Cookie Policy
Last updated: November 11, 2026
This Cookie Policy explains how Proabbio ("we", "us" or "our") uses cookies and similar technologies on www.proabbio.com and www.proabbio.cn (together, the "Sites"). It should be read together with our Privacy Policy.
1. What Are Cookies?
Cookies are small text files placed on your device when you visit a website. They allow the website to recognize your browser, remember your preferences, keep you signed in, and understand how the site is used. Similar technologies include local storage, pixels and web beacons. In this Policy, we refer to all of these as "cookies".
2. How We Use Cookies
- Strictly necessary cookies: required for the Sites to function, including session management, form submission, security and load balancing. These cookies cannot be disabled through our site without affecting core functionality.
- Preference cookies: remember choices such as display settings or previously entered form information, so you do not need to re-enter them.
- Analytics cookies: help us understand how visitors use the Sites so we can improve content and performance. We currently do not deploy third-party advertising or analytics cookies on the public pages of the Sites; if this changes, we will update this Policy and, where required, request your consent.
- Marketing cookies: used to measure advertising or deliver relevant content. We do not currently use marketing cookies.

4. Third-Party Cookies
We do not currently set third-party advertising cookies. Some third-party services linked from or embedded in the Sites, such as video players or social sharing tools, may set their own cookies when you interact with them. Those cookies are controlled by the relevant third party and are subject to its cookie and privacy policies.
5. Managing Cookies
Most browsers allow you to view, block or delete cookies through their settings. You can also configure your browser to notify you when a cookie is set. Please note that blocking strictly necessary cookies may prevent you from using forms, the member center or other parts of the Sites.

6. Do Not Track
Some browsers offer a "Do Not Track" signal. Because there is no common industry standard for interpreting these signals, the Sites do not currently respond to them. We do not track users across third-party websites for advertising purposes.
7. Changes to This Policy
We may update this Cookie Policy to reflect changes in the cookies we use or applicable law. The revised version will be posted on this page with an updated "Last updated" date. Where required, we will seek your consent before using new categories of cookies.
