Privacy Policy

Last Updated: March 23, 2026

1. Introduction

Reductinn ("we," "us," or "our") provides a mobile application and related website content focused on tinnitus self-management. This Privacy Policy explains what information the current app and website process, how that information is used, and what choices you have.

2. Account Options

You can use core parts of the Reductinn app without creating an email and password login. The app may still create an anonymous backend identifier so it can save progress for your device. If you want to sync progress across devices, you may optionally create an email/password account inside the app.

3. Information We Process

  • Anonymous app identifier: When the app starts, it may create an anonymous backend identifier so it can store and retrieve your progress. This identifier is not your name or email address.
  • Account credentials: If you choose to create an email and password login, our authentication providers process your email address and authentication data needed to sign you in to your Reductinn account.
  • Course and assessment data: We may store lesson progress, completion state, and tinnitus assessment scores such as THI results so the app can show your history and progress over time.
  • Purchase and entitlement data: If you unlock paid content, we may receive transaction or entitlement status information from Apple, Google, and our purchase infrastructure providers so the app can determine whether premium content should be available.
  • Diagnostics and usage signals: We use service providers such as Firebase Crashlytics and Firebase Analytics to receive crash reports, error diagnostics, and limited app-usage events that help us improve reliability and understand how the app is being used.
  • Device-stored preferences: The app stores certain settings locally on your device, such as theme preference, first-run state, review prompt state, and downloaded audio files needed for offline playback.
  • Direct communications: If you email us directly, we will receive the information you include in that message, such as your email address and the contents of your request.

4. How We Use Information

  • To operate the app and restore your progress across sessions.
  • To authenticate optional email/password accounts and sync data across devices.
  • To display assessment history and progress trends.
  • To unlock and restore paid entitlements.
  • To troubleshoot crashes, bugs, and performance issues.
  • To understand general product usage and improve the app.
  • To respond when you contact us for support.

5. How Information Is Shared

We do not sell personal information. We may share information only with service providers or in the situations below:

  • Infrastructure providers: Services such as Firebase may process anonymous identifiers, progress records, assessment data, crash diagnostics, and analytics signals on our behalf.
  • Purchase providers: Apple, Google, and purchase-management providers such as RevenueCat may process transaction and entitlement data so in-app purchases can function correctly.
  • Legal or business events: We may disclose information if required by law, to protect rights or safety, or in connection with a merger, acquisition, or asset sale.

6. Retention and Deletion

  • On-device data: Local settings and downloaded files remain on your device until you delete the app, clear app storage, or remove the files yourself.
  • Cloud-backed records: Account-linked progress, assessment, analytics, and entitlement records may remain in our service-provider systems for as long as needed to operate the app, maintain security, comply with law, or resolve disputes.
  • In-app deletion: If you still have access to the app, you can initiate deletion from Settings > Delete Account.
  • Public deletion page: If you no longer have access to the app, you can request deletion through https://reductinn.com/account-deletion or by emailing contact@reductinn.com. If you used guest mode, include the Support ID shown in the app's Settings screen. Without it, we may not be able to verify and locate the correct guest record safely.
  • Retention exceptions: Some records may be retained when we or our providers must keep them for legal, accounting, security, fraud-prevention, or operational reasons. For example, app-store purchase history may continue to be retained by Apple, Google, or payment providers.

7. Security

We use reasonable safeguards designed to protect the information processed by the app and website. No storage or transmission system is completely secure, and we cannot guarantee absolute security.

8. Children’s Privacy

Reductinn is not intended for children under 13. If you believe a child has provided us information in connection with the app or website, please contact us and we will investigate.

9. International Transfers

Our service providers may process data in the United States or other jurisdictions where they operate. By using Reductinn, you understand that information may be processed outside your home jurisdiction.

10. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will post the revised version here and update the "Last Updated" date above.
