# Privacy & Security

How klarvoice protects your data — explained transparently.

## Local Processing

klarvoice processes your audio primarily on your device. The app captures your voice, transcribes the text, and inserts it — all locally. No permanent recordings, no audio files on external servers.

## What Gets Sent?

Depending on the selected model, an encrypted audio stream may be sent to our servers for transcription:

- **Speed model:** Local processing, no data transfer
- **Standard model:** Encrypted stream, deleted immediately after transcription
- **Precision model:** Encrypted stream, deleted immediately after transcription

In no case is audio data stored or used for training purposes.

## Data Storage

- **Transcriptions:** Stored exclusively on your device (in History).
- **Dictionary:** Stored locally and optionally synced encrypted with your account.
- **Settings:** Stored locally.
- **Account data:** Email address and billing information are securely stored on our servers.

## Encryption

- **In transit:** TLS 1.3 for all connections to our servers.
- **At rest:** AES-256 encryption for all server-side stored data.
- **Audio stream:** End-to-end encrypted during transmission, no intermediate storage.

## GDPR Compliance

klarvoice is fully GDPR compliant:

- Server location: **EU (Germany)**
- No sharing with third parties
- Data access and deletion available at any time
- Data processing agreement per Art. 28 GDPR
- Data protection officer appointed

## Deleting Your Data

1. **Delete history:** Settings → History → Delete All
2. **Delete dictionary:** Settings → Dictionary → Delete All Entries
3. **Delete account:** Settings → Account → Delete Account and All Data

When deleting your account, all server-side data is permanently removed within 30 days.

> **Our promise:** Your voice belongs to you. We don't store recordings, sell data, or use your speech for training. Privacy isn't a feature — it's our foundation.
