Is your software paid?

What is free and what is paid is marked per product on the matrix site. This site lists no prices and takes no payments — orders and invoices are all handled there.

Can you build an internal tool for our company?

Yes. Websites, desktop software and mini programs can all be custom built. From sorting out the requirements to launch we do it ourselves, with no subcontracting; scope and schedule are confirmed by mail or in person, and this site carries no default promise.

Something broke, or I have a suggestion — how do I reach you?

Email rd@qthy.cc with the product name, version and steps to reproduce; we can usually locate the issue directly. For security matters put "security" in the subject line and we take it first.

Where do I download your products, and how do they update?

Everything is downloaded from the product matrix site. Installers carry a version number and release notes; background updates are supported, and a bad release can step back to the previous version.

My account or order has a problem — who do I ask?

The product matrix site handles all of it, with tickets and order context on hand — sending the order number makes it fastest. This site takes no payments and stores none of your account data.

What does a custom project look like, step by step?

You describe the thing you want solved in one email; we come back with a workable plan and its scope. Once confirmed we start, and we carry it from requirements to launch ourselves — if a step cannot hold, we say so before moving on.

How do you keep software quality up?

Release notes state what changed in every update; light and dark modes plus full keyboard access are defaults, not patches; every release is checked against the same standard, and a bad release can step back to the previous version.

Do you take small projects too?

Yes. Fit comes first: we look at the setting and the form, give you a scope and schedule when we can do it well, and say so plainly when we cannot.

Useful.Playful.Effortless. - HaoYou TechnologyOfficial site

We develop our own software for everyday users: website platforms, PC desktop software, mini programs and mini games.

A technology company that writes the code and builds the interface. The form, the interface, the servers and the release process are all in our own hands, so every item has to work as soon as it is installed.

Your reason

I am here to use the softwareDownloads, activation, orders and accounts all live on the product matrix site. One account covers every product.
I am here to discuss workChannel distribution, custom software for a business, media content. We start by getting the scope clear.

These numbers are derived live from the data on this site. They do not cover every product the company has. Product and launch status follows the matrix site on the day you read it.

Three claims, built into the products

"Useful. Playful. Effortless." is not a slogan. Each claim maps to a standard we actually apply when building.

Useful

Everything starts by solving one real problem.

Compressing files, finding files, checking answers, building guides. The test for a feature is whether you would open it again next week.

See what we build

Playful

"HaoYou" is a standard, not decoration.

Does a button answer when you press it? Do you know the progress while something loads? Does an empty screen invite you to do something? These parts do not change the function, and we hold them to the standard we would use for a game.

See how we work

Effortless

It works right after install. Nobody has to read a manual.

Defaults are chosen for you, and the first screen already has something to do. Where an explanation is needed, we write it into the interface instead of a separate document.

Mainstream products, every scenario covered

Websites, desktop software, apps, mini programs, mini games — the mainstream forms are all developed in-house, from idea to launch, with no outsourcing.

Websites and online platforms

Things that work right in the browser: official sites, tool collections, online platforms shared by many people.

Built with search in mind: page content is fully readable by search engines
Content updates on its own, without waiting on a development slot
Light and dark modes plus full keyboard access are defaults, not patches

Desktop and local software

When it needs local files, offline work or a long stay on the machine, it becomes software that works right after install.

Compression, tidying and checksums for large batches of files
Background updates, and a bad release can step back to the previous version
A portable first approach: dependencies are not pushed into your system folders

Accounts and supporting services

Every product shares one account: register once, use it everywhere.

Ordering, payment, activation and entitlements all happen online
One account works across the website, the software and the mini programs
User data serves the product function itself and is not collected beyond that

Mini programs and mini games

Finish a task or play a round inside WeChat, without installing anything.

Ordering, content browsing and account links inside mini programs
Tap-to-play mini games with light save state
The same account as the website and the desktop software

One job, seven ways to build it

We pick the form that fits the scenario best on cost and experience. The table below sets out how we choose, and what each form delivers.

How to choose among the seven product forms, and what each one delivers
Form	When to choose it	What you get
Website platformOpen a browser and use it. Nothing to install first.	Content changes often, several people share it, and it has to show up in search results.	A site you can visit: content fully readable by search engines, light and dark modes, content managed in an admin and tied to the same account system.
PC softwareRuns on your machine. Faster and steadier with large files and with no network.	It needs the local file system, batch work, or it has to keep running offline.	An installer with a version number and change notes. Silent updates, and a rollback to the previous version.
Mobile appThe everyday entry point on your phone, sharing one account with the desktop.	The task has to be finished on a phone and still connect to the desktop client.	A mobile client on the same unified account and message channel.
Mini programUse it and leave. It takes no storage on your device.	The need is light, and an install would put people off.	A mini program published in the WeChat ecosystem, with ordering, content and account links built in.
Mini gameOpens on tap. One round is about three minutes.	Entertainment in the gaps between things, with no download for it.	A mini game that starts on tap, with light save state and a leaderboard.
Open source projectThe holes we fell into, turned into shared components the community builds on too.	A general capability that grew out of internal tools and is worth testing outside.	Public repositories and reusable components. Issues and pull requests are open.
Browser extensionPut the actions you use most inside the window you already have open.	The same action is repeated in the browser every day.	An extension package and a permission note. We ask for the least permission that works.
