Koetoji Privacy Policy

Last updated: October 28, 2026

STUDIO-GENNAI explains below how Koetoji handles information. This is a separate app from the original Mute Pad; the original app's policy does not apply to this app.

1. Recordings and text on your device

Recordings, transcripts, titles, tags and notes are processed in app storage and are not automatically sent to an operator server. The recording library is encrypted at rest. No app account is required. The app includes no advertising, behavioral analytics or crash-reporting SDKs. Its features do not use your location, contacts or advertising identifier.

2. Transcription and permissions

The microphone is used for a recording you start. Live transcription uses OS-provided on-device speech recognition with no fallback to cloud recognition. Availability depends on the device, OS, recognition service, language and installed models. Preparing language models through the OS or recognition service may require a connection.

On Android, an ongoing recording notification and microphone foreground service allow a recording you started to continue while using another screen or with the screen off. If you enable the library lock, the app uses OS biometric or device authentication. The app receives an authentication result, but neither the app nor the operator obtains your fingerprint, face or other biometric data.

3. Retention, deletion and backup

Local records remain until you delete them or they are lost through clearing app data, uninstalling or other device events. The library and keys are designed to be excluded from OS cloud backup and device transfer. There is no library synchronization, migration or operator-run recovery feature. The operator cannot recover records made inaccessible by device loss or failure, or loss of records or encryption keys. Explicitly export important content if you need a separate copy. Encryption does not guarantee protection against every risk, including device compromise or accidental actions.

4. Sharing you choose

The app passes selected audio or text to another app only after you select items and use OS sharing. Export files are outside the encrypted library. A cloud or AI destination may transmit the content to that service, whose terms and policy apply.

Temporary export files are removed during subsequent cleanup, such as app startup or preparation of another share, after they are at least 24 hours old. Deletion is not scheduled for the exact 24-hour mark. The app cannot delete copies already saved by another app or service.

5. Purchases, restoration and OS services

Pro purchases, ownership checks and restoration use the App Store or Google Play and may require a connection. Store-provided product IDs, transaction IDs and purchase status are processed locally to verify access. Recordings and transcripts are not sent to an operator-run purchase-verification server. The app does not receive payment-card numbers. Store account and payment data and OS-standard diagnostics enabled through your settings are handled under the relevant provider's terms and policy.

6. Information you send to support

If you email us, we receive your address, message and any attachments you choose to send. They are used to reply, investigate problems, assist with purchases and restoration, and handle related disputes or legal requirements. A recording or transcript is not required. Do not send passwords, authentication codes, card numbers or unnecessary sensitive information. Without relevant information, we may be unable to answer or investigate a purchase; sending an email is not a condition of normal app use.

We use Gmail to receive and store email. Google processes it under that service's terms and may handle it outside Japan. See Google's Privacy Policy. Support records are deleted when they are no longer needed for the request, dispute resolution or legal obligations. They are not sold or used for advertising. Except where legally required or otherwise permitted by applicable law, they are not disclosed beyond providers necessary for those purposes.

7. Rights and requests

Contact us below for access, correction, deletion, restriction or other privacy requests. We respond under applicable law and may request proportionate identity verification. We cannot access or delete the library held only on your device; delete local records in the app.

Where applicable, including under EEA or UK law, rights may include access, correction, erasure, restriction, objection, portability and complaints to a supervisory authority. Contract-related support is processed to perform the contract; other routine investigation and replies rely on our legitimate interests in responding to users and resolving service issues; legally required retention relies on legal obligations. We do not make decisions based solely on automated processing that have legal or similarly significant effects.

8. This website

Visiting studio-gennai.com, including this page, may involve technical hosting data and website analytics depending on region and choices. See the website privacy policy (Japanese) for details and controls. Website processing does not add an analytics SDK to the app.

9. Changes and contact

We update this page and its date when practices change and communicate material changes through the app, store or another appropriate channel.
