Our Core Principles

These are the foundational values that guide the development of every application on the Puenbann Platform.

Radically Private

We believe your data is yours alone. Our tools run in your browser, so your information never touches our servers. This isn't a policy; it's our architecture.

Transparent by Default

No black boxes. From our open-source code to our live process logs, we show you exactly how our tools work. Trust is earned through clarity, not claims.

Frictionless Workflow

Every click, every interaction, and every microsecond is considered. We design for speed and intuition, creating a seamless extension of your own workflow.

Sustainable Craftsmanship

We build for the long term. By focusing on quality, maintainability, and a sustainable business model, we ensure our tools are reliable and here to stay.
