Personal Results in Guest Mode

While Guest Mode is active, Google Assistant will not provide personal information such as:

• Calendar events
• Personal reminders
• Saved contacts
• Personalized account information

This helps protect private information when multiple people use the same device.

Third-Party Services

Some third-party services connected to Google Assistant may continue to process activity according to their own privacy policies.

Examples may include:

• Music services
• Video services
• Smart home integrations

Users should review privacy settings for connected services separately.

Best Practices

✓ Enable Guest Mode when visitors are present.

✓ Disable Guest Mode when personalized features are needed.

✓ Review privacy settings periodically.

✓ Use Guest Mode on shared household devices.
