Privacy Policy
Last Updated: [8/22/2026]
Welcome to Echo Player - Music, MP3 & Equalizer. We are committed to safeguarding your personal information while providing you with the best audio experience. This Privacy Policy governs the Android applications we develop and publish on the Google Play Store—including our Volume booster, equalizer, and bass booster apps (collectively, "our Apps").
This document outlines our practices regarding the collection, utilization, protection, and sharing of your data. If you have any inquiries regarding this policy, please reach out to us at creativedigger13@gmail.com.
1. How We Collect and Utilize Your Information
The specific data we collect depends on your device settings, how you interact with our Apps, and the features you use. We gather data to ensure app functionality, optimize performance, provide customer support, and deliver customized advertising.
-
Automatically Gathered Data: When you launch or use our Apps, we (and our third-party partners) may automatically log technical details. This includes your IP address, network card (MAC) address, international mobile device identification code (IMEI), independent device identifier, advertising IDs (such as Android Ad Master Identifier or GAID), operating system version, device model and manufacturer, timestamp, session start/stop times, language and time zone, network state (e.g., Wi-Fi), and hardware stats like CPU and battery usage.
-
Information You Actively Provide: If you contact us for support, provide feedback, or upload files within specific app features, we process this information strictly to fulfill your request.
-
Purpose of Processing: We utilize this data to fulfill our contractual obligations (running the App), improve your user experience, diagnose crashes, prevent fraud, and serve personalized advertisements based on your consent and our legitimate interests.
2. Device Permissions Required
To deliver core functionalities like volume boosting and audio equalization, our Apps require specific device access. We strictly limit our access to what is necessary.
|
Required Device Access |
Purpose and Privacy Assurance |
|
Battery Optimization ( |
Ensures that our equalizer and volume booster services run smoothly in the background without being unexpectedly terminated by the Android operating system. |
|
Microphone ( |
Essential for detecting audio output to apply bass boosting, equalization, and volume enhancements. Assurance: We process this audio locally in real-time; we do not record, upload, or store your audio data. |
|
Draw Over Other Apps |
Allows our app to display a user-friendly floating control interface over other applications so you can easily adjust audio settings on the fly. |
|
Notifications |
Enables seamless playback control and status updates directly from your device's notification panel. We do not read or store your personal notification content. |
3. Data Processing, Storage, and Security
Local vs. Cloud Processing: For the vast majority of our audio features, data processing (including audio analysis) occurs locally on your device. We do not upload your personal media files to our servers. Certain analytics and advertising data, however, are transmitted securely to our third-party service providers.
Security Safeguards: We employ robust technical and administrative measures to protect your information against unauthorized access or disclosure. While we strive for absolute security, no digital transmission is entirely foolproof.
Retention & Deletion: We hold your data only for the duration necessary to provide our services, comply with legal obligations (such as tax or accounting laws), and resolve disputes. You may request the deletion of your personal data at any time by contacting creativedigger13@gmail.com. Local app data can also be cleared by uninstalling the application.
4. Subscriptions and Payments
Certain Apps within our portfolio may offer premium unlocked features through subscriptions or in-app purchases. All transactions are securely handled by Google Play Billing.
-
Subscription Rules: Subscriptions typically auto-renew unless canceled prior to the end of the current billing cycle.
-
Payment Data: We do not directly collect, process, or store your credit card information. All financial processing is governed by Google’s privacy practices.
5. Third-Party Services and SDKs
To monetize our Apps and understand user behavior, we integrate specialized third-party Software Development Kits (SDKs). Not every App uses all the SDKs listed below, but depending on the App you use, these providers may collect network information, advertising IDs, and usage statistics.

Google's primary ad monetization platform. Uses IP addresses and advertising IDs to deliver banners, interstitials, and rewarded ads, as well as estimate general location. |

6. Global Privacy Rights (GDPR & CCPA)
We respect user privacy rights globally.
For European Economic Area (EEA) Users (GDPR):
We process your personal data based on contractual necessity, legal obligations, legitimate business interests, or your explicit consent.
-
Your Rights: You possess the right to request access to, rectification of, or erasure of your personal data. You may object to or restrict processing, request data portability, and withdraw consent at any time (e.g., via the Google UMP consent dialogue in our Apps).
-
International Transfers: When data is transferred outside the EEA, we rely on approved mechanisms like Standard Contractual Clauses to ensure it remains protected.
For California Residents (CCPA/CPRA):
You have the right to know what personal information is collected, request its deletion, and opt out of the "sale" or "sharing" of your data. We do not sell data for monetary compensation. However, sharing advertising IDs with ad networks may be classified as "sharing" under California law. You can opt out of personalized ads via your Android device settings or our in-app privacy tools.
