# On-Device Processing

> Privacy mode keeps all audio processing on your device — nothing leaves your computer.

Privacy mode is Mavio's on-device processing feature. When enabled, your meeting audio is transcribed and analyzed entirely on your local machine. No audio data is sent to Mavio's servers, giving you complete control over sensitive conversations.

## How privacy mode works

In normal mode, Mavio sends your audio to cloud servers for processing. In privacy mode, the pipeline runs entirely on your device:

| Step                    | Normal mode           | Privacy mode                                    |
| ----------------------- | --------------------- | ----------------------------------------------- |
| **Audio capture**       | Local                 | Local                                           |
| **Audio upload**        | Sent to Mavio servers | Stays on your device                            |
| **Transcription**       | Cloud AI models       | On-device AI model                              |
| **Speaker diarization** | Cloud processing      | On-device processing                            |
| **Summarization**       | Cloud AI models       | On-device AI model                              |
| **Storage**             | Mavio cloud           | Local device (optional cloud sync of text only) |

<Tip>
  Privacy mode is ideal for confidential meetings — board discussions, legal conversations, HR matters, medical consultations, and any situation where you need certainty that audio never leaves your machine.
</Tip>

## Enabling privacy mode

### Desktop app

1. Click the Mavio icon in the menu bar (macOS) or system tray (Windows).
2. Click **Privacy mode** to toggle it on.
3. Or use the keyboard shortcut: `Cmd + Shift + L` (macOS) / `Ctrl + Shift + L` (Windows).

### Per-recording

You can enable privacy mode for individual recordings without changing the global setting:

1. Before starting a recording, click the dropdown arrow next to the Record button.
2. Select **Record with privacy mode**.

### Always-on

To make privacy mode the default:

1. Go to **Settings > Recording > Privacy mode**.
2. Toggle **Always use privacy mode** to on.

## First-time setup

Privacy mode requires downloading the on-device AI model:

<Steps>
  <Step title="Enable privacy mode">
    Toggle privacy mode on for the first time.
  </Step>

  <Step title="Download the model">
    Mavio will prompt you to download the on-device transcription model. The download is approximately **1.5 GB**.
  </Step>

  <Step title="Wait for installation">
    The model is installed locally. This takes 2-5 minutes depending on your internet speed and disk performance.
  </Step>

  <Step title="Ready to use">
    Once installed, privacy mode is ready. Future activations are instant — no redownload needed.
  </Step>
</Steps>

<Note>
  The model is stored locally and updated periodically. Updates are downloaded in the background and applied the next time you restart the app.
</Note>

## Accuracy comparison

On-device processing uses smaller, optimized models compared to cloud processing. Here is how accuracy compares:

| Metric                        | Cloud mode            | Privacy mode           |
| ----------------------------- | --------------------- | ---------------------- |
| **English transcription**     | 97-99%                | 94-97%                 |
| **Non-English transcription** | 93-97%                | 88-94%                 |
| **Speaker identification**    | 95-98%                | 85-92%                 |
| **Summary quality**           | High                  | Good                   |
| **Processing speed**          | 2-5 min after meeting | 5-10 min after meeting |

Privacy mode accuracy continues to improve with each model update. For most meetings, the difference is negligible.

## Supported languages in privacy mode

The on-device model supports the following languages:

* **Full support (95%+ accuracy):** English, Spanish, French, German, Portuguese, Italian, Dutch, Japanese, Korean, Mandarin Chinese
* **Good support (90-95%):** Russian, Polish, Turkish, Arabic, Hindi, Swedish, Norwegian, Danish
* **Basic support (85-90%):** Other supported languages

<Warning>
  Some less common languages may have noticeably lower accuracy in privacy mode compared to cloud mode. For these languages, use cloud mode unless confidentiality is essential.
</Warning>

## System requirements

Privacy mode uses local compute resources for AI processing:

| Requirement    | Minimum      | Recommended                                            |
| -------------- | ------------ | ------------------------------------------------------ |
| **CPU**        | 4 cores      | 8+ cores or Apple Silicon                              |
| **RAM**        | 8 GB         | 16 GB                                                  |
| **Disk space** | 2 GB free    | 4 GB free                                              |
| **GPU**        | Not required | Metal (macOS) or CUDA (Windows) accelerates processing |

Apple Silicon Macs (M1 and later) provide the best privacy mode performance thanks to the Neural Engine.

## What data is stored locally

In privacy mode, the following data stays on your device:

* Original audio recording
* Full transcript with speaker labels and timestamps
* AI summary and action items
* Voice profile data for speaker identification

## Optional cloud sync

You can optionally sync text results (transcript, summary, action items) to the Mavio cloud while keeping audio local:

1. Go to **Settings > Recording > Privacy mode > Cloud sync**.
2. Toggle **Sync text to cloud** on.

This lets you access your meeting notes from the web app and mobile app while ensuring the original audio never leaves your device.

<Note>
  When cloud sync is enabled, only the text output is uploaded. The audio file remains exclusively on your local machine. You can delete the cloud copy at any time without affecting the local version.
</Note>
