# 🔒 Ephemeral Mode: Full Privacy, Even Internally

> Ephemeral Mode lets users start private, temporary sessions where no content is stored or visible to admins. It’s designed to prevent shadow AI and ensure full privacy, even internally.

### Context

Our solution is already deployed **on-premise**, with **full protection from external exposure**: no data is ever sent outside or used for training. But another key concern remains: *****how can we reassure users about their internal privacy?*****

Many employees hesitate to use AI for sensitive or exploratory conversations, fearing that their content could be seen by admins or managers. This hesitation fuels the rise of **shadow AI**, where employees turn to unsanctioned tools that compromise security and governance.

### The answer: Ephemeral Mode

With **Ephemeral Mode**, we provide complete privacy even internally:

* **100% private and ephemeral sessions**: no messages, document links, or feedback are stored.
* **Total invisibility to admins**: even system administrators cannot access the content.
* **Automatic deletion** after 15 minutes of inactivity.

This gives employees the confidence to ask questions, test ideas, or handle sensitive data without leaving any trace behind.

### Governance and activation

* Controlled at the **instance level** by the System Admin.
* If the feature is enabled at the instance level, a **Company Admin** can then activate it for their company.
* Once enabled, users can start a private session directly from the interface with a simple toggle.

⚠️ This feature should be used with caution in contexts where **traceability** is required.

### User experience

* A clear banner indicates when a session is ephemeral.
* On exit, users are warned that all content will be lost unless copied.
* Available actions are adjusted:
  * 🚫 **Bug reporting is disabled** (sessions are anonymous and short-lived).
  * ✅ **Copy and share** remain available so users can reuse content if needed.

### Key benefits

* 🛡️ **Double privacy**: external (on-prem, full privacy) and internal (invisible to admins).
* 🚫 **End of shadow AI**: no need to look elsewhere — sensitive work can be done safely within the official tool.
* 🔄 **Better adoption**: employees feel confident to explore and use AI without fear.

### Conclusion

With **Ephemeral Mode**, we go one step further: after guaranteeing **external confidentiality**, we now deliver **internal confidentiality** as well.\
The promise is simple: *your employees can trust the official tool, because their conversations belong to them — and only to them.*
