Nettoyeur HP: Eau & PoussièrePolitique de confidentialité

Effective date and last updated: September 16, 2026

This privacy policy applies to the Android mobile application Speaker Cleaner: Water & Dust (identified by package name com.umbrabyte.speakercleaner.water.eject), developed and published by Umbrabyte Apps. It complements the general Umbrabyte Privacy Policy and serves as the official privacy policy linked within the app and its Google Play Store listing.

Plain language summary: Speaker Cleaner turns your phone into an acoustic cleaning lab that expels trapped water and dust from your phone or earbud speakers using calibrated sound waves: 165 Hz water-ejection pulses, 20 Hz-20 kHz dust-removal sweeps, an 800 Hz maintenance tone, a manual tone generator and a stereo sound-test lab. Every cleaning tone is synthesized locally on your device and played through your own speaker; your cleaning session history, manual presets, speaker-health results and app preferences are stored strictly on your device. Umbrabyte operates no cloud servers, requires no user account, includes zero advertisements, runs no analytics, and never sells or rents personal data. Data only leaves your device when Google Play processes an optional PRO purchase (speakercleaner_pro_lifetime) or checks for app updates.

This summary does not replace the detailed terms set forth below.

1. Scope and key facts

Speaker Cleaner: Water & Dust is an acoustic utility that cleans phone and earbud speakers with calibrated sound waves. It provides a 165 Hz water-eject mode, a 20 Hz to 20 kHz dust-removal resonance sweep, an 800 Hz maintenance tone, a manual 20 Hz-20 kHz tone generator, a stereo sound-test audio lab, and headset tools that eject water or auto-clean earbuds.

• No account or registration required: The application does not ask you to create a user account, profile, or provide personal credentials.
• 100% on-device audio synthesis: Every tone is generated in real time by the app’s own synthesis engine (AudioTrack PCM) and played through your speaker. No audio is downloaded, streamed, or uploaded.
• Zero ads or cross-app tracking: The application contains no advertising SDKs or tracking libraries and does not use the advertising ID.
• No data sales: Umbrabyte does not sell, rent, or trade user personal information under any circumstances.
• No automated profiling: We do not perform user profiling or automated decision-making.
• Local storage only: Cleaning session history, manual presets and speaker-health results live in a private on-device Room database (AppDatabase); preferences, the daily free quota (3 cleanups per day, resetting at local midnight) and the PRO entitlement cache live in private on-device DataStore storage.
• Platform integration: The optional PRO purchase (speakercleaner_pro_lifetime, one-time lifetime purchase) is handled via official Google Play Billing APIs. Update checks use official Google Play Core APIs.
