Privacy Policy

Resonance Lab: Binaural Studio ("Resonance Lab", "the app", "we", "us", or "our") is an Android audio creation and wellness tool that lets users play, customize, save, share, and export binaural and modulation audio sessions.

This Privacy Policy explains what information is handled by the app, what stays on your device, what may be processed by third-party services, and how to contact us.

1. Information Stored Locally on Your Device

The app may store the following information locally on your device:

• Saved audio session settings.
• Safety notice acknowledgement preference.
• Settings JSON files that you choose to export or import.
• WAV audio files that you choose to export.
• Local export license records, including export type, date, app version, settings hash, file name, render duration, and sample rate.

This locally stored information is not automatically uploaded by the app as audio files. You control if and where exported settings or WAV files are shared.

2. Purchases

The app uses Google Play Billing to process in-app purchases for Personal WAV Export and Commercial WAV Export licenses. Google Play processes payment information. We do not receive your full credit card number, bank account information, or other full payment credentials.

For purchase verification, the app and/or our licensing service may process purchase-related metadata such as:

• Product ID.
• Purchase token.
• Purchase state.
• Export license type.
• Settings hash.
• App version.
• Export timestamp.
• Basic request metadata such as IP address and user agent as part of normal server operation.

The app does not need to upload rendered WAV audio to verify a purchase.

3. Ads

The app uses Google AdMob to display ads. Google and its partners may collect and process information such as device identifiers, advertising identifiers, approximate location, ad interactions, diagnostics, and other data described by Google's advertising and privacy policies.

You can manage ad personalization and advertising ID settings through your Android device settings and Google account settings.

4. Licensing Service

The app may contact the Resonance Lab licensing API to verify purchases, record export license metadata, support purchase recovery, reduce abuse, and help with customer support.

The licensing service is not designed to receive rendered WAV audio files. It may receive purchase and export metadata necessary to verify and record export licenses.

5. How We Use Information

We use information handled by the app to:

• Provide playback, saving, importing, exporting, and sharing features.
• Process and verify paid export licenses.
• Maintain local export/license records.
• Display ads.
• Prevent fraud and abuse.
• Respond to user support requests.
• Improve reliability and release readiness.

6. Sharing

We may share or process information with service providers only as needed to operate the app:

• Google Play Billing for purchases.
• Google AdMob for ads.
• Cloudflare Workers/D1 or another backend provider for licensing records and verification.

We do not sell user-created WAV audio files or saved session settings.

7. Data Retention

Local saved sessions, settings, WAV files, and license records remain on your device until you delete them or uninstall the app.

Server-side purchase and export license metadata may be retained as needed for purchase verification, fraud prevention, customer support, legal compliance, and business records.

8. Your Choices

You can:

• Delete saved sessions inside the app.
• Delete exported files from your device storage.
• Clear app data or uninstall the app to remove locally stored app data.
• Manage ad personalization through Android and Google settings.
• Contact us to ask about server-side license records associated with your purchases.

9. Children's Privacy

The app is not directed to children under 13. If you believe a child has provided personal information to us, contact us so we can take appropriate action.

10. Health and Safety Notice

Resonance Lab is an audio creation and wellness tool. It is not medical advice, diagnosis, treatment, or a substitute for professional care. Effects vary by person. Stop listening if you feel discomfort, dizziness, anxiety, headache, or unusual symptoms. Do not use the app while driving, operating equipment, or in any situation where reduced awareness could put you or others at risk.

11. Changes to This Policy

We may update this Privacy Policy from time to time. The updated policy will be posted at this page with a new effective date.
