Important — Not a Medical Device: Tinnitus Masker plays masking sounds for relaxation, focus, and sleep. It is not a medical device and is not intended to diagnose, cure, mitigate, treat, or prevent tinnitus or any disease. Nothing in the app is medical advice. Talk to a clinician about persistent tinnitus — especially if it is one-sided, pulsatile, or sudden.
Welcome to Tinnitus Masker! These Terms of Service ("Terms") govern your use of the Tinnitus Masker mobile application ("App"). By downloading, installing, or using the App, you agree to be bound by these Terms. If you do not agree to these Terms, do not use the App.
The App is owned and operated by AZ Computing Ltd ("we," "us," or "our"), a company registered in Hong Kong.
Tinnitus Masker is a sound-mixing application designed to play masking sounds — generated noises and nature loops, all synthesized on your device — through a layered mixer, with a frequency matcher to help you find sounds that feel right for your ears, an optional notched-sound listening preference, and a sleep timer with gentle fades. The App works entirely on your device: no account, no cloud services, and no internet connection is required for playback.
The App provides sounds for relaxation, focus, and sleep. It does not measure, diagnose, or treat any condition, and the frequency matcher is a preference tool, not a medical assessment.
Your use of the App is subject to the following:
You must be at least 13 years old to use the App. By using the App, you represent and warrant that you meet this age requirement. If you are under 18, you represent that your parent or legal guardian has reviewed and agreed to these Terms.
Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to download, install, and use the App on iOS devices that you own or control, solely for your personal, non-commercial use.
You may not:
Tinnitus Masker offers a free tier and paid plans:
Purchases are processed through the Apple App Store. By purchasing, you agree to Apple's terms and conditions.

Mixes, settings, and your matched pitch are stored locally on your device. You are responsible for your device's backups; we cannot recover app data that was never transmitted to us. Deleting the app deletes this data permanently.
The App and its original content, features, and functionality are owned by AZ Computing Ltd and are protected by international copyright, trademark, patent, trade secret, and other intellectual property laws.
The sounds in the App are synthesized on your device using the App's own engine. You may play them for personal listening; you may not redistribute recordings of them as sound libraries or sample packs.
THE APP IS PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.
We do not warrant that:
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL AZ COMPUTING LTD, ITS DIRECTORS, EMPLOYEES, PARTNERS, AGENTS, OR AFFILIATES BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING WITHOUT LIMITATION:
This limitation applies whether the alleged liability is based on contract, tort, negligence, strict liability, or any other basis, even if we have been advised of the possibility of such damage.
You agree to indemnify, defend, and hold harmless AZ Computing Ltd and its officers, directors, employees, agents, and affiliates from and against any claims, liabilities, damages, losses, and expenses, including reasonable legal fees, arising out of or in any way connected with your access to or use of the App or your violation of these Terms.
We may terminate or suspend your access to the App immediately, without prior notice or liability, for any reason, including if you breach these Terms.
Upon termination, your right to use the App will immediately cease. You may terminate your use of the App at any time by deleting it from your device.
These Terms shall be governed by and construed in accordance with the laws of Hong Kong, without regard to its conflict of law provisions.
Any disputes arising from these Terms or your use of the App shall be resolved through good faith negotiation. If negotiation fails, disputes shall be submitted to the exclusive jurisdiction of the courts of Hong Kong.
We reserve the right to modify or replace these Terms at any time. If we make material changes, we will provide notice through the App or by updating the "Last updated" date at the top of these Terms.
Your continued use of the App after any changes constitutes acceptance of the new Terms.
If any provision of these Terms is found to be unenforceable or invalid, that provision will be limited or eliminated to the minimum extent necessary, and the remaining provisions will remain in full force and effect.
