Leash is designed with privacy as a core principle. We do not collect, store, transmit, or share any personal data or usage information whatsoever.
Leash collects no data. The app operates entirely on your local device. No information is ever sent to external servers, third parties, or Thierry Frache.
Leash uses Bluetooth Low Energy (BLE) to detect the proximity of your paired devices. All Bluetooth scanning and signal processing occurs exclusively on your Mac. No Bluetooth data, device identifiers, or proximity information is transmitted outside your device.
Leash stores your preferences locally on your Mac using macOS standard UserDefaults. This data never leaves your device.
Leash contains no analytics, tracking, or telemetry of any kind.
Leash does not integrate with any third-party services, SDKs, or frameworks that collect data.
