tianli.cyou is the personal website of Tianli Zeng. This page explains what data is collected when you visit, how it is used, and the choices you have.
What is collected
- Analytics: this site uses Google Analytics (GA4) to understand page views and traffic sources. GA may use cookies and browser identifiers to process page paths, interactions, coarse location and browser information. This is not guaranteed to be fully anonymous. I do not intentionally link analytics identifiers with identities submitted through the contact form.
- Server logs: hosting services record request times, addresses, paths, referrers and browser information for operation and troubleshooting. The private dashboard summarizes 30 days of existing requests to articles, projects and selected product sites, including downloads. Summaries do not expose IP addresses, full referrer paths or personal identifiers, and do not build cross-session visitor profiles. Raw logs follow the server's rotation settings.
- Advertising: this site may show ads via Google AdSense. Google and its partners may use cookies to serve personalised ads based on your visits to this and other sites. You can opt out of personalised advertising in Google Ads Settings or learn more at aboutads.info. Advertising availability and privacy choices depend on the settings actually shown on the page.
- Contact form: the name, email and message you submit via the contact page are sent to the site owner through the email service Resend to respond to your request. The endpoint also uses IP addresses for short-term abuse prevention. Please do not include passwords or unnecessary sensitive information.
What this site does not do
- No visitor data is ever sold;
- These request summaries are not used to identify individual product users;
- Public content requires no registration. Preference and protected-page login features may use necessary cookies;
- The contact form does not collect payment information.
Your choices
You can block or clear cookies in your browser, opt out of analytics with the Google Analytics Opt-out add-on, and manage ad personalisation in Google Ads Settings.
