Privacy Policy

While you use our services, we may collect information you actively provide or that is generated by your use of the services, as follows:

1. Browsing and usage information: to display content and improve our services, we may collect records such as pages viewed, clicks, search keywords and time spent.

2. Device and log information: to keep the service secure and running properly, we may collect log information such as device model, operating system, browser type, language settings, IP address and access time. The IP address is also used to estimate your approximate region so we can automatically switch to the English interface for overseas visitors.

3. Information you submit: when you use the health tools (BMI, basal metabolic rate, calorie calculators, etc.), the values are used for instant calculation locally in your browser only; we do not actively collect or store this health data.

This site does not provide account registration or login, and generally does not collect directly identifying information such as your name, phone number or ID. If such features are launched in the future, we will obtain your consent separately.

To give you an easier browsing experience, we may use cookies or local storage (localStorage) to remember your preferences, such as your chosen language (Chinese/English). You can manage or delete cookies through your browser settings, but doing so may affect some features.

To analyze site traffic and improve the product experience, this site uses third-party analytics services, including Google Analytics and Baidu Tongji (Baidu Analytics). These services may collect anonymous visit data (such as page views, referral source and device information) via cookies or similar technologies. The processing of such data is governed by each provider's own privacy policy.

On certain promotional landing pages, we may use Baidu marketing conversion-attribution and advertising technologies to measure campaign performance. Except as required by law or authorized by you, we do not sell or rent your personal information to third parties.

We may share, transfer or disclose your information in accordance with the law in the following cases: (1) with your prior explicit consent; (2) to fulfill obligations under laws and regulations; (3) in response to lawful requests from judicial or administrative authorities; (4) to protect the lawful rights, property or safety of this site and its users.

We use industry-standard security measures to protect your information against unauthorized access, disclosure, use, modification, damage or loss, including encrypted transmission (HTTPS) and access controls.

Please understand that the internet is not an absolutely secure environment. We will do our best to keep your information safe but cannot guarantee it is 100% secure.

You can manage cookies through your browser settings, clear local storage, and opt out of third-party analytics (for example by installing the relevant browser add-on). You can also change your interface language preference at any time using the language switch on the page.

If you have any questions, comments or complaints about this policy or the handling of your information, please contact us using the details at the end of this page.

This site primarily provides health information services for adults. If you are a minor, please use this site under the guidance and accompaniment of a guardian, and provide information to us only with your guardian's consent.

We may revise this Privacy Policy from time to time. When changes are made, we will publish the latest version on this page and update the "last updated" date. Please review it periodically. Your continued use of this site after an update constitutes acceptance of the revised policy.

If you have any questions about this Privacy Policy or wish to exercise your rights, please contact us by email at support@combosm.com. We will respond as soon as possible after receiving your message.
