1. Overview

This policy explains what data this website (www.yujuenv.com, operated by YUJU EnvironTech) processes, which cookies are used, and how you can change or withdraw your consent. This website does not use advertising or re-marketing cookies. Analytics measurement runs on Google Analytics 4 (Measurement ID: G-07GXMQ55R3) and is activated only after you give consent.

2. Cookies we use

Strictly necessary storage: your cookie preference itself is saved in your browser's localStorage (key: yuju_cookie_consent). It contains only your choice and a timestamp, is not sent to any server, and expires automatically after 180 days.

Analytics cookies (set by Google Analytics 4, only after consent):

- _ga — distinguishes visitors; stored for up to 24 months;
- _ga_* — maintains session state; stored for up to 24 months.

Before you consent, no analytics cookies are set and no measurement requests are sent. If you reject or withdraw consent, the GA4 cookies previously set by this site are deleted from your browser.

3. Data processed by Google Analytics 4

When analytics is active, Google Analytics 4 collects technical usage data such as pages viewed, time on page, referrer, device/browser type, screen resolution and an approximate location derived from your IP address. Google Analytics 4 does not store your full IP address. We do not send Google Analytics any name, email address or other identity data you submit through forms on this site.

The data is processed by Google LLC under the Google Analytics Terms of Service and the Google Privacy Policy. Data may be transferred to and processed in the United States or other countries where Google operates. Data retention on the Google side follows the data-retention setting configured in our Google Analytics property.

4. Managing your choice

You can accept, reject or change analytics consent at any time:

- click "Cookie Settings" at the bottom-left corner of any page, switch "Analytics cookies" on or off and save; or
- clear your browser data / use your browser's private mode.

Withdrawing consent stops further measurement on this site and deletes the GA4 cookies set by this site. It does not affect data already transferred to Google before your withdrawal.

5. Data you submit to us

Information you send us directly (contact forms, email, WhatsApp or phone) is used only to answer your enquiry and is not used for automated profiling. Enquiry data is handled by our staff and is not sold to third parties.
