Overview
LochTone is a bagpipe tuner and metronome app for iPhone, iPad, and Apple Watch. Your privacy is important — LochTone is designed to work entirely on your device with no data collection.
Data We Collect
None. LochTone does not collect, store, transmit, or share any personal data.
- No user accounts or sign-in
- No analytics or usage tracking
- No advertising or ad identifiers
- No network requests of any kind
- No crash reporting to external services
Microphone Access
LochTone requests microphone access to detect the pitch of your instrument in real time. Microphone audio is:
- Processed entirely on your device
- Never recorded, stored, or transmitted
- Discarded immediately after pitch analysis
- Only accessed while the tuner is actively listening (indicated on screen)
You can revoke microphone permission at any time in Settings > LochTone.
On-Device Storage
LochTone saves your preferences (tuning presets, metronome settings, reference pitch) locally on your device using standard iOS storage (UserDefaults). This data:
- Never leaves your device
- Is not backed up to any external server
- Is included in standard iCloud/iTunes device backups only if you have device backup enabled
- Can be erased entirely using the Factory Reset option in the About screen
Apple Watch Companion
The WeeLinneNome Watch app communicates with the LochTone iPhone app over Apple's WatchConnectivity framework to relay metronome tempo, playback state, and haptic settings. This communication:
- Occurs only between your own paired iPhone and Apple Watch
- Uses Apple's encrypted device-to-device channel
- Contains no personal data — only metronome configuration (BPM, beat pattern, haptic preferences)
Preset Sharing
LochTone allows you to share tuning presets with other users via a URL link. Shared preset URLs contain only tuning parameters (frequency, temperament, threshold). No personal information is included in shared links.
Third-Party Services
LochTone uses no third-party SDKs, frameworks, libraries, or services. The app is built entirely with Apple's first-party frameworks.
Children's Privacy
LochTone does not collect any data from any user, including children. The app is suitable for all ages.
