Design Philosophy
01
Built for myself first

Every tool here started as something I actually needed. If it solves my problem properly, chances are it solves yours too.

02
Try before you buy

Shareware. The original model. Download it, use it with real data, decide if it's worth the price. No time limit, no crippled features.

03
No nonsense

No accounts. No cloud sync. No subscriptions. No dark patterns. A file that does a job, runs in your browser, and gets out of the way.

About the Author
STEVE.BIO

MADE BY SOMEONE
WHO GETS IT

I spent decades in IT — the kind of career where you end up knowing how computers actually work, rather than just how to use them. These days I describe myself as independently operational: done with the 9-to-5, but nowhere near done with building things.

The software here is what happens when you have a real problem, the skills to solve it properly, and the stubbornness to actually finish it. The Etsy Tax Tracker started because I needed one myself — sitting there each April staring at CSV exports thinking there had to be a better way.

I make tools I use every day. That means they get properly tested, properly thought through, and properly updated when something changes. Not vaporware, not abandonware — software with someone behind it.

Got a question, a bug, or an idea? I actually read my email: software@lyonsden.net
