Company
Who we are
leston.com.cn is the official website of Leston Trading (Shanghai) Co., Ltd., a software company registered in Shanghai, China. We build focused, honest tools — starting with LesHub.
◐
Local-first by default
Files, credentials, and personal data stay on your device. We do not build advertising SDKs into our products, and we do not run third-party trackers on our websites.
◑
Honest about status
We label what is shipped, what is in development, and what is only planned. If a feature is not available yet, our pages say so rather than implying it works.

Products
What we build
Our product work spans media and language tools. Both start from the same principle: your files and data stay on your machine unless there is a good reason for them not to.
▶
LesHub — Private media library
Turns local folders, NAS shares, and cloud drives into one poster wall. Recognises titles, seasons, and episodes from filenames, fills in real metadata, and plays your files with a genuine video engine. macOS and iPhone.
文
Leston Translate — Live translation and subtitles
Press and hold to speak, release, and get a translated transcript. On the desktop it captures system audio and renders live subtitles over whatever you are watching. Works with 15+ languages.

Before you write to us.
When will LesHub be available?
LesHub is launching soon. The first release is planned for macOS and iPhone on the App Store. Planned Pro pricing is US$8/month or US$88/year; see the product page for trial terms. This site does not distribute builds or beta invites — see the LesHub page for the current status.
Does Leston sell content or subscriptions to media?
No. Our products are software. LesHub plays files you already own or are authorised to access; it does not include or stream a content catalogue.
Do you collect my data?
Our websites use no advertising cookies and no third-party analytics. Our apps keep credentials and file paths in the device keychain. Details are in the LesHub privacy policy.
Where are you based, and in which language do you work?
We are based in Shanghai, China. Our products ship with English and Chinese interfaces, and support is handled in both languages.
