Create a smart-home privacy data map

A privacy map asks what each device senses, where the data is processed, how long it is stored and who can access it.

PrivacyData

Editorial review: August 12, 2026 · Julian M. Carverton

Start with sensors

Cameras, microphones, occupancy, location and environmental sensors collect different kinds of information.

Separate local and cloud processing

A device can use local control while still sending diagnostics or media to the cloud.

Check retention and sharing

Video history, voice history and analytics can have different storage settings.

Review after adding platforms

Multi-ecosystem control can increase the number of accounts and services involved.

Keep in mind. Compatibility is not permanent. Confirm the current manufacturer, platform and certification information before purchasing, resetting or migrating a device.
