Who runs this site
This site is run by EFY Intelligent Control (Tianjin) Technology Co., Ltd (“EFY”). This notice explains what the site does with information about you.
The contact form
When you send the contact form, the site’s own server sends what you entered as one email to EFY’s sales mailbox: your name, organization, email address, topic, product, fleet size, region, budget, timeline, target date and message, plus the language of the page and the page you sent it from. The form is not stored in a database. It is used only to answer your request.
To limit abuse, the server keeps your IP address in memory for about an hour, to count the requests sent from it.
Server logs
Like most web servers, ours keeps standard access logs: IP address, page requested and time.
What is stored in your browser
The site keeps a few settings in your browser’s local storage (localStorage, not cookies): your theme choice, your language and region choice, and your cookie choice. They stay on your device, and you can clear them in your browser settings.
The Google Ads tag
Every page loads Google’s advertising tag (gtag, account AW-18324553059). Loading it connects your browser to Google’s servers, which are outside China. The tag runs in Google Consent Mode: until you choose, everything is denied and the tag sends only signals that use no cookies. If you click “Allow”, Google may set advertising and measurement cookies, and information about your visit is sent to Google with them. If you click “Decline”, or make no choice, none of these cookies are set. Google’s own privacy policy is at policies.google.com/privacy.

You can ask to see, correct or delete the personal information we hold about you, and you can withdraw your consent at any time. Write to marketing@efy-tech.com: requests about personal information are handled there. To withdraw your consent to cookies, you can also use the link below.
