Terms of Use

Last updated: 7 November 2026

These terms apply when you download or use Dog Whistle & Clicker Training, an app from Itworked Systems, a company registered in Türkiye. By using it, you agree to them. If you downloaded the app from Apple's App Store, Apple's standard license agreement applies as well.

Using the app

We give you a personal, non-commercial right to use the app on devices you own or control. Please don't copy, resell or redistribute it. We may change or improve features with updates.

Use sound responsibly

Dogs and many other animals hear high pitches much better than people do, and a tone you can barely hear can be loud to them. Start at a low volume, keep the phone's speaker at least an arm's length from any ear, human or animal, and use short signals.
Use the whistle and the clicker only as cues for reward-based training. Do not use them to frighten, punish or disturb animals or people, including other people's pets.
Stop if an animal shows signs of stress, such as lip licking, turning away, a tucked tail or trying to leave.
The training guide gives general information. It is not a substitute for a qualified trainer or for a vet's advice about your animal's health or behavior.

What the app can and cannot do

The app plays tones through your phone's speaker. What you and your dog hear depends on the speaker: many phone speakers get much quieter above about 18 kHz, and the highest pitch the app offers depends on your phone's audio hardware.
A whistle is a training cue. It does not change an animal's behavior on its own, and we make no promise about any result of training.

Dog Whistle Pro

The whistle, the clicker, three saved cues and the basic lessons are free. Dog Whistle Pro unlocks extra features (the pattern editor, warble and sweep tones, all whistle commands, unlimited saved cues, more clicker sounds and the advanced lessons). It is sold through Apple or Google, under their terms, as a weekly or yearly subscription or a one-time lifetime purchase. The price and any free trial are shown in the app before you buy.
Subscriptions renew automatically at the same price until you cancel. Cancel at least 24 hours before the end of the current period in your App Store or Google Play account settings; you keep Pro until the period ends. If a free trial is offered and you don't cancel before it ends, the subscription starts and is charged.
Lifetime Pro stays unlocked. On a new phone, tap Restore purchases on the Pro screen or in Settings, signed in with the same Apple Account or Google account.
If Pro ends, your saved cues stay on your phone; cues that use Pro sounds are kept but need Pro to play.
Refunds are handled by Apple or Google under their refund rules. This does not limit any rights you have under the law of your country.

The app is ours

The app, its design, sounds, lessons, icon and name belong to Itworked Systems. Some parts are open-source software and fonts used under their own licenses.

Our responsibility

We provide the app as it is, and cannot promise that it will always work on every phone or be free of errors. As far as the law allows, we are not responsible for damage or losses that come from using it, such as harm caused by playing sounds too loudly or too close to an ear. Nothing in these terms limits responsibility that the law does not allow us to limit, or your rights as a consumer.

Changes to these terms

If we change these terms, we update this page and the date at the top.

Law

These terms are governed by the laws of the Republic of Türkiye, and disputes go to the competent courts and enforcement offices of Türkiye. If you are a consumer, you also keep the protection of the mandatory laws of the country where you live, and you can take a dispute to the courts or consumer bodies there.
