# Privacy Policy
Effective Date: May 2026
---
1. Introduction
Welcome to Speaker Cleaner (the "App"). We are committed to protecting your
privacy and ensuring a secure experience. This Privacy Policy explains what
data we collect, how we use it, and your choices.
2. Data Collection and Usage
The App is primarily an offline utility — it uses your device's audio and
vibration hardware to generate frequencies to clean your speaker.
To improve the App's stability and user experience, we use Google Firebase,
which collects the following anonymous, non-personal data:
• Crash reports (via Firebase Crashlytics): automatic reports when the App
crashes, including device model, OS version, and stack trace. No personal
information is included.
• Anonymous usage data (via Firebase Analytics): aggregated, anonymous
events such as which features are used and session duration. This data
cannot identify you personally.
We do NOT collect any personal data — no name, email address, phone number,
photos, or any other personally identifiable information (PII).
3. Offline Functionality
The App's core cleaning functions work entirely offline without an internet
connection. Firebase data is stored locally on your device and transmitted
only when a connection is available.
4. Device Permissions
The App may request minimal permissions (audio settings, vibration) strictly
to perform speaker cleaning. These permissions are not used to collect data.
5. Third-Party Services
We use the following Google Firebase services:
• Firebase Crashlytics — automatic crash and error reporting
• Firebase Analytics — anonymous usage statistics
Data collected by these services is shared with Google and processed in
accordance with Google's Privacy Policy (https://policies.google.com/privacy).
Firebase may collect:
- A Firebase Installation ID (a random identifier, not tied to your identity)
- Device model, OS version, and app version
- Approximate location derived from IP address (country/region level only)
6. Your Choices — Opt-Out
You can disable all data collection at any time:
Open the App → Settings → "Help improve this app" → turn OFF
When disabled:
- No new crash reports or usage data will be collected
- No data will be transmitted to Firebase
- The App continues to work normally with all features
7. Data Retention
- Crashlytics data: retained by Google for 90 days
- Analytics data: retained by Google for 14 months
- Disabling data collection prevents new data from being collected but does
not delete previously collected data, which expires according to Google's
retention schedule
8. Children's Privacy
The App does not knowingly collect data from children under 13. The anonymous
data collected by Firebase does not include any personal information.
9. Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be
reflected on this page with an updated effective date.
