The following End User License Agreement (“EULA”) constitute an agreement between KAI OS TECHNOLOGIES (HONG KONG) LIMITED, including its affiliates (“we” or “KAI”) and you, and governs your use of Software and Services. Please read this EULA carefully. Please note that you must have the legal right to enter into agreements of this nature in order to use the Software and Services.
You agree to this EULA by using the software named “KaiOS”, including updates, upgrades, any additional and incorporated components, any software (including internet-based software), applications, content or Services KAI makes available pursuant to this EULA, and all software documentation (“Software”).

Note that certain components of our Software are available as open source via various projects (“Open Source Software”). Although the Software is subject to this EULA, Open Source Software is available under its own terms, subject to which you are free to use it in accordance with its terms.

In addition to Open Source Software, the Software can include other third-party software under separate licenses (which, together with Open Source Software are referred to as “Third Party Software”). These Third Party Software can be subject to different license terms which you must accept in order to be able to use them.

By accepting this EULA or using the Software and/or Services, you agree to all of these terms, and consent to the transmission of certain information during activation and during your use as per the KaiOS Privacy Policy in Section 2.


The Software and any content accessed through the Software are licensed, not sold. In consideration of your compliance, this EULA only gives you rights to use and run one instance of the Software on your device in which this Software is preinstalled. You may not distribute or make the Software available over a network where it could be used by multiple devices at the same time. KAI, its suppliers and licensees reserve all other rights. Unless otherwise stipulated by applicable law or Third Party Software licensing terms, you may use the Software only as expressly permitted in this EULA. In doing so, you must comply with any technical limitations in the Software that only allow you to use it in certain ways. You shall not:

• duplicate, distribute or modify the Software or publish the Software;
• work around any validation check or technical limitations in the Software;
• Use the Software for any illegal, fraudulent or unauthorized purpose;
• Transmit any worms or viruses, or any code of a destructive nature;
• Provide us false or misleading information;
• Collect from any third parties any personal data or personally identifiable information in violation of any data protection and/or privacy laws;
• reverse engineer, decompile or disassemble the Software, except and only to the extent that applicable law expressly permits, despite this limitation; or
• transfer the Software or this EULA to any third party unless along with the device containing the Software.

If we, in our reasonable discretion, consider that you are violating any laws, the terms of the license or this EULA, we reserve the right to, in addition to any other remedies available, suspend your access to the Software and Services.


Some of the Software and Services may send or receive information when activating or using them. By accepting this EULA and using the Software and/or Services you agree that we may collect, use, and disclose the information as described in the KaiOS Privacy Policy.


The Software may be subject to the export control laws and regulations of United States of America or other countries which may restrict or prohibit the export, re-export or transfer of the Software. You must comply with all applicable export and re-export control laws and regulations. For addition information or inquiry, please contact our customer service.


This EULA, the KaiOS Privacy Policy and the terms accompanying any Software updates, upgrade and Services that you use, are the entire agreement for the Software.

Because we are constantly developing our Software, we need to reserve the right, at any time and our sole discretion, to change the terms of this EULA. When we do so, we will use our reasonable efforts to notify you of what we have done.


In the event a dispute arises between you and us, please email to our customer service so we can attempt to resolve it promptly.

This EULA is governed by the laws of Hong Kong without reference to its conflict of law or choice of law principles. If you acquired the Software in the United States of America, the laws of the state where you live govern all other claims, including claims under state consumer protection laws, unfair competition laws, and in tort.

Any translation of this EULA is done for local requirements and in the event of a dispute between the English and any non-English versions, the English version of this EULA shall govern, to the extent not prohibited by local law in your jurisdiction.

If for any reason a court of competent jurisdiction finds any provision, or portion thereof, to be unenforceable, the remainder of this EULA shall continue in full force and effect.
