1. Introduction
This policy explains how Shamisen Tuner handles microphone access, local settings, and analytics.
2. Microphone Access
The app requests microphone permission only when you start the needle tuner. Incoming audio is analysed in the browser for pitch detection and is not sent to the server.
3. Local Storage
The app stores selected pitch presets, tuning patterns, A4 reference, volume, and metronome BPM in browser local storage so they can be restored on your next visit. These settings stay on your device.
4. Access Logs and Analytics
The server may keep standard access logs such as IP address, request time, and URL for operational purposes. The site also uses Google Analytics for anonymous usage statistics.
5. Third-Party Services
Google Analytics (Google LLC) may use cookies or similar technologies. SeeGoogle's Privacy Policyfor details.
6. Policy Changes
This policy may be updated when the app changes. Updates become effective when posted on this page.
