is under common direct or indirect control with, the Company. “Control” and “controlled” mean the right to direct the management policies of a party through voting rights or other means.

II. Use of the Product

  1. Conditions of Use

Before using the Product, you should carefully read and agree to the Privacy Policy and this Agreement. When you launch the Product for the first time, the software will display a notice directing you to review the applicable agreements. If you do not agree, please stop using the Product and exit the application.

The current version of the Product is primarily intended for local use and does not require you to register for or log into an account to use its core music playback functions. If account functionality is introduced in a future version, the applicable product documentation will govern such functionality.

You shall comply with all applicable laws and regulations when using the Product and shall not use the Product for any unlawful or infringing purpose.

  1. Rules of Use

You represent and warrant that you have lawful rights to, or have obtained lawful authorization for, any music files and related content that you play, scan, import, or access through the Product. You are responsible for any consequences arising from copyright disputes, unlawful sources, or other rights-related defects concerning such content.

When configuring accounts or connection information for accessing network-based music resources, you shall ensure that you have lawful authorization to access the relevant servers and their content and shall properly safeguard your account credentials and passwords. You are responsible for access failures, data loss, or other losses caused by incorrect configurations made by you or by issues with the relevant servers themselves, except to the extent otherwise required by applicable law.

You understand and agree that functions such as local network device discovery and casting or playback to other devices depend on your network environment and the compatibility of the target devices. The Company does not guarantee compatibility with all devices, routers, or media servers.

III. Installation, Uninstallation, and Updates

You must select the version of the Product compatible with your device. The Company grants you a personal, non-transferable, non-exclusive, non-commercial license to use the Product. All rights not expressly granted to you under this provision or elsewhere in this Agreement are reserved by the Company. Any exercise of rights not expressly granted requires the Company’s prior written authorization. The Company’s failure or delay in exercising any such right shall not constitute a waiver of that right.

Installation and Uninstallation: You may download the Product from application stores, websites, or platforms authorized by the Company. If you obtain the Product or an installer bearing the same or similar name from an unauthorized third party, the Company cannot guarantee that the installer will function properly and, to the extent permitted by applicable law, shall not be responsible for losses resulting from such unauthorized downloads. The Company may develop different versions of the Product for different types of devices. You should select and install the version appropriate for your device. If you no longer wish to use the Product or wish to install a newer version, you may uninstall the Product yourself.

To improve the user experience and enhance the services, the Company will continue to develop new functions and may provide updates to the Product from time to time. Such updates may take the form of software replacement, modification, feature enhancement, version upgrade, or other changes. After a new version is released, you may be notified to download or install the update through in-app notices, application store updates, or other appropriate means. You may also check for updates manually through the “About” page.

IV. Product Services

  1. Method of Use

You may use the Product as a client application on mobile phones, tablets, music players, or other compatible devices, as supported by the Company. When using the Product, you should select the version compatible with your device, operating system, and other relevant specifications. Otherwise, the Product may not function properly.

  1. Services Provided by the Product

The Product primarily provides music playback and related functions and services, with the specific functions subject to those actually made available in the Product. The Company will use reasonable efforts to provide the relevant services. Different versions of the Product may provide different functions and services.

Where music files or other content provided by a user are unlawful, infringe third-party rights, violate applicable laws, or are otherwise inappropriate for processing, the Company may refuse to provide relevant processing functions or services to the extent permitted by applicable law.

Functions such as network-based music access and local network device discovery depend on network conditions. If such functions become unavailable due to network failures, changes to third-party services, device compatibility issues, or other circumstances beyond the Company’s reasonable control, the Company shall not be responsible for additional liability to the extent permitted by applicable law.

You should back up important music files, playlists, and configuration data. If data is lost due to reasons attributable to you, including but not limited to accidental deletion, device damage, system upgrades, changes to permissions, database resets, or similar circumstances, the Company does not provide data recovery services and shall not be responsible for such loss, except as otherwise required by applicable law.

Certain device-customized versions may hide or modify certain interface elements, such as an email contact option on the About page. This does not affect the validity of this Agreement or the Privacy Policy. You may still access the complete versions of these documents through the agreement links provided within the Product.

  1. Service Fees

The core functions of the current version of Surfans Music App are provided free of charge, and no software usage fee is currently charged. If paid functions or value-added services are introduced in a future version, the applicable product page or other relevant notice will govern.

When you use the Product to access network resources, third-party webpages, or online interfaces, your network service provider may charge you for data usage or other network services. Such charges are your responsibility and are unrelated to the Company.

To the extent permitted by applicable law, the ownership and other rights in music files and their metadata that you import, scan, or play through the Product (the “Input Content”), as well as playlists, settings, and other content generated through your use of the Product (the “Output Content”), remain with the original rights holder or otherwise remain subject to your lawful rights.

Unless otherwise provided in this Agreement, we will not publicly disclose or distribute the contents of your local music files to third parties without your permission.

Confidentiality: The Company will implement reasonable confidentiality and security measures and use reasonable efforts to protect your information from unauthorized access, use, or disclosure. Maintaining the security and proper operation of the service is a shared responsibility of the Company and its users. To the extent permitted by applicable law, the Company shall not be responsible for information disclosure resulting from circumstances beyond the Company’s reasonable control and not caused by the Company’s failure to exercise reasonable care, including natural disasters, theft, robbery, or cyberattacks.

VII. Advertising and Commercial Information
