Software that behaves like a tool, not a tenancy.

OwnDesk is a small independent shop. I build finished business applications and sell them outright: one file, one payment, yours to keep.

It started with a workshop that was running on a whiteboard and three spreadsheets. The commercial options cost more per month than the shop spent on coffee, needed a login, and stopped working the day the internet did. So I built the thing that should have existed: everything the shop needed, in one HTML file, opened by the browser already on the counter.

Three rules I do not break

Your data does not leave your computer

There is no server to send it to. That is not a privacy policy, it is an architecture — I could not read your records if I wanted to.

You pay once

No seats, no renewals, no tier that quietly loses the feature you bought it for. The price on the product page is the whole price.

I tell you what it cannot do

Offline single-file software cannot sync between users, send SMS, or take card payments inside the app. That is written on the product pages, not buried in a support article after you have paid.

How it is built

Every product shares one storage engine: records live in the browser database, and each change is written first as a line in a journal so a crash mid-save loses nothing. The same engine means the same reports, the same exports and the same keyboard habits across the range — and it means a fix in one product reaches all of them.

Several products also ship as a macro-free spreadsheet edition, so they open in Excel, LibreOffice and Google Sheets without asking anyone to trust a macro.
