MAINS Lite has no server, no accounts, and no analytics. There is nothing for us to collect, because nothing you do in this app is ever sent to us.
Any API key you enter (OpenAI, Anthropic, Gemini, Groq) is saved only in your browser's localStorage, on your own device. It is never transmitted to any MAINS-controlled server.
When you send a message, it is sent directly from your device to the AI provider(s) you've configured, using your own API key. That request never passes through a MAINS server — this app has none. Each provider's handling of your data is governed by that provider's own privacy policy, not this one:
No accounts, no tracking scripts, no analytics, no cookies, no server-side logs of your keys or messages — because there is no server. This app is open source; you can read exactly what it does at github.com/crypto-chad111/mains-lite.
Clear your browser's site data for this app, or use the "Clear" and "Keys" controls in the app itself. Since everything lives only in your browser, deleting it there deletes it everywhere.
