What FocusSwitch collects

Nothing. FocusSwitch does not collect, transmit, or store any personal data on external servers. There is no account, no telemetry, no analytics.

Data stored locally

• Bluetooth device metadata — names and MAC addresses of your paired peripherals, stored only on your Mac.
• Encryption keys — a Curve25519 key pair for secure peer communication, stored in a 0600 file inside your Application Support directory.
• Peer trust data — public keys of Macs you've paired with, stored in UserDefaults.
• Preferences and rules — settings, hotkeys, profiles, and automation rules, stored in UserDefaults.

Network communication

FocusSwitch communicates only between your own Macs, using:

• Bonjour / mDNS on the local network for automatic discovery.
• Bluetooth LE for proximity detection and zero-config cross-VLAN handoff.
• Direct TCP to peers you add manually by hostname or IP.
• ChaChaPoly encryption with Curve25519 key exchange for every message on every transport.

No FocusSwitch traffic leaves your home network.

Third parties

• Sparkle fetches appcast.xml from focus-switch.com to check for updates. We keep standard web-server logs (IP, user-agent) for abuse prevention and rotate them after 30 days.
• Apple App Store / StoreKit handles purchase and subscription logic. Apple's privacy policy applies to payment information.
