Who we are
We are a small team of engineers in Beijing. DeskFox.Ai is our product brand; the company behind it is Lengjie (Beijing) Technology Co., Ltd., founded in 2026. We build software we want to use ourselves, and our goal is simple: use technology to make everyday life a little better.
How we build
Each of our apps does one job and does it properly: an assistant for the work on your desk, a teleprompter for talking to the camera, a place for the health data your phone already collects. No bloat, no feature lists for their own sake. If a feature does not serve the one job, it does not go in.
How we handle your data
We care about who holds your data. Our apps are built to collect as little as possible: no accounts of our own, and your files stay on your devices.
The one exception is AI features that run on third-party models. For those, we only work with providers whose terms rule out training on your data, and we never opt in. When you bring your own model or AI client, that provider's terms apply. Every product page says exactly what is sent, where, and how to switch it off.
Talk to us
