Review a smart speaker as an account-connected device, not merely an appliance. Check who can activate it, what history is retained, which personal results and services it can expose, whether purchases require protection, and how the device will be removed and reset before disposal.
Identify accounts, rooms, and connected services
List each speaker or display by model, room, device name, owner account, household members, Wi-Fi network, linked music or video services, smart-home devices, calendars, contacts, calling features, photos, and third-party skills or actions. Remove services no one uses and confirm that each remaining connection has an accountable owner.
Place extra scrutiny on bedrooms, offices, children's spaces, and displays that show photos or calendar details. Check the physical microphone and camera controls. Explain their purpose to everyone who shares the space so a privacy setting is not silently undone.
Review voice history and retention
Open the provider's privacy dashboard and inspect recent entries, including unexpected activations. Amazon's Alexa device FAQ says users can review and delete associated voice recordings, text transcripts, and typed requests through Alexa Privacy settings. It also cautions that data held by third-party skill developers or stored outside Amazon's cloud may not be deleted by that action.
Choose the retention setting that matches the household's needs and recheck it after major account or assistant updates. Deleting history may affect personalization or features, so document the tradeoff. Review third-party service histories separately when those providers retain activity.
Limit personal results, guests, and purchases
Decide whether the device should announce calendar events, read contacts, display photos, place calls, or access individual services. Turn off personal results on devices in shared areas when the convenience is not worth the exposure. Use voice recognition only as an added control, not as the sole protection for a sensitive action.
Google's Guest Mode guidance says assistant activity and audio recordings are not saved to the device owner's account while Guest Mode is active, and personal results are withheld. It also notes that interactions with other services may still be stored by those providers. Tell guests how the device works and enable the appropriate guest or restricted mode before they use it.
Review voice-purchase settings even if no one remembers enabling them. Amazon's shopping guidance for Alexa describes purchase controls that can require a code or allow only recognized voices. Disable voice purchasing when it is unnecessary; otherwise require the strongest available confirmation and protect the code from being spoken or displayed near the device. Review recent orders and payment methods after changing the setting.
Check microphones, alerts, and household changes
Test the microphone mute control and verify its indicator. Review drop-in, intercom, calling, announcement, emergency, and remote-access features. Remove former household members and old phones from the account. Change passwords and revoke sessions when someone who had account access leaves the household.
Repeat the review after moving the device, adding a camera display, linking a new service, or changing family access. A kitchen speaker and a private-office display do not need identical settings.
Prepare a device for sale, donation, or recycling
Remove the device from linked homes and services, preserve any needed clips or settings, and follow the exact model's reset procedure. Google's factory-reset guide states that a factory reset clears device data, disconnects the device from home members, and cannot be undone; it also provides model-specific physical-button steps.
After the reset, confirm the device shows the initial setup state and no longer appears as active in the owner account. Remove it from trusted-device and payment lists, delete unneeded cloud history separately, and record the serial number and disposal date. Use an approved electronics recycler for a device that will not be reused. A factory reset, account cleanup, and cloud-history review are separate checks, and all three may be needed for a complete handoff.
