What Stillis processes
When you use Stillis, it processes:
- Your voice — converted into acoustic metrics (energy, rhythm, stability, tone). The audio itself is never stored.
- Your conversations — the text of what you say and what Stillis responds.
- Optionally, expression and physiological signals from your camera — converted into behavioral and thermal indicators. No video is recorded or stored.
What stays on your device
Everything. All personal data lives in local files on your machine:
- Conversation history
- Voice metrics and patterns
- Long-term memory
- Personal baseline
Nothing is uploaded to any server. Nothing is synchronized to any cloud.
What may leave your device
When you send a message, the text is sent to a language model API — Claude by Anthropic, GPT-4 by OpenAI, or Gemini by Google — to generate a response. This is the only external communication Stillis makes.
No audio is sent. No biometrics are sent. No personal profile is sent.
What Stillis does not do
- Does not sell your data.
- Does not build advertising profiles.
- Does not share data with third parties.
- Does not record video.
- Does not store raw audio beyond the session.
Your control
You can delete your conversation history at any time. You can remove the application and all its data completely. Stillis does not retain anything after uninstallation.
FAQ

Does it store my voice?
No. Voice is processed into irreversible metrics. The audio is not kept.
Can I delete my data?
Yes. From within the application at any time.
Is the camera always active?
No. The camera activates only during active sessions, and only if you have not disabled it.
Does it need internet?
For conversation — yes, to reach the language model API. For everything else — no.
Who can see my data?
Only you. No one at Stillis has access to your local data.
What happens if I uninstall?
All local data is removed with the application.
