About
The company is registered in Shanghai. Douhouse is the brand it publishes under.
What the company does
Two things, and they feed each other. We publish our own iOS apps, which is where the methods come from, and we take on client work in the same disciplines: software, AI applications, digital content and advertising.
Why the apps matter to the client work
Every app listed on this site went through App Review, store listing, in-app purchases and privacy declarations. That route is not theory here — it has been walked end to end, repeatedly, and it is the reason a schedule from us tends to survive contact with Apple.
What we will not do
We do not put an advertising or attribution SDK into a product to make a number look better, and we do not ship a claim that has not been measured. If something cannot be done in the time available, that is said before the work starts rather than after.
How we build
Offline first
Data belongs on the device wherever the product allows it. Anything that syncs says so plainly, in the product and in its policy.
No account to start
A product should be usable before it asks who you are. Sign-in is added where it earns its place, not by default.
Nothing sold about you
No advertising SDK, no attribution SDK, no selling of personal information — in any product we publish.
One thing each
Rather than one product that does everything badly, a small one per problem, each explaining exactly what it does.
The registered entity
Douhouse is the brand name. The company registered behind it is below, copied from the business licence, so it can be checked against the public registry rather than taken on trust.
