Track where you go, keep it private, and let your AI assistant make it useful. Every request is logged, every token is revocable, and your data is never sold or shared. Fletcher is a privacy-first location tracker built for the AI era: it records your movement history, keeps it under your control, and lets your AI assistant answer questions about where you've been — with every access logged in plain sight. TRACK QUIETLY • Battery-friendly background tracking using significant location changes and visit detection • A clear Tracking toggle — when it's off, it's off, with an unmistakably grayed-out map • Live map that follows you, with manual zoom controls YOUR DATA, UNDER YOUR CONTROL • History lives on your device and syncs to the Fletcher sync server — or run the open Fletcher server yourself and point the app at it in Settings • No account, no email, no name: registration is an anonymous device ID • Retention you choose, from 7 days to forever — enforced locally and on the server • Delete a single point, or wipe everything locally and remotely, anytime CONNECT YOUR AI ASSISTANT (MCP) • Fletcher includes a Model Context Protocol (MCP) server — the open standard supported by Claude and other AI assistants • Generate a connection token in the app, paste it into your assistant, and ask things like "Where was I last Tuesday afternoon?" or "How often did I visit the gym this month?" • Precision control: share exact, ~100 m, or ~1 km coordinates with assistants • Revoke a token at any time — revocation takes effect immediately, even mid-session TRANSPARENCY, BUILT IN • Every assistant request is logged: what was asked, when, and how many locations were returned • Review the full request history right in the app • No analytics, no ads, no third-party SDKs EXPLORE YOUR HISTORY • Interactive history map with start and end markers, smooth even with thousands of points • Fast list view with swipe-to-delete • Sync status view with diagnostics and manual controls Fletcher is for people who want the convenience of a location-aware AI assistant without handing their movement history to a data broker. Your location data is used for one thing — your own history — and is never sold, shared, or used for advertising.
