The nsec is encrypted clientside.
But the best thing you can do is just self-host it!
Provider like nsecbunker? I haven’t check the code. Technically they know for a moment when you enter it, and then encrypted it with your “password” and then store it. nostr:npub1l2vyh47mk2p0qlsku7hg0vn29faehy9hy34ygaclpn66ukqp3afqutajft

The security model is very similar to Voltsge: isolated instances, secret is encrypted on disk and requires interactivity from the user to unlock when the server restarts.
But again, the magic with these things is that you can easily self-host them! 😉
