Third-Party Websites and External Links
This Extension operates on specific websites (such as Gmail, WhatsApp, Facebook, etc.), but these websites have their own privacy policies. We are not responsible for the privacy practices of third-party websites. We recommend that you review their privacy policies when using these websites.

- Knowledge base management
- User dashboard access
- Other account-related services

When you click these links, you will be redirected to our official website, which is governed by our website's privacy policy and terms of service. The Extension itself does not automatically redirect you to external websites; all external navigation requires your explicit action (clicking a button or link).

Disputes and Applicable Law
The arrangements in this clause regarding applicable law and dispute resolution are intended to balance compliance needs for us (located in mainland China) and for overseas users. The specific rules are as follows:

If you are a user within the People's Republic of China, the interpretation and application of this policy shall be governed by the laws of the People's Republic of China
If you are a user outside the People's Republic of China, this policy does not deprive you of any rights you may have under mandatory local consumer protection laws. Without violating mandatory local laws, both parties shall first attempt to resolve disputes through friendly negotiation; if negotiation fails, unless otherwise mandatorily required by the laws of your region, you agree to submit disputes to the Singapore International Arbitration Centre (SIAC) for arbitration in English in accordance with its arbitration rules, with Singapore as the seat of arbitration
For individual small claims not suitable for arbitration, you may still bring proceedings in a court with jurisdiction in your place of residence

This clause also does not affect the priority protection of users under any applicable mandatory legal provisions (such as consumer protection laws).
