Privacy & security
What stays on your Mac.
No account, no ads, no training on your data. Here is how it splits:
Stays on your Mac
- Your chats and memories – stored only on your Mac.
- Answers in local mode – computed on your Mac.
- Knowledge packs and files you choose to share with it.
Goes online – only in these cases
- In online mode: requests to web search – only when you switch it on.
- Downloads of AI models, knowledge packs and updates. No chat content is sent; as with any download, the server sees your IP address.
- No ad trackers on this website.
For this website, see the privacy policy.
The Privacy Center in the app.
The privacy meter counts every connection Chiusora opens itself. In local mode, Chiusora sends no chat content.
How it compares.
Chiusora next to a typical cloud AI chat. Factual, without marketing promises.
| Feature |  Chiusora | Typical cloud AI chat |
|---|---|---|
| Where answers are computed | In local mode, on your Mac | On the provider’s servers |
| Where chats and memories are stored | Only on your Mac | Usually in your account with the provider |
| Chat runs locally | Yes, in local mode | No |
| Account required | No account needed | Usually yes |
| Memories with source and date | Yes, with every answer | Depends on the provider, often not visible |
| Voice mode | Simple voice mode in your Mac’s voice, speech recognition on your device. A more natural voice of its own is in the works | Usually via the provider’s servers |
| Model size | Local: Chiusora Standard | Very large models |
General comparison; individual providers differ. Large cloud models are stronger at many tasks.
