Privacy Policy for Tinnitus Masker

Last updated: October 6, 2026

1. Introduction

Welcome to Tinnitus Masker! We ("AZ Computing Ltd", "we", "us", "our") are committed to protecting your privacy. This Privacy Policy explains how Tinnitus Masker handles your information when you use our iOS application, and how this website (azcomputingltd.com/tinnitus) handles visits.

By using Tinnitus Masker, you agree to this Privacy Policy. If you do not agree, please discontinue use of the app.

2. Our Privacy-First Approach

Tinnitus Masker is a local-only app by design:

• No Account, No Server: The app has no login and no backend. There is nothing to sign up for and nowhere for your data to go.
• 100% On-Device Audio: Every sound — the generated noises and the nature loops — is synthesized on your iPhone. Nothing is downloaded, and playback works fully offline.
• Your Mixes Stay Local: Saved mixes, layer volumes, timer settings, and your matched pitch are stored only in the app's sandbox on your device.
• Your Matched Pitch Is Health-Adjacent: The frequency you select with the matcher is a personal listening preference. It is never transmitted anywhere — not to us, not to any analytics service.
• No Third-Party Analytics: We do not use analytics SDKs that track you or transmit behavior to any service.

3. Anonymous Usage Events (Stored On Your Device Only)

The app keeps a small, capped log of anonymous usage events — for example, that a session started or completed, or that the paywall was shown — together with a random identifier generated on your device and an install date. This helps the app show you simple usage summaries, and nothing else.

• These events are stored only on your device and are never sent to us or anyone else. There is no server to send them to.
• The log contains no audio content and never your matched frequency.
• You can see the current event count in the app's About tab, and deleting the app deletes the log permanently.

4. What the App Never Does

• No Microphone Access: The app never records or listens. The frequency matcher is a tone you compare against your own ringing — a listening preference, not a measurement — and it uses no microphone.
• No Health Data Collection: We collect no health, fitness, or medical information.
• No Location, No Contacts, No Photos: The app requests none of these permissions because it needs none of them.
• No Advertising: The app contains no ads and no ad SDKs.

5. Information We Collect

We collect no personal information through the app. The only information involved in using Tinnitus Masker is:

• Purchase Data: If you buy a plan, the transaction is processed entirely by Apple through the App Store. We never see your name, payment details, or billing information. We also do not receive a copy of your purchase status — the app reads it from Apple on your device.
• Crash Reports (Optional): If you opt in to sharing diagnostics with developers through iOS Settings, Apple may share anonymized crash reports with us. These do not contain personal information, your mixes, or your matched pitch.

6. This Website

This policy covers both the Tinnitus Masker app and this website. The website never receives anything you do in the app. These pages do not load advertising or cross-site tracking scripts, and we do not run ad-measurement SDKs on them. If that ever changes, we will update this policy before any such change goes live.

As with any website, our hosting provider's standard infrastructure may process transient request data (such as IP addresses) necessary to serve pages. The App Store buttons may be tagged with Apple's campaign parameters (pt/ct) so Apple can attribute downloads in our own App Store reports; Apple handles that attribution.

7. Data Sharing

We do not sell, trade, or share your personal data with third parties. Period.

The only external service involved is Apple's App Store for purchase and subscription management, which is governed by Apple's own privacy policy.

8. Data Security

Because your sounds, mixes, and matched pitch remain on your device, their security depends on your device's security:

• We recommend using a passcode or Face ID/Touch ID on your iPhone
• Keep your iOS updated to the latest version for security patches
• All audio processing uses Apple's secure native frameworks on your device

9. Data Retention

We do not retain your data because we do not receive it. When you delete the app, all app-related data — mixes, settings, matched pitch, and the local usage log — is removed from your device.

10. Your Rights

Since we don't collect personal data, there is no personal data for us to provide, modify, or delete. Your sounds, mixes, and matched pitch are entirely under your control on your device.

If you have questions about how your data is handled, please contact us.

11. Children's Privacy

Tinnitus Masker does not knowingly collect any personal information from children under 13. Since we collect no personal data, the app is safe for users of all ages.

12. Changes to This Policy

We may update this Privacy Policy from time to time. If we make significant changes, we will notify you through the app or by updating the "Last updated" date at the top of this policy.

Your continued use of Tinnitus Masker after any changes signifies your acceptance of the updated policy.

13. California Privacy Rights (CCPA)

If you are a California resident, you have rights under the CCPA. However, since we do not collect, sell, or share personal information, these rights are effectively already honored by our privacy-first design.
