These Terms of Use (the “Terms”) apply to Tone Generator: Frequency Test (the “App”). By downloading, installing, accessing, or using the App, you agree to these Terms. Do not use the App if you do not agree.
The App is a local audio utility that generates tones, frequency sweeps, white noise, pink noise, and brown noise. It offers controls for frequency, output level, balance, channels, playback duration, and presets.
The App does not provide medical services, hearing diagnosis, treatment, certified calibration, or professional measurement services. Audio output accuracy can be affected by your device, operating system, headphones, speakers, connection method, and environment.
You are responsible for using the App at a safe and reasonable volume. Start at a low volume and increase gradually. Prolonged, loud, or high-frequency playback can cause discomfort or injury. Stop use immediately if you experience discomfort, ringing, or pain, and consult a qualified professional when appropriate.
You are responsible for confirming that your headphones, speakers, amplifiers, and other equipment are suitable for the selected output level. Do not use the App in a manner that could affect safety while driving, operating machinery, or performing another activity that requires your full attention.
Subject to these Terms and applicable law, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to use the App for personal, non-commercial purposes on Apple devices that you own or control.
Except where applicable law expressly permits it, you may not copy, modify, reverse engineer, decompile, rent, sell, distribute, bypass technical restrictions, or otherwise misuse the App.
The App may offer Pro features through auto-renewable subscriptions and a one-time purchase. Available plans, prices, trials, taxes, and billing periods are those displayed by the App Store at the time of purchase.
Weekly, monthly, and yearly plans, when designated as auto-renewable subscriptions, are charged to your Apple ID and renew automatically unless cancelled at least 24 hours before the end of the current period;
A one-time purchase does not renew automatically;
You can manage or cancel auto-renewable subscriptions in your Apple device subscription settings;
Apple handles refunds, billing disputes, and payment processing under its terms; and
Restoring purchases depends on Apple’s verification of your active purchase entitlement.
We may change free and Pro features in the future, but will not retroactively change the Apple terms or rights provided by law that applied to a completed purchase.
The App and its interface, text, graphics, audio-generation logic, and other content are protected by applicable intellectual property laws. Except for the license expressly granted in these Terms, we reserve all rights.
The App includes third-party open-source components, including SnapKit and MBProgressHUD, which are subject to their respective licenses.
We may update, modify, suspend, or discontinue the App or its features within reasonable limits. We do not guarantee that the App will remain available on every device, in every region, network environment, or future iOS version, or that it will be uninterrupted or error-free.
To the maximum extent permitted by applicable law, the App is provided on an “as is” and “as available” basis without express or implied warranties, including warranties of merchantability, fitness for a particular purpose, accuracy, or non-infringement.
To the maximum extent permitted by applicable law, we are not liable for indirect, incidental, special, consequential, or punitive damages arising from use or inability to use the App, equipment damage, volume settings, audio output, or reliance on the App’s results. Nothing in these Terms excludes liability that cannot lawfully be excluded or limited.
We may suspend or terminate your license to use the App to the extent permitted by law if you breach these Terms. You may stop using and delete the App at any time. Terms that by their nature should survive termination will survive.
We may update these Terms. The updated version will be made available in the App, on our website, or on the App Store product page and identified by the “Last updated” date. Continued use of the App constitutes acceptance of the updated Terms to the extent permitted by law.
