Terms of Use

Last updated: 23 August 2026 · This is the end user licence agreement (EULA) for Grille.

Please read these terms before using Grille. By downloading or using the app you agree to them. If you do not agree, do not use the app.

Safety notice — please read

Grille deliberately plays loud, low-frequency audio at high volume.

Never use Grille while wearing headphones or earphones. The app blocks playback when it detects them, but you remain responsible for checking.
Keep the device away from your ears, from other people's ears, and from pets, whose hearing is more sensitive than ours.
Stop immediately if you experience discomfort, ringing in the ears or pain.
If you have a hearing condition, a cochlear implant, or a pacemaker or other implanted device, consult a professional before use.

1. What Grille is — and is not

Grille plays engineered tones through your device speaker. Sound pressure from those tones may help move water droplets or loose dust out of a speaker grille. That is the whole of what the app does.

Grille is not a repair service and not a diagnostic tool. It:

cannot repair a water-damaged device;
cannot remove water from anywhere other than the speaker opening;
cannot guarantee that any water or dust will be removed;
is not a substitute for professional service if your device has been submerged or is malfunctioning.

Results vary by device model, by how much liquid is present and by how long it has been there. If your device has been exposed to liquid, follow the manufacturer's guidance and seek professional service where appropriate.

2. Licence

We grant you a personal, non-transferable, non-exclusive, revocable licence to use Grille on devices you own or control, as permitted by the App Store Terms of Service or Google Play Terms of Service. You may not copy, modify, reverse-engineer, redistribute or resell the app or any part of it, except where that restriction is prohibited by applicable law.

3. Subscriptions and payment

Grille Pro is available as an auto-renewing subscription or a one-time purchase.

Payment is charged to your Apple ID or Google account at confirmation of purchase.
Auto-renewing subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period.
Your account is charged for renewal within 24 hours prior to the end of the current period, at the price shown at purchase.
You can manage or cancel your subscription in your device's account settings after purchase.
Where a free trial is offered, any unused portion of the trial is forfeited when you buy a subscription.
Prices are shown in the app before purchase and may vary by region and over time.

Refunds are handled by Apple or Google under their own policies, not by us. We cannot issue refunds directly.

4. Free tier and ads

The free tier includes a limited number of cleaning sessions per day and displays advertising. Purchasing Pro removes both limits and ads. We may change the limits of the free tier over time; existing paid entitlements are not affected.

5. No warranty

Grille is provided "as is" and "as available", without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose and non-infringement, to the fullest extent permitted by law. We do not warrant that the app will be uninterrupted, error-free, or effective for your particular device.

6. Limitation of liability

To the fullest extent permitted by law, we are not liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of data, device damage, hearing damage arising from misuse contrary to the safety notice above, or loss of profits, arising out of your use of Grille. Our total liability for any claim relating to the app is limited to the amount you paid for it in the twelve months before the claim.

Nothing in these terms excludes liability that cannot lawfully be excluded, including liability for death or personal injury caused by negligence, or your statutory rights as a consumer.

7. Third-party services

Grille uses RevenueCat to manage subscriptions and Google AdMob to serve ads. Your use of the app is also subject to those services' terms. See our Privacy Policy for what each one processes.

8. Terms specific to the Apple App Store

Where you obtained Grille from the App Store, the following apply:

This agreement is between you and us, not with Apple. Apple is not responsible for the app or its content.
We alone are responsible for providing maintenance and support for the app. Apple has no obligation to provide either.
If the app fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the app.
We, not Apple, are responsible for addressing any claim that the app or your use of it infringes a third party's intellectual property rights, or fails to conform to legal or regulatory requirements, or arises under consumer protection or similar legislation.
You represent that you are not located in a country subject to a US Government embargo or designated as "terrorist supporting", and that you are not on any US Government list of prohibited or restricted parties.
Apple and its subsidiaries are third-party beneficiaries of this agreement and, upon your acceptance, will have the right to enforce it against you.

9. Changes

We may update these terms. Material changes will be reflected by the date at the top of this page. Continuing to use the app after a change means you accept the updated terms.

10. Governing law

These terms are governed by the laws of the Republic of Azerbaijan, without regard to conflict-of-law rules. This does not deprive you of the protection of mandatory consumer-protection rules of the country where you live.
