Independent software that respects the people who use it.

I build tools that work offline, don't track anyone, and are paid for once. A knitting counter that doesn't need your location to count stitches. A timezone extension that converts times without phoning home. Writing about why the default state of software is hostile and what to do about it.

Principles

Offline first. Your data belongs on your device. Our apps run locally and only reach the network to verify purchases through standard platform infrastructure.

No subscriptions. Pay once and own it. Software you've bought should keep working without a monthly fee attached to it.

No tracking. No custom analytics, no third-party telemetry SDKs, no ad networks. We only see the baseline, anonymized metrics platforms collect by default.

Small and sharp. One thing, done properly. Every feature has to justify its presence, and most don't.
