App Name: Decibel Monitor Pro
Effective Date: May 15, 2026
Last Updated: May 15, 2026
📋Overview
Thank you for using Decibel Monitor Pro (the "App"). This App is developed by an independent developer to provide users with professional ambient noise and sound level monitoring.
We take your privacy seriously. This Privacy Policy explains how the App handles your information. Please read this policy carefully before using the App.
Core commitment: This App does not collect or upload any personally identifiable information. Audio data is recorded and stored locally on your device for playback purposes only, and never transmitted to any server or third party.
🎤Microphone Permission
The App requires access to your device's microphone. This is the only permission necessary to deliver the core decibel-monitoring functionality.
- Purpose: To capture ambient sound signals in real time and calculate and display decibel (dB) readings. The App also supports recording and saving sound level data locally for in-app playback.
- Processing: Recorded sound level data is stored locally on your device only and is never uploaded to any server or third party.
- Retention: Recorded files are stored in your device's local storage. You can delete them at any time within the App or by clearing the App's data.
We record and save sound level data locally to support the playback feature. This data is never uploaded to any server or shared with any third party.
📊Data We Collect
The App does not collect any of the following:
- Name, email address, or other personally identifiable information
- Location data (GPS or network-based)
- Unique device identifiers (IMEI, Advertising ID, etc.)
- Contacts, call logs, or SMS messages
- Photos, videos, or other media files
- Audio recordings or voice content (the App records sound level data locally for playback, but never uploads it)
Data that may be stored locally on your device only:
- User-defined app settings (e.g., display units, alert thresholds)
- Historical decibel measurement logs and recorded sound level playback data saved by the user (stored locally only, never uploaded)
This local data is entirely under your control and can be deleted at any time by clearing the app's data or uninstalling the App.
🔗Third-Party Services
The App may integrate the following third-party services, each governed by its own privacy policy:
- Google Play Services: Used for app distribution and updates, subject to Google's Privacy Policy.
- Google AdMob (if applicable): Used to display advertisements. AdMob may collect your device's advertising identifier to serve relevant ads. You can opt out of personalized ads in your device settings.
- Firebase Crashlytics (if applicable): Used to collect anonymous crash reports to help us improve app stability. No personal information is included.
🔒Data Security
Because the App does not collect or transmit personal data, the risk of a data breach is minimal. We take the following measures to protect your security:
- All audio processing is performed locally on your device with no network transmission.
- The App requests only the permissions necessary for its core functionality.
- We regularly update the App to address potential security vulnerabilities.
👶Children's Privacy
This App is not directed at children under the age of 13, and we do not knowingly collect personal information from children. If you are a parent or guardian and believe your child has provided us with personal information, please contact us immediately and we will take prompt action.
⚖️Your Rights
Because the App does not collect personal data, most data rights (access, correction, deletion) apply naturally to the local data on your device. You may:
- Revoke microphone permission at any time in your device settings (note: core functionality will be unavailable without it).
- Delete all locally stored data by clearing the App's data or uninstalling the App.
- Opt out of personalized advertising in your device settings (if applicable).
🔄Policy Updates
We may update this Privacy Policy from time to time. When we do, we will post the revised version on this page and update the "Last Updated" date. We encourage you to review this policy periodically. Your continued use of the App after any changes constitutes your acceptance of the updated policy.
