WhatsApp Adds Restricted Chat Feature to Keep Conversations on Primary Phone Only
What Happened — WhatsApp’s Android beta (v2.26.36.5) introduces Restricted Chat, a per‑chat setting that stops a selected conversation from syncing to any linked devices (WhatsApp Web, secondary phones). When enabled, the chat remains only on the primary mobile device and cannot be exported or processed by Meta AI.
Why It Matters for Trust & Control Assurance
- Demonstrates an access‑control safeguard that limits data exposure to authorized endpoints only.
- Provides a concrete control that can be logged and presented as evidence in continuous‑monitoring programs.
- Reduces the attack surface where modified web clients or AI agents could harvest messages from linked sessions.
Who Is Affected
- Messaging platform providers and their enterprise customers.
- Organizations that rely on WhatsApp for business communications, especially those handling confidential or regulated data.
Recommended Actions
- When the feature becomes generally available, enable Restricted Chat for any conversation containing sensitive information.
- Update device‑access policies to reflect the new control and capture configuration screenshots for audit evidence.
- Incorporate the setting into your continuous control‑assurance dashboard to demonstrate ongoing compliance.

Technical Notes
- Feature is currently in Android beta; not yet visible to all users.
- Works by preventing the chat’s message store from being replicated to linked devices, including WhatsApp Web sessions.
- Does not affect existing protections such as media‑auto‑save blocking or export restrictions.
