Privacy Policy

Effective: January 1, 2026 · Last updated: January 1, 2026

1. What We Collect

This app does not collect any personally identifiable information, including but not limited to name, email, phone number, location, contacts, or photos.

There is no account system. All features are available without registration.

2. Microphone Access

This app may request microphone access to detect pitch in real time (tuner) or record audio (recorder tools).

• Audio is processed locally on your device in real time
• It is never saved to a server
• It is never shared with any third party
• It is discarded immediately after processing

You can revoke microphone access anytime in iOS Settings → Privacy & Security → Microphone. Doing so only affects related features.

3. Network & Data Upload

This app does not request network access, or only accesses the network in rare cases (such as checking for updates), and never transmits personal data.

This app contains no ad SDKs, analytics SDKs, crash reporting SDKs, or any third-party tracking components.

4. Data Storage

Content you create in the app (such as recordings or preferences) is stored only in your device's local sandbox.

• Uninstalling the app deletes this data
• We cannot access your local data
• You can back it up via iOS system backup

5. Third-Party Services

This app integrates no third-party advertising, analytics, or social services.

6. Children's Privacy

This app collects no user data, so it is suitable for all ages, including children.

7. Your Rights

Since we do not collect your data, there is no need for data export, deletion, or correction. You have full control over all data on your device.

8. Policy Changes

If this policy changes materially, we will update it in the app or on this page, and revise the "Last updated" date.
