Privacy Policy

The short version: the tools run in your browser, and what you paste into them never leaves your device.

What is processed where

Every tool on this site is plain JavaScript executing on your own machine. When you paste HTML, a robots.txt file or page copy into a form, that text is read by your browser and never transmitted anywhere. There is no endpoint that receives it, and no record of it is kept.

Cookies and advertising

This site displays advertising served by Google AdSense. Google and its partners use cookies to serve ads based on a visitor's prior visits to this or other websites. Google's use of advertising cookies enables it and its partners to serve ads based on visits to this site and/or other sites on the internet.

You can opt out of personalised advertising by visiting Google Ads Settings. Visitors in the EEA, UK and Switzerland are shown a consent prompt before personalised advertising cookies are set.

Third parties

Third-party vendors, including Google, use cookies to serve ads based on prior visits. No advertising vendor receives the content you paste into a tool — advertising scripts and tool inputs are entirely separate, and the tool inputs never leave the browser.

Data we do hold

Nothing beyond ordinary web server logs that any static site produces. There is no account system, no analytics on tool input, and no email list.

Changes

If this policy changes, the revision date below changes with it. Questions about any of this can go to renhongtao2@gmail.com.
