Privacy Statement
Last updated: July 20, 2026. JianFan.app is a browser-local Chinese Simplified and Traditional conversion tool.
Text you paste, and content extracted from TXT, DOCX, PDF, Excel, and similar files, is read and converted in your current browser. JianFan.app does not upload that text or those files to our servers for processing.
JianFan.app currently does not require accounts and does not actively collect your name, email address, conversion text, uploaded file content, or conversion results.
To remember the interface language and your custom dictionary, the site stores related settings and entries in your browser. Dictionary entries are not uploaded to our servers. You can remove them with the clear-dictionary control or by clearing browser site data.
To load the conversion engine and file parsing features, pages may request OpenCC and related browser scripts from a CDN. The CDN provider may process IP addresses, browser information, and request logs under its own policies.
Although conversion runs locally in the browser, you should evaluate your browser, device, and network environment before processing highly sensitive, regulated, or confidential text.
If site features, resource loading, or data handling changes, we will update this page and show the new update date above.
