This privacy statement is intended to help you understand what data we collect, how and why we collect it and how we use it. However, this Policy only applies to Maxthon's browser products and our own websites.

This is important. We hope you take time to read it carefully.

How do we protect your information?

We are committed to protecting your data once we have it. We implement physical and technical security measures designed especially for that.

Despite our efforts, if we learn of a security breach, we'll notify you so that you can take appropriate protective steps. But over the 10 years of Maxthon's presence in this industry, there has NEVER been one privacy leak incident, not once.


Maxthon has strict restrictions on access to user data. Only a limited and restricted number of our employees has access to it. This also includes employees for our web hosting service providers.

Maxthon is a global company and our computers/servers are located in several different places around the world. We also use service providers whose computers may also be in various countries. This means that your information might end up on one of those computers in another country, and that country may have a different level of data protection regulation than yours. By giving us information, you consent to this kind of transfer of your information. No matter what country your information is in, we comply with applicable law and will also abide by the commitments we make in this privacy policy.


Procedures are reviewed regularly to ensure that the policies are followed. Any non-conformance regarding the policies will be corrected without unnecessary delay.
