Agreement
These Terms of Use (“Terms”) govern your use of Frequency Generator Hz Tone (the “App”), published by Appcelerator Studio (“we”, “us”). By downloading or using the App you agree to these Terms. If you do not agree, do not use the App.
You must be old enough to enter into this agreement where you live. If you are not, you may use the App only with the agreement of a parent or guardian, who accepts these Terms on your behalf and is responsible for what is done with the App on their device, including any purchase.
Where you downloaded the App from the Apple App Store, Apple’s Licensed Application End User License Agreement also applies, and the section “Apple” below forms part of this agreement.
License
We grant you a personal, non-exclusive, non-transferable, revocable license to install and use the App on devices you own or control, for your own use, in accordance with these Terms and the applicable app store rules.
The license is what you receive: you are not buying the App, its code, its content or any part of it. Any right not expressly granted here is reserved.
What you may not do
You agree not to:
- Copy, modify, translate, reverse engineer, decompile, disassemble or create derivative works of the App, except where that restriction cannot be imposed under the law that applies to you.
- Rent, lease, lend, sell, sublicense, redistribute or publish the App, or make it available to several devices at once over a network.
- Remove, obscure or alter any copyright, trademark or other notice in the App.
- Bypass, disable or tamper with the App’s purchase checks, security measures or any technical limitation, or install a modified, cracked or otherwise unauthorised copy.
- Extract the App’s code, sounds, artwork or other content for use in another product or service, including to train machine learning models.
- Use the App to break the law, to infringe anyone’s rights, or in any way that could harm, disable or overload a device, network or service.
Subscriptions and payments
Some features of the App require a paid subscription. Prices and billing periods are shown in the App before you buy. Payment is charged to your app store account when you confirm the purchase.
Subscriptions renew automatically at the end of each billing period unless cancelled at least 24 hours before the period ends. You can manage or cancel your subscription in your device’s account settings (on iOS: Settings › your name › Subscriptions). Deleting the App does not cancel a subscription.
Where a free trial is offered, any unused portion of the trial is forfeited when you purchase a subscription. Refunds are handled by the app store according to its policies; we cannot issue refunds directly for purchases made through Apple, and we do not receive, see or store your payment details.
A subscription unlocks features for as long as it is active. It is not a permanent purchase of those features: if the subscription lapses or is cancelled, the paid features stop working. Prices, billing periods and what a subscription includes may change; a change applies from your next billing period, and where the law requires your agreement to a price increase, we or the app store will ask for it before it takes effect.
Purchases are validated through RevenueCat. See the Privacy Policy for details on what data this involves.
What the App is
The App is a tone generator. It plays a single tone at the frequency you choose, between 1 Hz and 22,000 Hz, in a sine, square, sawtooth or triangle wave, through your device’s speaker or connected audio output. It is a utility for jobs such as testing speakers, headphones and subwoofers, finding a reference pitch, locating feedback in a room, or playing a chosen frequency while you work or sleep.
The ring around the dial labels five frequency ranges with the names delta, theta, alpha, beta and gamma. These are names for numeric ranges, so that you can find a range by name instead of by number. They are not a claim that any frequency does anything. The App is not a medical device, makes no claim that any frequency has any effect on your health, mood, sleep, concentration or any medical condition, and is not intended to diagnose, treat, cure or prevent anything.
The App is not a hearing test. Its output is not calibrated, and whether you can hear a given tone on a given phone tells you nothing reliable about your hearing. If you are concerned about your hearing, or want to describe the pitch of tinnitus to a clinician, treat the App as a rough aid only and see a hearing professional.
Purchase required
The App requires a purchase to produce sound. The dial, the waveform selector and the power switch are shown before purchase, but nothing plays until you unlock the App with either an auto-renewing weekly subscription or a one-time lifetime purchase. Prices are shown in the App before you buy, and there is no free trial.
Lifetime means for as long as the App is offered on the App Store and supported by us. The purchase is tied to the Apple Account that made it and can be restored on a new device with Restore Purchases in the App. Refunds are handled by Apple according to App Store policies.
Hearing and equipment safety
Please read this section before you use the App. You are responsible for the volume level, for the equipment you connect, and for how and where you use the App.
- Loud sound damages hearing, and the damage is permanent. Start at a low volume, increase it gradually and keep it moderate. Be especially careful with headphones and earphones. Stop immediately if you feel discomfort, pain or ringing in your ears.
- A tone you cannot hear is not necessarily quiet. Very high frequencies may be inaudible to you while your device or speaker is still producing them at full volume. Check the volume before you choose a high frequency, and do not turn it up because you hear nothing.
- Very low and very high frequencies at high volume can damage speakers, headphones and subwoofers, especially small ones. Know the limits of your equipment and keep the volume down while testing.
- Some frequencies that you cannot hear are clearly audible, and unpleasant, to animals and to younger people. Consider who and what is within earshot before you play them.
- The tone keeps playing when you lock the screen or switch to another app, until you stop it from the App, the lock screen or Control Center. Check that it has stopped before you put the device down, connect it to a speaker or hand it to someone else.
