Why it's safe
The safety story reads like a spec, not a slogan.
Browser-only
Generation stays on your device, so the values never need to leave the page.
No upload
Nothing is sent to a server while you generate or copy secrets.
No storage
Reloading clears the result list, which keeps the workflow ephemeral.
