12. Governing Law & Jurisdiction

Governing Law

These Terms are governed by and construed in accordance with the laws of the People's Republic of China, without regard to its conflict of law principles. However, we acknowledge that many users are located outside China.

International Considerations

For users in the European Union, European Economic Area, United Kingdom, or other jurisdictions with mandatory consumer protections:

• Mandatory consumer protection laws in your jurisdiction may apply to these Terms regardless of the choice of Chinese law
• Nothing in these Terms waives rights that cannot be waived under your local laws
• You retain all statutory consumer protections applicable in your country or region

United States Users

For users in the United States, while these Terms are governed by Chinese law, certain US laws (such as COPPA and CCPA) may apply to the extent your use involves data collection or activities subject to those laws. Consumer protection laws in your state or jurisdiction may also apply.

13. Dispute Resolution & Arbitration

Informal Resolution

Before initiating formal dispute resolution, you and TechChatLab agree to attempt informal resolution:

• Contact us at support@techchatlab.com with a detailed description of your dispute
• We will make good faith efforts to resolve the matter within 30 days
• If resolution is not possible, you may pursue formal remedies

Arbitration Agreement

For users outside the EU/EEA and certain other jurisdictions with arbitration-prohibiting laws:

• Arbitration will be conducted by a neutral arbitrator in accordance with the rules in effect at the time of the dispute
• The arbitrator will make a final and binding determination

Class Action Waiver

You agree not to bring claims on behalf of a class or in consolidated proceedings with other users. Disputes must be resolved individually.
