What's tracked, what's not, where it lives, how to turn it off or clear it
Three things: when you open an opponent's profile, when you read a "Next time" note, and when you generate an AI brief. Each is stored as a typed event with a timestamp and opponent ID — never note content. It exists so the app can show whether reviewing before a match correlates with winning.
No tap heatmaps, no scroll tracking, no search queries, no third-party analytics SDKs — nothing about what you write. The telemetry is a short, fixed list of typed events, not a general analytics pipe.
It's your own data: it's saved to your storage (Google Drive / Dropbox / iCloud) and synced across your devices — never to our servers. Settings → Privacy → the Behavioral tracking toggle stops new capture on this device (and makes new matches read "unknown" instead of classifying them); "Delete behavioral history" wipes everything already recorded across your devices. Your opponent notes are never affected.
