Terms of Use — Speaker Cleaner: Water Eject

Last updated: August 14, 2026

Speaker Cleaner: Water Eject ("the app") is developed by Krillo ("we", "us"). By installing or using the app you agree to these terms. If you do not agree, please do not use the app.

What the app does

The app plays specially shaped sound frequencies through your phone's speaker to help eject water and dust from the speaker mesh, and includes a tone generator, a sound-level (dB) meter and a speaker test. It is a device-care utility.

No guarantee of repair

Water damage is unpredictable. The app can help push water out of the speaker mesh, but we cannot promise it will restore sound on every device or undo water damage. If your phone was submerged or sound does not recover, contact a professional repair service. The app plays sound at high volume by design; do not hold the phone against your ear during a cleaning cycle.

Free version and Pro

The free version includes one basic cleaning cycle per session, the tone slider, three sound-level measurements per session and one speaker test per session. Pro is an optional purchase that unlocks:

• Deep Clean — longer multi-pass cleaning cycles;
• repeated cleaning cycles without waiting for a new session;
• unlimited dB Meter measurements;
• unlimited speaker & bass tests;
• tone presets.

Purchases, trial and billing

• Purchases are sold and processed by Google Play, not by us. Prices shown in the app come from Google Play in your local currency.
• The weekly plan starts with a 3-day free trial. You are not charged until the trial ends. If you cancel before the trial ends, you are not charged at all.
• After the trial, subscriptions renew automatically for the price and period shown at purchase, until you cancel.
• The lifetime plan is a one-time purchase: pay once, it never renews and never charges again.
• You can cancel a subscription anytime in Google Play → Subscriptions. Cancellation takes effect at the end of the current billing period; you keep Pro until then.
• Uninstalling the app does not cancel a subscription. Cancel it in Google Play.
• Refunds are handled by Google Play under its refund policy. We do not process payments and cannot charge you outside Google Play.
• Purchases are tied to your Google account. "Restore" in the app re-checks that account.

Price and feature changes

We may change prices or what a plan includes for future purchases and renewals. Google Play notifies you of a price increase before it applies to your subscription, and you can cancel instead.

Acceptable use

Use the app on your own device, for personal, non-commercial purposes. Do not attempt to circumvent the purchase checks, reverse-engineer the app beyond what applicable law allows, or use it in a way that is illegal or harmful.

Availability and warranty

The app is provided "as is". Speaker loudness, frequency response and water resistance vary between devices, and results depend on how much water entered the device and where. To the extent permitted by law, we are not liable for indirect or incidental damages. Nothing here limits rights you have under mandatory consumer law in your country.
