Why nothing is uploaded
Every operation on this page is done by code running inside your browser tab, using the same engine that renders web pages. The file is read from disk into your tab’s memory, transformed there, and written back out as a download. It is never sent anywhere — not to us, not to a third party.
Verify it yourself
- Open your browser’s developer tools (F12) and select the Network tab.
- Load your file and run the tool.
- The only requests you will see fetch the tool’s own code — and, for a few heavy tools, their open-source engine from a public CDN — plus one small page-view ping to loreatec.jp (page address and title, nothing more). None of them carry your file.
Frequently asked questions
Does Shanghai change its clocks for daylight saving?
This converter always uses Shanghai’s official rule for the date you pick, so whether or not it observes daylight saving, the time shown is correct for that day. Move the date across a clock change and the offset follows.
Is anything sent to a server?
No. The time is computed inside your browser from the time-zone data it already carries. Nothing about your query leaves the device, and the page keeps working offline.
