Philosophy

How we think about software

🔒

Your data is yours

It lives on your device. We never see it, store it, or sell it.

📖

Open by default

All our code is public. See for yourself.

🎨

Design matters

Beautiful interfaces aren't just for Big Tech.

🎯

Does one thing well

Each app has one job. It does it well.
