Octoweb is a local application. It has no backend, no account system, and no analytics. This page describes what it stores and the one case where data leaves your Mac.

What stays on your machine

  • Browsing history and sessions — kept in ~/Library/Application Support/octoweb/, capped by max_history in your config.
  • Workspace data stores — cookies, localStorage, and cache live in a separate WebKit data store per workspace and are never shared between them.
  • Favicons — cached as base64 data URIs, so startup makes no network calls.
  • Prompt history — sidebar and inline-edit prompts are stored in ai_prompt_history.json, capped by your config.
  • Keybindings and settings — plain files under ~/.config/octoweb/ and the application support directory. Delete them and the app returns to defaults.

What the browser sends

Page requests go to the sites you visit, exactly as any browser does. Beyond that, Octoweb itself sends nothing: there is no telemetry, no crash reporting, no update ping, and no usage analytics.

AI features

The AI sidebar, inline edit (⌘⇧E), and proactive learning connect over ACP to an octomind agent running on your own machine. That agent — not the browser — calls whichever model provider you configured, using your API key. If you never start octomind, nothing AI-related runs at all.

Proactive learning is enabled by default. Every 30 minutes it passes your open tabs, recent history, and the active page's text to the local learning agent, which stores insights in octomind's local memory. Turn it off in Settings (⌘,) or set proactive_learning = false in your config.

The MCP server

Octoweb listens on localhost:3434/mcp so local MCP clients can drive the browser. It binds to loopback only. Any client that can reach it can read page content and history, so treat it like any other local development port.

This website

octoweb.xyz is a static site with no analytics, no cookies, and no third-party scripts. The host records standard server logs; we do not build profiles from them.

Verifying all of this

Octoweb is Apache 2.0-licensed. Everything above is checkable in the source, which is the point of shipping it open.
