Welcome to purchase products from our company (operating an electronics business in the United States). This policy aims to clearly define the copyright ownership and protection rules of our products and related content, strictly adhering to U.S. copyright law and the Berne Convention regulations, protecting the legal rights of both our company and users. If you have any questions, please contact our customer service at +86 19202338340. Our working hours are Monday to Friday, 9:00 AM to 6:00 PM (UTC+8:00).

1. Copyright Ownership

1. All electronic products (including hardware, associated software, firmware), product images, manuals, promotional copy, website content, and related intellectual property of our company are solely owned by us. These assets have completed copyright protection procedures and are strictly protected by U.S. copyright law.

2. The copyright for digital content such as product software, firmware, etc., including the right to copy, distribute, and communicate over information networks, belongs to our company. Unauthorized use, modification, or distribution is prohibited.

2. User’s Legal Usage Rights

After purchasing our electronic products through legitimate channels, users receive a legal right to use the product. Users are allowed to use the product and its accompanying software as described in the manual, for personal or lawful commercial use, without exceeding the reasonable scope of use. Specifically:

• Users can use all the features of the product hardware and accompanying software for daily use or lawful business activities.

• Users can copy the product manual, driver program, etc., for personal use or normal product maintenance but cannot use them for other purposes.

• Users can edit/change orders within 12 hours after order placement. Upon purchasing the product, users are entitled to normal after-sales protection. These usage rights do not involve the transfer of copyright.

3. Prohibited Actions

Without our written authorization, users are prohibited from the following acts of infringing on our copyrights. Violation of these rules will result in legal consequences:

• Unauthorized copying, modifying, cracking, reverse-engineering our product software or firmware, or extracting core technologies or source code.

• Unauthorized dissemination, sale, rental, or transfer of product images, manuals, promotional content, software copies, or other copyright-protected materials.

• Unauthorized use of our products and related content for infringing creations, commercial profit, or other illegal purposes.

• Any other violations of U.S. copyright law and related regulations that infringe upon our copyrights.

4. Copyright Protection and Enforcement

1. Our company has completed copyright registration for core products and related content. The copyright registration certificate can serve as preliminary evidence of ownership, which is used to protect our legal rights.

2. If any infringement of our copyrights is discovered, we will take legal actions, including but not limited to sending copyright violation notices, requesting cessation of infringement, compensation for damages, and filing lawsuits with judicial authorities if the violation is severe.

3. If users discover any infringement, they can contact our customer service to report it. We will promptly verify and address the issue.

5. Exceptions

1. After legally purchasing the product hardware, users may have the right to use and transfer the hardware. However, the copyright for the accompanying software still belongs to us. If transferring the hardware, the accompanying software must be transferred as well; the software cannot be copied or distributed separately.

2. Due to after-sales maintenance or software upgrades, our company has the right to modify or optimize the accompanying software. Such modifications will not affect the original copyright ownership.

3. Our shipping terms (orders in stock will be shipped within 1-2 business days, excluding weekends and holidays, and actual delivery takes 5-7 business days) do not affect the copyright ownership and protection of the product.

6. Policy Updates and Contact Information

This policy may be revised based on updates to U.S. copyright law or business needs. Updates will be published in a prominent location on our official website.
