Data and privacy
ChroMind has no server. Here's exactly what goes where.
#What leaves your browser
Only when you send a message or run an action, and only to the provider you picked:
| Provider | Receives | Goes to |
|---|---|---|
| Claude | Your message, page text, screenshots | claude.ai, under your account |
| Your server | The chat, page text, images | Your server (and whatever model it uses) |
| Claude Code, Cursor, OpenCode | The chat and page text | The Bridge on your computer, then Anthropic, Cursor or OpenCode through their apps |
| OpenRouter, Gemini, OpenAI, Groq | The chat, page text, images | That company's API, under your key |
| Local model | The chat, page text, images | The server you entered |
Page text is read when you ask, not in the background. The Page switch in the panel turns it off per chat.
#What stays in your browser
- Settings, including API keys, your server's password and the Bridge token:
storage.local, never synced. - Model lists, cached for six hours so the picker opens fast.
- Chat history:
storage.local, up to 300 chats. Turn it off or delete it in Settings → Data & privacy.
#What ChroMind never does
- No analytics, telemetry or ads. There's no ChroMind server to send anything to. The update check reads a small version file from this docs site (GitHub Pages) at most twice a day, and sends nothing.
- Answers can't load remote images or scripts: the Markdown renderer drops raw HTML and images, so a page can't sneak data out through an answer.
- The selection toolbar only reads what you select, and only when you click it.
- On this docs site, ChroMind marks the page with its version number so the install page can tell you whether you're up to date. That's all it shares, and only with this site.
