Privacy Policy

Effective date: 2026-02-09

This policy explains how dB Meter handles information. We follow a data minimization approach and do not sell user data.

Information We Use

• Microphone access: used for real-time sound analysis and recording. Audio is processed and stored locally or in your iCloud and is not uploaded to our servers.
• Location (optional): used to tag measurements and reports. Location data is stored locally or in your iCloud.
• iCloud sync (optional): if enabled, your data syncs through Apple iCloud.
• Feedback (optional): if you contact us via in-app feedback, we may receive the content you provide.

Third-Party SDK (Analytics)

We use the Umeng Analytics SDK (Umeng+) to measure daily active users and usage statistics.

• SDK: Umeng Analytics SDK (Umeng+)
• Purpose: analytics (DAU and usage statistics)
• Data types: device information/identifiers (e.g., IDFA/IDFV, Android ID/OAID as applicable), network information, and coarse location (if enabled).

• Privacy Policy: https://www.umeng.com/page/policy

Sharing

We do not sell or share your personal information with third parties, except to provide iCloud sync or analytics services, or when required by law.

Storage & Retention

Your measurements and recordings remain on your device or iCloud until you delete them or remove the app. Analytics data is processed and stored by the third-party SDK.

Security

We rely on system-level permissions and local storage. While no method is perfect, we continuously improve protections.

Your Choices

You can revoke microphone or location permissions in system settings and delete records in the app at any time.

Third-Party Services

iCloud and Umeng Analytics are provided by third parties. Please refer to their policies for details.

Changes

We may update this policy and will post the updated version on this page with a new effective date.
