This page describes document handling as implemented in the application. It does not add promises the code does not keep.
Uploads are stored temporarily
When you convert a document or a Pinyin file, the file is uploaded to the server and written to a temporary folder (tmp by default). The maximum upload size is 20 MB.
The server creates a converted output file in that same temporary area. Conversion runs on this server. The application does not send your document to a separate conversion vendor.
Downloads last 30 seconds
After conversion, the site returns a one-time download link. The converted file is available for 30 seconds. If you download it, the temporary input and output files are deleted. If you do not download it in time, the server deletes those files when the timer expires.
A periodic cleanup job also removes leftover temporary files.
What is logged
Server logs may include the original filename, the conversion type you chose, timing, and error messages. The application is not written to store the full document body in a content database.
What runs where
- Document conversion and text conversion run on the server using OpenCC.
- File and text Pinyin generation run on the server.
- The Pinyin Writer runs in your browser and does not upload a file.
Analytics and ads on the public website
The homepage may load Google Analytics and ad scripts. Those are separate from the conversion pipeline. They are not used to store your uploaded DOCX in a document archive, but they are third-party scripts on pages that include them.
