Last Updated: 16/04/2026
This Privacy Policy describes how Device Master Pro (Speaker Cleaner & Battery Fix) ("we," "us," or "our") collects, uses, and shares information when you use our mobile application. By using the app, you agree to the collection and use of information in accordance with this policy.
We do not collect any personally identifiable information (PII) such as names, phone numbers, or addresses directly. However, to provide a functional and optimized experience, we use third-party services that may collect information used to identify your device.
Information collected by third-party providers includes:
Device Identifiers: Device model, Android version, and unique device identifiers (AD-ID).
Log Data: IP address, browser type, pages of our service that you visit, the time and date of your visit, and time spent on the app.
In compliance with the 2026 Google Play Policy updates regarding data minimization, we only request permissions strictly necessary for the app’s functionality:
RECORD_AUDIO (Microphone): Used solely for the "Microphone Test" tool to measure panel responsiveness. All audio processing is done locally and in real-time on the device. We do not record, save, or transmit any audio data to our servers.
VIBRATE: Used to trigger mechanical vibration patterns required for the water ejection and speaker cleaning process.
BATTERY_STATS & SENSORS: Used to provide real-time battery health data. We do not use any location-based services or Geofencing APIs. All diagnostic processes happen locally.
PHOTO & VIDEO CLARIFICATION: This app does not access your gallery, photos, or videos.
In accordance with the updated Health and Fitness data guidelines (Android 16), this app does not access, collect, or share any sensitive health data, including but not limited to Health Connect data, cycle tracking, or symptoms.
We are committed to protecting the privacy of users in the European Economic Area (EEA). In compliance with the General Data Protection Regulation (GDPR):
Consent: We request your explicit consent via our "GDPR Protocol Overlay" upon the first launch of the app.
Non-Personalized Ads: If you do not consent to personalized advertising, we will only show non-personalized ads via Google AdMob.
Revocation: You may change your privacy preferences at any time within the App Settings.
This app uses Google AdMob to display advertisements. Google may use device identifiers to personalize ads based on your interests. You can review Google’s Privacy Policy here: https://policies.google.com/privacy
Our services do not address anyone under the age of 13. We do not knowingly collect personally identifiable information from children.
All diagnostic processes happen locally on your device in real-time. Since we do not store personal data on our own servers, the risk of data breach is minimized.
We may update our Privacy Policy from time to time to remain compliant with Google Play Store policies. You are advised to review this page periodically.
