Privacy Policy

Last updated: October 26, 2026

This policy explains how the acumensync website (www.acumensync.com) handles information. The site is operated by 知悠网络科技（上海）有限公司 (Zhiyou Network Technology (Shanghai) Co., Ltd.).

What we collect

The site has no user accounts and no forms, and it does not use advertising or tracking cookies. We do not ask you to enter personal information on this site.

Preferences stored in your browser

To remember your language and light or dark appearance, the site saves these preferences in your browser's local storage. They stay on your device, are never sent to us, and can be cleared at any time in your browser settings. On phones and tablets, the illustration on the home page sways slightly as you tilt the device; the motion-sensor data is processed on your device in real time and is never stored or sent to us.

Online consultation

Consultations take place through WeCom (企业微信) customer service, provided by Tencent, or through WhatsApp, provided by Meta. Information you share in a conversation is handled under the respective provider's privacy policy, and we use it only to reply to you and discuss your project.

Server and network logs

Like most websites, our cloud storage and content delivery network (CDN) providers automatically keep basic access logs, such as IP address, time of visit and browser type, used only for security and operations. On your first visit, the site suggests a default language version based on your browser's time zone and language settings; this happens entirely in your browser and is not sent to us.

Changes and contact

If we add analytics or other features that handle personal information, we will update this policy first. For questions about this policy, email support@acumensync.com or contact us through the online consultation on the home page.
