I charge for a single-file web app I can't protect from piracy

The app is a local-first budgeting tool — one HTML file, no backend, no accounts, no tracking. That's the whole point. But it also means there's no server to check a license, no account to suspend, and no technical way to prevent copying. This is the story of choosing shareware-style trust-based monetization instead of DRM.

I can say I am pleased to see that!

I did something similar with it. It addresses the pain points of typical real estate owners (landlords and tenants). https://der-walter.de/

On Google, the game I made is more trending than the tools.

I think the monetization is still unresolved.

I did some experiments with the File System Access API. So users can select a folder, work in it via the web app, and just leave.
