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:

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.

​
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:
1

Enable privacy mode

Toggle privacy mode on for the first time.
2

Download the model

Mavio will prompt you to download the on-device transcription model. The download is approximately 1.5 GB.
3

Wait for installation

The model is installed locally. This takes 2-5 minutes depending on your internet speed and disk performance.
4

Ready to use

Once installed, privacy mode is ready. Future activations are instant — no redownload needed.
The model is stored locally and updated periodically. Updates are downloaded in the background and applied the next time you restart the app.

Accuracy comparison

On-device processing uses smaller, optimized models compared to cloud processing. Here is how accuracy compares:
MetricCloud modePrivacy mode
English transcription97-99%94-97%
Non-English transcription93-97%88-94%
Speaker identification95-98%85-92%
Summary qualityHighGood
Processing speed2-5 min after meeting5-10 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
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.

​
System requirements

Privacy mode uses local compute resources for AI processing:
RequirementMinimumRecommended
CPU4 cores8+ cores or Apple Silicon
RAM8 GB16 GB
Disk space2 GB free4 GB free
GPUNot requiredMetal (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.
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.
