This Privacy Policy describes how Techtenstein Services Pvt Ltd ("we," "us," or "our") collects, uses, and shares information when you use the Speaker Cleaner: Water Remover mobile application (the "App"), identified by the package name com.speaker.dustcleaner.
We are committed to protecting your privacy, especially for users in Tier 1 regions (USA, UK, Canada, and Australia) where strict data protection regulations like GDPR and CCPA apply.
The App is a utility tool designed to clear dust and water from device speakers using sound frequencies. To provide these services, we require specific device permissions.
Microphone (RECORD_AUDIO): This is used exclusively for the Mic Testing feature to measure real-time audio input levels.
Privacy Guard: We do not record, save, or transmit any audio data. Processing happens entirely on your device in real-time.
Audio Settings (MODIFY_AUDIO_SETTINGS): This allows the App to generate specific frequencies (e.g., 165Hz–200Hz) required to vibrate the speaker diaphragm and eject water.
Vibration (VIBRATE): Used to provide haptic feedback during the cleaning process to assist in physical dust displacement.
Foreground Service (FOREGROUND_SERVICE_MEDIA_PLAYBACK): This ensures the cleaning sound continues to play even if you minimize the App, preventing the system from interrupting the process.
We collect technical information such as network status (ACCESS_NETWORK_STATE) and Wi-Fi status (ACCESS_WIFI_STATE) to ensure the App functions correctly and can deliver advertising content.
To keep the App free for users, we display advertisements. These third-party partners may collect unique identifiers (like the Google Advertising ID) to serve personalized or non-personalized ads.
We integrate the following SDKs:
Google AdMob: Privacy Policy
AppLovin MAX: Privacy Policy
Meta (Facebook) Audience Network: Privacy Policy
Unity Ads : Privacy Policy
For users in the European Economic Area (EEA) and the United States, we comply with standard privacy frameworks.
Consent Management: Upon launching the App, you will be presented with a User Messaging Platform (UMP) consent form. You can choose to opt-in or opt-out of personalized advertising at any time.
No Data Sale: We do not sell your personal data to third parties.
Right to Access/Delete: You have the right to request access to or deletion of any data collected by our third-party ad partners through your device's Google Settings.
The App is not intended for use by children. We strictly target users aged 18 years or older. We do not knowingly collect personal information from children under 13 (or 16 in certain jurisdictions). If you believe we have inadvertently collected such data, please contact us immediately for its removal.
We implement industry-standard security measures to protect your information. All communications between the App and our ad partners are conducted over encrypted HTTPS connections.
