Who we are
Jingrui Yuetao is a small, deliberately senior team of designers, engineers, and product people who believe the web and mobile ecosystems deserve a different kind of company. Here is what we believe, how we work, and the journey that brought us here.
Our mission
Jingrui Yuetao exists to prove that a technology company can grow profitably while keeping its users’ data on the user’s device, charging a fair price, and never compromising the things that make software delightful: speed, beauty, and trust.
We treat privacy not as a compliance checkbox but as a design constraint that makes our products better. We treat localisation not as a translation exercise but as a cultural practice. We treat our users not as data sources but as guests we want to welcome back tomorrow.
Operating principles
If a feature cannot be built without sending user data to a server, we either redesign the feature or we don’t ship it. There is no third option.
No push notifications begging for attention, no red badge counts, no engagement loops. We respect your time and your attention span.
An app that needs the internet to open is not a finished app. Connectivity is a feature, not a dependency.
Right-to-left layouts, plural rules, time zones, currencies, calendars and cultural references are designed in, not bolted on.
Ads are clearly marked, never deceptive. Subscriptions cancel in two taps. We sell features, not your data.
We release small, often, and measure carefully. We treat every release as a learning and every rollback as a feature.
Our journey
Jingrui Yuetao was incorporated in Beijing with a simple thesis: most mobile applications are needlessly chatty, slow, and invasive. The founders started building offline-first utilities for their own use.
Our first product, an offline route parser for outdoor enthusiasts, launches to a niche but devoted audience. The decision to charge a small one-time price, instead of running ads, immediately wins the studio a loyal following.
Two more apps ship: a collection cataloguing tool for serious hobbyists, and a writing inspiration engine. All three apps share the same offline-first, no-account-required design DNA.
Localisation into twelve languages, plus a small but excellent paid user acquisition playbook, takes the suite to over a million installs across more than 80 countries.
The studio publishes a public write-up of its zero-data architecture pattern. Several peer studios adopt variations of the pattern. Ad mediation partners are brought in for the first time, with strict user-consent and frequency-cap rules.
The portfolio expands into sports training load and household bill scanning. Both apps use on-device machine learning for fully offline inference.
The studio formalises its data protection impact assessment process and partners with external counsel in the EU, US, Brazil and China. The trust centre on this site goes live.
The team continues to ship from Beijing, working remotely with collaborators across Europe, North America, Southeast Asia and the Middle East. Cadence, our periodic habit tracker, ships to record first-week installs.
