tinglilab.com · privacy statement · version 1 · October 2026

This site has no accounts, forms, cookies, analytics or third-party scripts.

Server logs. Like any website, its server keeps standard access logs: your IP address, your browser's type, the pages and files requested (with any ?from= tag a link carried), the time, and the site that linked you. We keep them for security and to count how many people visit, how many pages they read, from which countries, and which links and sites brought them. They are kept 15 days and not combined with anything else, and the daily counts we make from them keep no addresses and nothing else about you.

The from tag. If you arrive with a from tag in the address (such as ?from=org, from a link on the free tone lab), a small script keeps it in your browser's session storage and adds it to the links into the lab; if you arrive without one, it adds from=com. That is how the lab counts which links bring people to it, not which pages they read. The tag is never sent anywhere else, and it goes when you close the tab.

The lab, and the free tone lab. The full lab at mandarin.lexlovers.com has its own privacy statement, and so does the free tone lab at tinglilab.org:

• The lab's privacy statement (mandarin.lexlovers.com)
• The free tone lab's privacy statement (tinglilab.org)

Who runs it. tinglilab.com is made by Ranjan Chaudhuri in Canberra, Australia; in this statement “we” means Ranjan Chaudhuri. Questions: hello@tinglilab.com.
