Privacy and device management

Managing who can see the feed is a core part of a safe setup. Clear controls prevent accidental sharing and help you adapt as your family grows.

• Limit data sharing. Choose apps that minimize data collection and provide clear privacy options. Review what is being sent to servers and whether it can be stored or accessed by others.
• Manage who can view the feed. Set up viewer accounts with different permissions. For example, designate a primary caregiver as the main viewer and restrict others to limited access if needed.
• Consider guest or restricted viewing options. Some apps let you create temporary access for a caregiver or family member. Rotate permissions after a period of use or when roles change.
• Regularly audit connected devices. Periodically check which devices are linked to your account and remove any that are no longer in use.
• Use privacy controls on the devices themselves. On both Android and iOS, review app permissions, limit location tracking, and disable background activity that isn’t essential for the monitor.
