Terms and Conditions


By downloading or using this application, these terms will automatically apply to you—so please make sure to read them carefully before using the app. You are not allowed to copy or modify the app, any part of the app, or our trademarks in any way. You are not permitted to attempt to extract the source code of the app, translate the app into other languages, or make derivative versions. The app itself, along with all trademarks, copyrights, database rights, and other intellectual property rights related to it, remain the property of Beijing Yihai Technology Co., Ltd.

Beijing Yihai Technology Co., Ltd. is committed to ensuring that the app is as useful and efficient as possible. Therefore, we reserve the right to make changes to the app or to charge for its services at any time and for any reason. We will never charge you for the app or its services without clearly explaining what you are paying for.

Zeal Particele stores and processes personal data that you have provided to us in order to deliver our services. It is your responsibility to keep your phone and access to the app secure. Therefore, we recommend that you do not jailbreak or root your phone, which is the process of removing software restrictions and limitations imposed by the official operating system of your device. Doing so could make your phone vulnerable to malware/viruses/malicious programs, compromise your phone’s security features, and may result in the app not working properly or at all.

The app does use third-party services that declare their own Terms and Conditions.

Links to Terms and Conditions of third-party service providers used by the app:

You should be aware that, in certain cases, Beijing Yihai Technology Co., Ltd. will not take responsibility. Some functions of the app require an active internet connection. This can be Wi-Fi or provided by your mobile network provider, but Beijing Yihai Technology Co., Ltd. cannot take responsibility if the app does not function fully due to lack of access to Wi-Fi or if you have no remaining data allowance.

If you are using the app outside of a Wi-Fi area, you should remember that your mobile provider’s terms still apply. As a result, your mobile provider may charge you for data usage during the connection while accessing the app or other third-party charges. In using the app, you are accepting responsibility for any such charges, including roaming data charges, if you use the app outside of your home region or country without turning off data roaming. If you are not the bill payer for the device you are using the app on, we assume you have received permission from the bill payer.

Similarly, Beijing Yihai Technology Co., Ltd. cannot always take responsibility for how you use the app. For example, you need to ensure your device stays charged—if it runs out of battery and you can’t turn it on to access the service, Beijing Yihai Technology Co., Ltd. cannot be held responsible.

Regarding the responsibility of Beijing Yihai Technology Co., Ltd. for your use of the app, it is important to remember that, although we strive to ensure that the app is updated and running properly at all times, we rely on third parties to provide information to us so that we can make it available to you. Beijing Yihai Technology Co., Ltd. accepts no liability for any loss, direct or indirect, you experience as a result of relying entirely on this app’s functionality.

At some point, we may wish to update the app. The app is currently available on [platforms], and the requirements for both systems (and for any additional systems we decide to extend the availability of the app to) may change. You will need to download updates to continue using the app. Beijing Yihai Technology Co., Ltd. does not guarantee that the app will always be updated to be relevant to you and/or compatible with the version installed on your device. However, you agree to always accept updates to the application when offered. We may also wish to stop providing the app and may terminate use of it at any time without notice. Unless we tell you otherwise, upon any termination, (a) the rights and licenses granted to you in these terms will end; (b) you must stop using the app and, if necessary, delete it from your device.


Changes to These Terms and Conditions

We may update our Terms and Conditions from time to time. Thus, you are advised to review this page periodically for any changes. We will notify you of any changes by posting the new Terms and Conditions on this page.

These terms and conditions are effective as of August 30, 2024.
