Tiff Zhang Labs ("we" / "us") is the collection of web apps at labs.tiffzhang.com and related paths. These apps are static: we do not run our own application servers or databases that store your usage or content for the site as a whole. We use Google Analytics (GA4) to track usage data only if you accept it in the cookie banner.
GA4 may set cookies or use similar storage if you opted in. You can change your mind anytime via the banner (after clearing the saved choice), your browser's site data controls, or Google's own tools and policies.
We do not sell personal information. Sharing is limited to the services above (analytics and hosting, and providers you connect yourself).
Analytics retention follows Google's settings and policies. Data kept only on your device is under your control.
The site is served from the United States. Using it may involve processing in the U.S. or other regions where Google or our host operates.
Use Accept or Reject on the banner for analytics, clear site data to reset the banner, or use your browser's privacy settings. For data held by Google or Spotify, use their account and privacy tools.
California residents: we do not sell personal information as that term is commonly used under the California Consumer Privacy Act.
These tools are not aimed at children under 13, and we do not knowingly collect information from children for our own analytics or accounts. Optional GA4 does not load until an explicit choice on the banner.
We may update this page and change the effective date above when we do.
