Privacy Policy — Otoyoi (おとよい)

Last updated: July 13, 2026

Otoyoi ("the App") is an iOS application developed and provided by Mahiro Works. The App is designed to respect your privacy completely: it collects no personal information and no usage data whatsoever.

Information We Collect

None. The App does not:

• Collect personal information (name, email address, location, etc.)
• Analyze usage (no analytics SDKs are embedded)
• Show ads or use advertising identifiers
• Require accounts or sign-in
• Automatically send crash reports or diagnostics

Your Audio and Video Files

• Audio and video files you import into the App are processed and stored only on your device
• Your files and any information about them are never sent to the developer or any third-party server
• Exporting mixes and creating or sharing backups happen only through your explicit actions

Motion Data (Head Tracking)

When head tracking is enabled with supported earphones, head-orientation data is used solely to compute sound positioning. This data is never stored or transmitted, and no access occurs when the feature is turned off.

Purchases

Purchases of the App are processed by Apple through the App Store. The developer does not receive any personal information about purchasers. See Apple's Privacy Policy for how Apple handles your data.

Children's Privacy

Since the App collects no data at all, no personal information is collected from users of any age.

Changes to This Policy

Any changes to this policy will be announced on this page. We currently have no plans to add features that involve data collection.
