1. Overview
Speaker Cleaner: Water Eject (“the App”), formerly published as “Speaker Cleaner & Sound Test”, is developed and maintained by Gobaith Technologies.
This Privacy Policy explains what information we collect, how we use it, and your rights regarding your data.
We are committed to protecting your privacy. We do not sell your data to anyone.
The App is free and is supported by ads (Google AdMob). You can remove all ads by purchasing the optional Speaker Cleaner Pro in-app purchase.
Important update (July 2026): The App no longer offers sign-in or user accounts. Google Sign-In and Firebase Authentication have been completely removed. We no longer collect your name or email address.
2. Information We Collect
a) No Account, No Sign-In
The App does not allow you to create an account, and there is no login of any kind.
We do not collect your name, email address, phone number, or any other identifying personal information.
Every feature of the App works without an account.
b) App Usage Data (Stored Locally on Your Device)
The following data is stored only on your device and is never transmitted to our servers:
- Cleaning session history — date, duration and type of each clean you run
- Speaker health score — a calculated score based on your cleaning history
- Audio quality results — your 👍/👎 ratings from the Audio Quality Check tool
- App preferences — theme (light/dark/system), reminder settings
This data does not leave your device unless you explicitly share it (e.g. using the Share Result Card feature).
You can erase all of it at any time via Settings → Data & Privacy → Clear app data.
c) Microphone Access
The Microphone Test tool records audio temporarily on your device for immediate playback.
Recordings are stored in your device’s temporary folder and are never uploaded anywhere.
They are processed entirely on your device.
We access your microphone only when you actively use the Microphone Test screen.
We do not record audio in the background.
d) Notifications
If you enable Cleaning Reminders, the App schedules local notifications on your device.
These are processed entirely on-device. No notification data is sent to our servers.
e) Advertising Data (Google AdMob)
The App displays banner and interstitial ads provided by Google AdMob. To deliver and measure ads, Google may collect and process:
- Advertising ID — a resettable device identifier used for advertising
- Device & ad-interaction data — such as device type, operating system, language, general (approximate, IP-based) location, and how you interact with ads
This data is collected and processed by Google in accordance with the Google Advertising policies (https://policies.google.com/technologies/ads) and the Google Privacy Policy (https://policies.google.com/privacy).
For users in the European Economic Area (EEA), the United Kingdom and Switzerland, the App shows a consent message (via Google’s User Messaging Platform) before serving personalized ads. If you do not consent, you will see non-personalized ads instead. Purchasing Speaker Cleaner Pro removes all ads.
f) Purchase Data
If you buy Speaker Cleaner Pro, purchase data is processed by Google Play Billing and RevenueCat. See Section 6 for details.
3. Information We Do NOT Collect
- We do not collect your name, email address or any account information — the App has no accounts
- We do not collect precise GPS location data (AdMob may infer an approximate, IP-based location only to serve ads)
- We do not upload your microphone recordings — they never leave your device
- We do not use third-party behavioral or usage analytics trackers
- We do not use crash-reporting SDKs
- We do not access your contacts, photos, files or camera
- We do not monitor your usage in the background
- We do not sell or rent your personal data to anyone
4. How We Use Your Information
| Data | Purpose |
|---|---|
| Cleaning history & health score | Display your cleaning log and calculate speaker health (on-device only) |
| Audio quality results | Show your latest diagnostic result in Speaker Health (on-device only) |
| Preferences | Restore your theme and reminder settings across sessions (on-device only) |
| Microphone recording | Immediate playback in the Microphone Test tool only (on-device only) |
| Purchase history & purchase ID | Unlock and verify Pro features; restore your purchase; prevent fraud |
| Advertising ID & ad data | Display ads in the App and measure ad performance (via Google AdMob) |
We use your data only to operate the App’s features and to display ads as described above. We do not use your cleaning, health or microphone data for advertising or profiling.
