Hey, nostr:npub14slk4lshtylkrqg9z0dvng09gn58h88frvnax7uga3v0h25szj4qzjt5d6. Is there a greater than normal privacy/security risk when using proxy sites like www hide.me/proxy?

Say I wanted to check my Protonmail on a public computer, or at work. Is my password at any greater risk than usual when using that proxy site?
