Principles

An arch stands on five stones.

The stone in the middle, the keystone, holds the others in place. For us that stone is respect for the people who use what we make.

  1. Calm

    No noise and no dark patterns. The interface stays out of the way.

  2. Exact

    Real numbers and checked details. Nothing left approximate.

  3. Keystone

    Respect

    No ads, no tracking, no data sold. The person using the software comes first.

  4. Durable

    Plain, maintainable code that keeps working for years.

  5. Direct

    A small team. You talk to the people who build it.
