How we train

House rules

Four rules, no exceptions. They're why every app on the card weighs what it does.

1

No dependencies

Every library is somebody else's supply chain. We compile against the operating system and nothing else — what you audit is what you run.

2

No network

If a tool doesn't need the internet, it doesn't get the internet. Nothing is sent anywhere, because nothing can be.

3

One file

No installer, no background services, no registry sprawl. Copy it to run it. Delete it and it's gone without a trace.

4

Fast is respect

We don't build in features nobody cares about. We build in speed. Cold start is measured in milliseconds — the best splash screen is none.

Zero third-party code

There is no supply chain.

Every app on this card ships without a single third-party dependency. No packages, no frameworks, nothing vendored in. We compile against the operating system, full stop. Nobody can poison a dependency we never took: there is no supply-chain vulnerability, because there is no supply chain.

Don't take our word for it. Run dumpbin /dependents on any Windows binary and the whole import list is Windows. Unzip an APK and there's nothing inside but our code.
