Privacy Policy

Last updated: August 2026 • DZ MATRIX (UEN 53530362M)

1. On-Device Processing Commitment

DZ MATRIX develops ClearTone with a privacy-first, on-device audio architecture. All speech enhancement and noise suppression neural networks execute directly on the user's device. Zero ambient audio or conversational recordings are ever stored or transmitted to external servers.

2. Data Collection and Usage

We do not collect health data, voice recordings or private conversations. The ClearTone app does send a device identifier for trial and licence checks, and the Android app sends standard usage statistics. The full ClearTone privacy policy, including what we collect and how long we keep it, is at cleartone.dzmatrix.com/privacy.
