02 / Why Day21

Useful by design.
Respectful by default.

The same four principles, from the first install to the twenty-first day.

01 /

One job,
done well

Clear purpose. Useful defaults. No feature sprawl or settings maze between you and the thing you came to do.

02 /

Privacy-first
by default

Data minimization guides every product. Processing stays local wherever possible, with an explicit privacy policy for each tool.

03 /

On-demand
permissions

Access should follow intent. Grant what a feature needs when you choose to use it, with a clear reason before you decide.

04 /

Plain-language
legal & support

Know what a tool does and what it asks for. Readable policies, honest limits, and a real person when you need help.

03 / On the Workbench

Good things take a little work.

A look at what we’re making next. We’ll ship when it earns its place.
