Speaker Cleaner - Water Eject
Last updated: 28 September 2026
Matechmobile Global Limited, published on Google Play as Matechmobile Global ("we", "us"), provides Speaker Cleaner - Water Eject, Android package com.speakercleaner.water.eject (the "App"). This policy explains how information is processed when you use the App and this policy webpage. The App includes advertising and optional in-app purchases or subscriptions.
For privacy questions or requests, contact contact.matechmobile@gmail.com.
1. Information processed by the App
- Device and network information: device model, operating-system and App versions, language, IP address, advertising identifiers (where available), installation identifiers and similar identifiers. Service providers may use an IP address to infer an approximate location, such as a country or city. The App's cleaning and sound-measurement features do not require Android device-location permission.
- App activity and advertising information: installations, sessions, screens and features used, interactions with the App and ads, campaign/referral information, and advertising performance. These help us understand usage, configure features, measure advertising and detect invalid activity.
- Diagnostics: crash reports, error information and technical information about the device and App state to identify and resolve reliability problems.
- Purchase information: product identifiers, purchase tokens or receipts, transaction and subscription status, and related purchase events to provide and restore paid access, verify purchase status and measure revenue. Google Play processes payment details; we do not receive your full payment-card details through Google Play Billing.
- Notification information: app installation identifiers and push-notification tokens used by Firebase Cloud Messaging to deliver messages. Displaying notifications is subject to your device settings and any required permission.
- Information you send us: if you contact support, we receive your email address, your message and any attachments you choose to provide. Avoid sending information that is unnecessary for your request.
The information processed depends on the features you use, App version, device settings, region and applicable consent choices.
2. Microphone, camera and media
- Microphone: with your permission, the sound-level meter reads microphone samples and calculates decibel (dB) readings on your device. The measurement process handles the samples in memory to calculate sound levels.
- Camera and saved photos: with your permission, the camera feature provides a preview and lets you capture a picture with a sound-level overlay. This can include the minimum, average and maximum dB readings. The App creates a temporary image while preparing the result and saves the resulting photo to your device's photo library when you use the save feature.
- Audio library and storage: where the equalizer or audio-player feature is available, the App can access local audio files and associated media information, such as track details and album artwork. The permissions used depend on your Android version. Older Android versions may also require storage permission to save photos.
Sound calculations and photo creation take place on your device. Feature interactions may still generate usage events for the analytics and advertising services described in this policy. A saved photo can also be backed up or shared by services you choose to use.
You can deny or revoke microphone, camera, media and notification permissions in Android settings. Features that depend on a permission may not work when that permission is disabled.
3. Why we use information
We use information to provide the App's features; remember preferences and feature settings; provide and restore purchases; deliver notifications; understand and improve usage and reliability; configure features; serve and measure ads; attribute installations and purchases to campaigns; prevent fraud and misuse; respond to support and privacy requests; and meet applicable legal obligations. Where consent is required for particular processing, that processing is subject to the applicable consent requirements.
4. Third-party services and sharing
The App integrates the services below. They may receive or collect the information relevant to their roles, including identifiers, device/network information, usage events and diagnostics. Advertising and attribution services may also process approximate location, ad interactions and campaign information; purchase-related services may process purchase events and transaction identifiers. Collection depends on which services are active and your settings and choices.
- Google AdMob / Google Mobile Ads: advertising, measurement and invalid-traffic prevention. Google advertising privacy information.
- AppLovin: advertising and measurement. AppLovin Privacy Policy.
- Unity Ads and Unity's advertising quality services: advertising, measurement and ad-quality monitoring. Unity Privacy Policy.
- Google Analytics for Firebase: App usage and event analytics. Google Analytics for Firebase privacy information.
- Firebase Crashlytics, Remote Config, Cloud Messaging and related Firebase installation services: diagnostics, feature configuration and notification delivery. Firebase privacy information.
- AppsFlyer, including its purchase measurement integration: installation/campaign attribution and purchase/subscription measurement. AppsFlyer Services Privacy Policy.
- Google Play Billing: in-app purchases and subscriptions. Google Privacy Policy.
Providers may process information on our behalf or under their own privacy policies, depending on the service. We may also disclose information when required by law, to protect rights and security, or as part of a business transfer subject to applicable data-protection requirements. If you choose to share a saved file or open an external service, that recipient's practices apply to information you send there.
5. Advertising choices
Advertising services may use identifiers, approximate location and activity information to deliver or measure ads, including personalized ads where permitted. Use any consent or privacy-choice interface made available in your App version and region. You can also manage advertising-ID and ad-privacy settings through Android/Google settings; available controls vary by device and Android version. Changing these settings does not necessarily remove ads or stop all measurement or fraud-prevention processing.
6. Storage and retention
The App stores preferences and may create files on your device. You can manage local App data through Android settings and saved media through your device’s file or photo tools. Temporary files may be removed by the App or operating system. Files saved to shared storage or your photo library can remain after uninstalling and must be managed separately. Device or photo-backup services you enable may retain or restore copies under their own settings and policies.
Support correspondence is retained for as long as reasonably needed to handle your request, maintain necessary records and meet legal obligations. Data handled by analytics, advertising, attribution, diagnostics and payment providers is retained according to the relevant service's settings, purposes, privacy policy and legal requirements. Retention varies by data type; uninstalling the App does not automatically delete records already held by those providers.
7. Your privacy requests
Depending on applicable law, you may have rights to access, correct or delete personal information, restrict or object to processing, obtain a copy of your information, or withdraw consent. Contact contact.matechmobile@gmail.com, identify the App and explain your request. We may need information sufficient to locate the relevant records and verify your request. Some SDK records use device or installation identifiers rather than your name or email address, and records may not be identifiable from an email address alone. Requests are subject to applicable law and any legitimate retention requirements; we cannot promise deletion of data that we cannot identify or control. You may also exercise available rights directly with a relevant provider and contact your local data-protection authority.
Clearing App data, uninstalling the App or making a privacy request does not cancel a Google Play subscription. Manage subscriptions separately through Google Play.
8. Security and international processing
We use reasonable measures to protect information. No method of electronic transmission or storage is completely secure. Our service providers operate internationally, so information may be processed outside your country under the safeguards and terms applicable to those services and applicable law.
9. Children
The App is not directed to children under 13. If you are a parent or guardian and believe a child has provided personal information to us, contact us so we can investigate and take appropriate action under applicable law.
10. This webpage and external links
This policy webpage is hosted on Firebase Hosting and contains no advertising or analytics scripts added by us. Hosting infrastructure processes technical request information, such as IP address and browser/request details, to deliver and secure the page. External links lead to services with their own privacy practices.
11. Changes and contact
We may update this policy when the App, our practices or legal requirements change. The revised policy will be published here with an updated date; additional notice or consent will be provided where required by law.
