04 · PRINCIPLES

What we believe

Good apps don’t need to be complicated, and shouldn’t trade your data for convenience.

Simple

Each screen does one thing, so no manual is needed.

Private

If data can stay on the device, it does.

Human in the loop

AI finds the information; people make the final call.

Built to last

Code and docs our future selves can understand.
