Welcome to Remove Water From Speaker, a utility application developed by Roshan Varma under the organization JEWEALITY ("we", "our", or "us").

This Privacy Policy explains how our application operates, our commitment to zero personal data harvesting, and the minimal interactions our app has with device hardware and third-party advertising services (Google AdMob). By downloading, installing, or using the app, you agree to the practices outlined in this policy.

The primary purpose of Remove Water From Speaker is to help clear trapped water droplets and accumulated fine dust particles from your smartphone speaker grills.

• Acoustic Resonance: The app utilizes the device's audio hardware to generate safe, specific low-frequency sine waves and harmonic frequency sweeps (between 165Hz and 800Hz).
• Pure Synthesis: All audio tones are synthesized in real-time on your phone's processor using the Android AudioTrack API.
• No Microphone Access: We do NOT request or use the RECORD_AUDIO permission. The app cannot listen to, record, or transmit any external sounds, conversations, or environmental audio.
• Haptic Synchronization: The app uses subtle, synchronized vibration pulses to physically encourage moisture displacement without stressing internal speaker diaphragms.

Local Preferences Stored On-Device Only:
The app stores basic user interface settings locally on your device using Android DataStore / SharedPreferences:

• Theme Mode preference (System Default, Light Mode, or Dark Mode).
• Haptic Feedback toggle (Enabled / Disabled).

This data never leaves your smartphone and is deleted automatically if you uninstall the application or clear app data in your Android settings.

We strictly adhere to the principle of least privilege. The application requests only the minimum permissions necessary for its intended functionality:

We do NOT request sensitive permissions such as Camera, Contacts, Fine/Coarse Location, Storage/Media, or Microphone.

To provide this application free of charge, we display banner and interstitial advertisements served by Google AdMob (a service provided by Google LLC).

Google AdMob may collect and process pseudonymous identifiers and diagnostic data in accordance with Google's Privacy Policy, including:

• Google Advertising ID (GAID / AAID) for advertising and fraud prevention.
• Coarse device information (device model, operating system version, carrier).
• Non-precise, general network location (country or region level derived from IP address).
• Ad interaction, performance statistics, and crash diagnostics.

Opting Out of Personalized Ads:
You can reset your Advertising ID or opt out of personalized advertisements at any time through your Android device settings: Settings → Google → Ads → Reset or Delete advertising ID.

Our application is a general-audience utility and does not knowingly target or solicit personal information from children under the age of 13 (or the applicable legal age in your jurisdiction). If you are a parent or guardian and believe that your child has provided us with any information, please contact us immediately, and we will take prompt steps to address it.

Because we do not maintain external servers, user databases, or user accounts, we do not store your personal information on our infrastructure. Any ad-related telemetry handled by the Google Mobile Ads SDK is transmitted using modern encrypted protocols (HTTPS / TLS 1.3).

We may occasionally update this Privacy Policy to reflect app enhancements, updated Google Play policies, or regulatory requirements. Any modifications will be posted directly on this page with an updated "Last Updated" timestamp. We recommend checking this page periodically for updates.
