Why I built it //

A photographer with a data habit.

Running a studio meant spreadsheets, paper agreements and notes in five different apps. After twenty-five years of working with data, I knew it could be one calm, private place — so I built it.

Private by design

your studio stays on your devices

Small conveniences, like the weather where you are, are opt-in.

Anywhere in the world

your country’s law, tax & year

Governing law and tax wording follow where you work. Overseas bookings keep the venue’s time zone.
