Free invoice generator, 100% client-side — no signup, no server storage

Made this: InvoiceCraft — a free online invoice generator.

A few things worth noting:

No account, no signup — just open it and start making invoices.
Nothing touches a server. Per their own privacy notice, all your data (company info, customer profiles, products, invoices) is stored entirely in your browser's localStorage. Nothing gets uploaded anywhere.
Free, with support for saved company profiles, saved customers, a products/services catalog, CSV import for products, and PDF export.
Since everything's local, clearing your browser data wipes it — so export/backup anything important.

Figured this might be useful for freelancers or small shop owners who don't want to hand invoicing data to yet another SaaS with an account and a database behind it.
