Where is the company registered? None of these details are on your website.
It's a small solo project; there's no company entity yet, but also no account or server, so nothing of yours is collected — files are processed in your browser and never leave your device (verifiable in the Network tab).
Two things that don't depend on either: (1) the offline test is something anyone can do ,load the page, turn off your wifi, and the tools keep working, which they couldn't if they relied on a server; (2) the site ships a Content-Security-Policy that blocks outbound connections, so it's the browser enforcing it, not my word. The real fix for trust is open-sourcing it and getting a third-party audit, which is on my list.
Appreciate you pushing on this.
