Your API key never touches my servers — here's how

Fair question for any "AI tool": where do my text and my key actually go? With Prompt Enhancer there's no backend of mine in the loop. You bring your own Claude API key, it lives in your OS keychain, and your selected text goes straight from your machine to Anthropic. I never see either one. I keep going back and forth on whether to also offer a hosted version — so I'm curious: is bring-your-own-key a dealbreaker for you, or the whole reason you'd trust it?
