Hey everyone! Creator here 👋
A few things worth knowing:
- The entire tool is a single .html file — you can download it and use it 100% offline, forever
- The encryption happens in your browser — your seed phrase never touches any server
- The source code is public on GitHub (link in the description) — security researchers, please roast it 🔍
The metal engraving service is the only paid part ($59.99 for steel, $99.99 for titanium) — the software itself will always be free.
Happy to answer any questions about the crypto/security side of things!
