Privacy Policy
This page explains what stays in your browser when you visit QR9.NET and use its tools, and what may be recorded by the hosting environment or third-party analytics.
Tool input
The tools currently provided by QR9.NET run in the browser. Text, files, keys, images, or other content you process are not uploaded to QR9.NET servers as tool computation input.
If a page needs to load model files, scripts, styles, or images, the browser still sends network requests for those resources. Those requests do not need to submit your tool input as the request body.
Shared computers, unknown browser extensions, the system clipboard, and device security can still affect the risk of handling sensitive information.
Browser storage
Some tools store interface state, temporary results, or local history in your browser, such as JSON tool history or metronome settings.
You can clear site data, cache, and local storage from your browser settings.
Logs and analytics
- Hosting services, CDNs, or web servers may record basic operational logs such as time, IP address, User-Agent, request URL, and error status.
- In production, this site may load the Baidu Analytics script after user interaction or after the page has been open for a while.
- Analytics are used to understand page visit trends. This site does not use analytics to read local content in tool inputs, file selectors, or key fields.