- Do not use the App while driving, cycling or in any situation where it could distract you or mask sounds you need to hear.
- If you have a hearing condition, are sensitive to sound, or are unsure whether prolonged exposure to a tone is safe for you, ask a professional before use.
Accuracy of the tone
The frequency shown in the App is the frequency requested from your device’s audio system. What actually comes out depends on the hardware: a phone speaker cannot reproduce the lowest and highest frequencies, headphones and speakers have their own limits, and the loudness of the tone varies with frequency. Below about 20 Hz, where a phone speaker reproduces nothing, the App plays a 200 Hz tone switched on and off at the frequency you chose so that the setting is audible; the display keeps showing the frequency you chose.
The App is not a calibrated measurement instrument. Do not rely on it where an inaccurate tone could cause harm or loss without checking it against a calibrated source.
Our rights in the App
The App — its code, design, name, icon, sounds, artwork and text — belongs to us or to our licensors and is protected by copyright and trademark law. Third-party components included in the App remain the property of their authors and are used under their own licenses.
If you send us feedback, a bug report or an idea, we may use it in any way, without any obligation to you and without compensation, confidentiality or credit. Do not send us anything you want to keep confidential or be paid for.
Services we do not control
The App depends on services that are not ours, including the app store you installed it from, Apple’s or Google’s purchase systems, and RevenueCat, which validates purchases. Their own terms and privacy policies govern what they do. We are not responsible for their availability, their acts or omissions, or for any loss caused by them.
Links to other websites or apps are provided for convenience only. We do not endorse them and are not responsible for their content or practices.
Availability and changes
We may update, change or discontinue the App or any feature at any time. We will try to give reasonable notice of material changes through app store release notes.
We are under no obligation to provide updates, support, bug fixes or any particular feature, and we are not liable if the App becomes unavailable, stops working with a future operating system, or is removed from an app store. If we permanently remove a feature that your subscription paid for, your remedy is to cancel the subscription.
Disclaimer of warranties
The App is provided “as is” and “as available”, with all faults and without warranties of any kind, whether express, implied or statutory, including any implied warranty of merchantability, fitness for a particular purpose, accuracy, quiet enjoyment or non-infringement, to the fullest extent permitted by law.
We do not warrant that the App will meet your requirements, that it will run uninterrupted, on time, securely or error-free, that defects will be corrected, or that data stored by the App will never be lost or corrupted. You use the App at your own risk, and you are responsible for keeping your own backups of anything that matters to you.
Some countries do not allow the exclusion of implied warranties, so parts of this section may not apply to you. Nothing here affects rights that the consumer law of your country gives you and does not allow to be excluded.
Limitation of liability
To the maximum extent permitted by law, we are not liable for any indirect, incidental, special, punitive or consequential damages, or for lost profits, lost opportunities, or loss or corruption of data or content, arising out of or relating to the App — whether the claim is based on contract, tort, statute or anything else, and even if we knew such damage was possible.
To the maximum extent permitted by law, our total liability for all claims relating to the App is limited to the greater of the amount you paid us for the App in the twelve months before the claim arose and US$50.
Nothing in these Terms excludes or limits liability that cannot be excluded or limited by law, including liability for death or personal injury caused by negligence, or for fraud, or rights under the consumer protection law of your country.
Your responsibility
If a claim is brought against us because of the way you used the App — because you broke these Terms, broke the law, or infringed someone else’s rights — you will cover the resulting losses, damages and reasonable legal costs. This does not apply to the extent the claim results from something we did, and it does not apply where the law where you live does not permit it.
Termination
You can stop using the App at any time by deleting it. We may terminate or suspend your license if you breach these Terms; if we do, you are not entitled to a refund of unused subscription time. Sections that by their nature should survive (such as our rights in the App, disclaimers and limitations of liability) survive termination.
Apple
These Terms are between you and us. Apple is not a party to them, is not responsible for the App or its content, and has no obligation to provide maintenance or support for the App.
If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the App to you. To the maximum extent permitted by law, Apple has no other warranty obligation whatsoever with respect to the App.
We, not Apple, are responsible for addressing any claim by you or a third party relating to the App, including product liability claims, any claim that the App fails to conform to a legal or regulatory requirement, claims under consumer protection or privacy law, and any claim that the App infringes a third party’s intellectual property rights.
You confirm that you are not located in a country subject to a U.S. Government embargo or designated as a “terrorist supporting” country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.
General
If any part of these Terms is found to be unenforceable, the rest stays in force and that part is applied as closely as possible to its original intent.
Not enforcing a term is not a waiver of it. You may not transfer your rights under these Terms; we may transfer ours if the App or our business changes hands.
These Terms, together with the Privacy Policy and the terms of the app store you installed from, are the whole agreement between you and us about the App. They are written in English; any translation is for convenience only.
Changes to these Terms
We may revise these Terms from time to time. The current version is always published on this page with its “Last updated” date. Continuing to use the App after a change means you accept the revised Terms.
