# Privacy & security

> How Resonant keeps your voice data private and secure with local-first processing and zero data retention.

## Local-first by design

Resonant processes all audio on your device. Your voice is never uploaded to a server for transcription. The speech-to-text models run locally using your device's hardware:

* **Mac:** Apple Neural Engine (ANE) for maximum performance
* **Windows:** CPU or GPU inference using optimized local models

## What stays on your device

| Data               | Location                       |
| ------------------ | ------------------------------ |
| Audio recordings   | Local only — never uploaded    |
| Transcripts        | Local database on your machine |
| Meeting recordings | Local only                     |
| Journal entries    | Local only                     |
| Ambient context    | Local only                     |
| Voice models       | Downloaded once, run locally   |

## What leaves your device (opt-in only)

These features are optional and clearly marked in the app:

| Feature                        | What's sent                 | When                          |
| ------------------------------ | --------------------------- | ----------------------------- |
| **Cloud Cleanup** (Pro)        | Transcript text (not audio) | When you enable Cloud Cleanup |
| **Meeting Distillation** (Pro) | Transcript text (not audio) | When you request a summary    |
| **Cloud Sync** (Pro)           | Encrypted transcripts       | When you enable sync          |
| **Account & billing**          | Email, subscription status  | When you create an account    |

## Zero data retention

When transcript text is sent to cloud LLMs for cleanup or summarization, it is processed in real-time and not stored. Resonant uses zero-data-retention API agreements with all LLM providers.

## No telemetry on audio

Resonant collects basic app usage telemetry (feature usage, crash reports) via PostHog, but **never** collects or transmits audio data, transcript content, or meeting recordings.

## HIPAA Mode

For healthcare and high-security environments, Resonant offers a HIPAA-compatible configuration:

* All cloud features disabled
* Local-only encryption for stored transcripts
* Audit logging for access events
* No telemetry of any kind
