Terms of Service

Last updated: October 15, 2026

These Terms of Service ("Terms") are an agreement between you and Denis Salaev ("we", "us") for the iPhone app Speaker Rescue: Water Eject (the "app"). By downloading or using the app you agree to these Terms and to our Privacy Policy. If you do not agree, please do not use the app.

1. Who can use the app

You must be at least 13 years old. If you are under the age of majority where you live, use the app and make purchases only with the permission of a parent or guardian.

2. What the app does, and what it does not

Speaker Rescue plays sound through your iPhone's speaker (a low tone and a frequency sweep) to help push water and dust out of the speaker openings. It also includes tools to test your audio: a sound level meter, Noise Log, dB Camera, stereo, microphone, bass, vibration and frequency tests, a tone generator, and tips.

3. Safe use

4. Subscriptions, free trial and purchases

Most features of the app need an active subscription or a lifetime purchase. Purchases are made through the App Store and are tied to your Apple Account, not to an account with us.

5. Apple's standard EULA

In addition to these Terms, your use of the app is covered by Apple's standard Licensed Application End User License Agreement (the "Apple EULA"). If the two conflict, the Apple EULA prevails on the matters it covers. Apple is not a party to these Terms and is not responsible for the app or for supporting it; questions about the app come to us.

6. Acceptable use

We give you a personal, limited, non-exclusive, non-transferable license to use the app on Apple devices you own or control, for your own non-commercial use. You agree not to copy, modify, resell or distribute the app, to reverse engineer it (except where the law allows), to bypass or tamper with purchase checks or access limits, or to use it in any way that is unlawful or that could damage a device or hurt a person.

7. Ownership

The app, its design, sounds, text, images and the name "Speaker Rescue" belong to Denis Salaev or its licensors and are protected by law. You keep ownership of the pictures you take with dB Camera and of anything else you create.

8. Third-party services

The app works with services from Apple (App Store), RevenueCat (purchases) and PostHog (analytics). Their own terms apply to their services. How data is handled is explained in our Privacy Policy.

9. Disclaimer of warranties

The app is provided "as is" and "as available". To the fullest extent the law allows, we give no warranties of any kind, express or implied, including that the app will remove water or dust, improve your sound, give accurate measurements, or work without errors or interruption on your device.

10. Limitation of liability

To the fullest extent the law allows, we are not liable for indirect, incidental, special or consequential damages, or for loss of data or profits, or for damage to or loss of function of your device, speaker or accessories, arising from your use of the app. Our total liability for any claim is limited to the amount you paid for the app in the 12 months before the claim, or USD 50 if you paid nothing.

Nothing in these Terms limits liability that cannot be limited by law, such as liability for fraud, or for death or personal injury caused by negligence, or any rights you have as a consumer under mandatory local law.

11. Ending your use

You can stop using the app at any time by deleting it (remember to cancel any subscription as described above). We may suspend or end your access if you seriously or repeatedly break these Terms. Paid time is not refunded by us in that case, except where Apple or the law requires it.

12. Changes

We may change the app and these Terms, for example when features are added. The date at the top shows the latest version. If a change is important, we will say so in the app or on this page. If you keep using the app after a change, you accept the new Terms; if you do not agree, stop using the app and cancel any subscription.

13. Your local rights

If you are a consumer, nothing in these Terms takes away the protection of the mandatory laws of the country where you live.
