Your blocklist, browsing history, app names, and settings never leave your Mac. There is no account, no login, and no server that stores your data.
Two things are sent off-device, and only these two:
1. Crash reports (always on): if the app crashes, a stack trace goes to Sentry (EU-hosted) so I can fix the bug. No personal data, no blocklist, no IP address.
2. Anonymous usage stats (opt-in, off by default): if you enable 'Help improve FocusDragon' in onboarding or Settings → Privacy, events like 'focus_session_started' are sent to PostHog (EU) so I can see which features actually get used. Toggle it off anytime.
See the full privacy policy for the exact list of events.
