Privacy Policy

This policy applies to the TwoThink brand portal and the tool sites operated by 双思睿（天津）科技有限公司 ("we", "us").

Browser tools: The tools on sites such as PDF and Video run locally in your browser. The files you select are not uploaded to our servers by default — both processing and downloading happen on your device. Where an individual site has additional notes (for example, loading a WASM module), the privacy page of that site takes precedence.

Desktop products: Desktop software such as 回单通 (Huidantong) and 翻图 FindAgain is designed around offline, local-first operation. The precise data paths and network behaviour of each product are set out in that product’s own documentation.

We may use anonymous traffic analytics tools, such as 百度统计 (Baidu Analytics), to understand how our pages are visited. These tools never read the contents of your files.

If you have a privacy question, please contact us at: hello@twothink.xyz
