Privacy Policy

Data we may collect

Depending on how you use the product, Vocal Director may collect:

• Account information — email address, display name, Firebase user ID (UID), and login provider information.
• Voice recordings and uploads — audio you record or upload for voice checks and karaoke analysis.
• Analysis and practice information — acoustic analysis results, practice history, and saved records generated from your use of the app.
• Service operation information — error, security, usage-limit, and stability logs needed to operate the service.
• Payment & subscription status — if and when payments are enabled later. Vocal Director does not directly store full payment-card details.

How your data is used

• Account operation — to create accounts, sign users in and out, and recognize the same account across supported devices.
• Voice analysis and records — to process recordings, provide AI coaching and practice guidance, and sync records when that feature is used.
• Entitlements — to apply free-use limits and subscription access.
• Service operation — to maintain security and stability, diagnose errors, provide support, and comply with legal obligations.

Keeping and removing data

Recordings and analysis results are stored by default in the local archive on the device you are using. Free users can keep up to three recent free-singing recordings on that device and can clear local audio from the app settings. Existing local records are not automatically merged into a signed-in account unless the app provides and you use an explicit import or sync action.

When you use Karaoke Voice Analysis, the uploaded original recording, separated vocal file, processing status, and analysis result are stored on the analysis server for up to seven days so that processing can finish and the result can be reopened. You may delete the server job and its files earlier from the result screen. They are automatically removed after the retention period. Real-time voice-check frames are processed for analysis and are not kept as permanent server recordings.

Local recordings can be removed through the app's record and settings controls or by clearing the app's device data. Signed-in users can request deletion of the connected account and its server-synced recordings, sessions, analysis data, and analysis jobs. We remove that data from active systems through the account deletion process, except where limited retention is required for security, fraud prevention, or legal obligations.

Our retention approach may evolve as the product matures. We will keep this policy updated to reflect meaningful changes to how long data is stored.

Services we may rely on

To operate Vocal Director, we use Google Firebase Authentication for account sign-in and may use Microsoft Azure for backend processing, storage, and AI services. App stores and future payment providers may also process data needed to provide their services. Each provider processes data only as needed for its role.

If you choose Google sign-in, Google's account and privacy policies also apply.

Consent & control

Except for the temporary seven-day Karaoke Voice Analysis processing described above, long-term server storage of original audio for later review occurs only when you have explicitly opted in. You can delete local recordings on your device, delete a karaoke analysis job and its original and separated files before expiry, and request access to or deletion of server-synced recordings and analysis data.

The app provides signed-in users with data export and account deletion under Account & data. You can also start a deletion request without reinstalling the app through the public Account deletion request page.

What Vocal Director is — and isn't

Vocal Director provides AI vocal coaching and acoustic guidance to support singing practice. It is not a medical device, and its acoustic metrics are coaching-oriented estimates, not a medical diagnosis.