5. Data Sharing
We do not sell or rent your personal data. We only share data with the trusted service providers that operate the App’s core functions on our behalf, and only as needed:
- Google AdMob (Google) — displays ads in the App and may use your Advertising ID and device/ad-interaction data to serve and measure ads. How Google uses advertising data: https://policies.google.com/technologies/ads
- Google Play Billing (Google) — securely processes your in-app purchase. https://policies.google.com/privacy
- RevenueCat — manages and verifies your in-app purchase and Pro entitlement; receives your purchase history and an anonymous purchase identifier. RevenueCat Privacy Policy: https://www.revenuecat.com/privacy
- Legal Requirement — we may disclose data if required by law or valid legal process.
6. Purchase Information (In-App Purchases)
If you choose to buy Speaker Cleaner Pro — an optional, one-time in-app purchase that removes ads and unlocks Pro features — your purchase is processed by Google Play Billing and managed through RevenueCat, our in-app purchase provider.
Through these services we collect:
- Purchase history — the products you have purchased and your Pro entitlement status
- An anonymous purchase identifier — a randomly generated ID used to link your purchase to your device so your Pro status can be verified and restored. Because the App has no accounts, this identifier is not connected to your name, email or any personal profile.
We do NOT receive or store your payment card number, bank details, or billing address. All payment processing is handled securely by Google Play — we never see your financial details. This information is used only to:
- Unlock and verify your Pro features
- Restore your purchase when you reinstall the App or switch devices
- Prevent fraud and resolve purchase issues
Restoring Pro: your Pro purchase is tied to your Google Play account, not to any account in the App. To restore it on a new device, sign in to the same Google Play account, open the App and tap Pro → Restore purchase.
7. Data Retention
- Account data — none. The App has no accounts, so we hold no account data at all.
- Local data — retained on your device until you use “Clear app data” in Settings or uninstall the App
- Microphone recordings — stored temporarily on your device; cleared when you uninstall the App or clear your device’s temporary storage
- Purchase data — your purchase history and entitlement status are retained by Google Play and RevenueCat for as long as needed to provide and restore your Pro purchase, and as required for tax/accounting and fraud-prevention purposes
- Advertising data — processed and retained by Google in accordance with Google’s advertising and privacy policies; you can reset your Advertising ID at any time in your device settings
8. Your Rights & Choices
You have full control over your data:
Clear All App Data
Open the App → Settings → Data & Privacy → Clear app data.
This permanently erases all locally stored cleaning history, health scores and audio quality results from your device.
Your Pro purchase is not affected — it remains linked to your Google Play account and can be restored at any time.
Manage Ads & Advertising ID
You can reset your Advertising ID or opt out of ad personalization in your device settings (Android: Settings → Privacy → Ads, or Settings → Google → Ads).
Users in the EEA, UK and Switzerland are shown a consent choice for personalized ads; choosing not to consent results in non-personalized ads.
To remove ads entirely, purchase Speaker Cleaner Pro.
Uninstall
Uninstalling the App removes all locally stored data from your device.
Requesting Data Deletion
Because the App has no accounts and stores your usage data only on your own device, there is no personal data held on our servers for us to delete.
If you still have a question or request regarding your data, contact us at
mk021375@gmail.com
and we will respond within 30 days.
9. Children’s Privacy
The App is not directed at children under the age of 13.
We do not knowingly collect personal information from children under 13.
If you believe a child under 13 has provided us with personal information, please contact us at
mk021375@gmail.com
and we will delete it promptly.
10. Security
We take reasonable measures to protect your information:
- All data transmitted by the App (ads and purchase verification) is encrypted in transit using TLS
- Your cleaning history, health scores and microphone recordings never leave your device
- We hold no accounts and store no passwords — there is no login to compromise
- Local device data is protected by your device’s built-in security (screen lock, encryption)
11. Changes to This Policy
We may update this Privacy Policy from time to time.
When we do, we will update the effective date at the top of this page.
Continued use of the App after changes constitutes acceptance of the updated policy.
For significant changes, we will notify you via the App.
