Baby monitor privacy: one night's video, followed from the crib through 13 makers' policies

Where does the baby's video go tonight?

Down one of three roads. A radio monitor sends the picture across the house to its parent unit and nowhere else. Infant Optics says it plainly: "There is no IP address involved. There is no route to the internet" (Infant Optics).

A cloud monitor sends the picture to the maker first. Nanit calls it a feature: your stream "can only be pushed by Nanit's secure servers to your mobile device", and video is stored only "if you've opted into a Nanit Insights Plan" (Nanit). The live view of your crib passes through a company, plan or no plan.

A phone app on your Wi-Fi takes the third road. Cloud Baby Monitor "uses by default only your home WiFi network to transmit live audio and video between the devices. No internet connection is required" (Cloud Baby Monitor's FAQ). The picture goes from the phone by the crib to your phone through your own router, and that is the whole trip.

The monitors sorted by the road their maker describes. Owlet, eufy and Annie are missing: their policies do not say.

Who keeps the video, and for how long?

Once the picture reaches a server, how long does it stay? The makers answer in days, tied to plans: Nanit's Memories subscribers "can view up to 2 days of past full Video History", Milestones subscribers "up to 7 full days" (Nanit memberships).

Monitor	Video on the maker's side	Kept for	Its words
Nanit	yes, live and history	2 or 7 days, on a paid plan	"up to 2 days of past full Video History" (Nanit)
Miku	yes	3 days, longer for a fee	"3-Days of Activity Video Storage" (Miku)
CuboAi	yes, on Google Cloud	7 days for event thumbnails	"upload the recorded audio and video data to Google Cloud" (CuboAi)
Owlet	clips	14 days, on a paid plan	"14 days of history saved in your Owlet Dream App" (Owlet360)
VTech (Wi-Fi models)	yes	until the plan ends or storage is full	"transmitted to the servers of VTech or its service providers" (VTech)
Bibino	yes	21 days, on Premium	"audio and video recordings, photos … are stored for 21 days" (Bibino)
Baby Monitor 3G	away from home only	nothing kept	"the communication has to run through our server", end-to-end encrypted (TappyTaps)
Dormi	relay when needed	nothing kept	"no recordings stored in the cloud" (Dormi)
Cloud Baby Monitor	no, by default	nothing kept	"uses by default only your home WiFi network" (Cloud Baby Monitor)
Mamoon (ours)	no	nothing kept	picture and sound stay on your home Wi-Fi (Mamoon's policy)

From the policies and plan pages linked in each row, read November 6, 2026. eufy and Annie do not say; Infant Optics and HelloBaby have no app to keep anything.

The apps that work over your Wi-Fi mostly have nothing to keep. The whole picture, five questions per monitor:

Video via servers

Does the baby's picture go through the maker's servers? away: only while you watch from outside the home. relay: an end-to-end encrypted relay when the phones cannot link directly. clips: recorded clips; the policy is silent on live video. ?: the policy does not say.

Account

Must you create an account before you see the picture? Prem.: Bibino Premium only. opt.: optional, for one extra mode.

Ads

Does the policy share data for advertising? may: it says the sharing may count as a "sale". some: ad tracking events go to Meta. store: the maker's web store only; the monitor has no app.

AI

May the maker train AI on your data? may: the policy allows it. asked: owners were asked to donate videos. –: the policy says nothing. n/a: no app, no data.

Trackers

Outside services the homepage loaded from an EU address before any cookie choice, November 6, 2026. –: store unavailable that day.

Who may train AI on your baby's recordings?

Two makers write it down. CuboAi: "The recordings will also be used to train CuboAi's algorithm to become increasingly better at recognizing dangerous situations for infants". Its legal basis is "legitimate interest", not your consent. Objecting "may prevent you from continuing to use our service and products" (CuboAi). Your nights are the training set.

Owlet's policy, updated July 2026, says it may use your data "to develop and train artificial intelligence and machine learning models" and may "collaborate with trusted research partners" (Owlet). Its sock measures pulse and oxygen, so this is your baby's health data.

eufy took a third route: it asked. In 2025 it paid owners of its security cameras for videos to train its AI. It "also asks users to donate videos recorded with the company's baby monitors" (TechCrunch, October 1, 2025). A request you can decline is one thing; training on every recording by default, as CuboAi's policy allows, is another.

Who shares your details with advertisers?

By the time the baby is asleep again, the data has a second life. Nanit's policy says: "We do share information with third parties for the purpose of cross-context behavioral advertising or targeted advertising" (Nanit). Miku hands identifiers and web activity to "advertising networks" (Miku). VTech may pass tracking data "with our business partners and advertisers" (VTech). eufy concedes that its ad disclosures "may qualify as the sale of Personal Data" under US state law (eufy).

The phone apps play the same game on a smaller scale. Bibino's free version shows ads, and its policy names AdMob and Facebook remarketing (Bibino). Annie shows none. It does tell Meta when you install, start a trial or subscribe, to "improve our advertising campaigns on Meta platforms" (Annie). Dormi's website promises "zero ads, ever" (Dormi). None of this touches the video; it shows what the maker does with the parent.

What happens before you even buy?

The website starts collecting first. Each homepage was opened once from an EU address, no cookie banner touched, and the outside services it loaded in about 11 seconds were counted (from the browser's own list).

Nanit's homepage loaded 34 outside services, Meta's ad tracker and Microsoft Clarity among them; Dormi's loaded none (what Clarity records). Even a monitor with no app has a store: Infant Optics' homepage set Meta's cookie before any banner appeared. A tracker never sees the crib, but it shows how a company treats you before you have paid.

Can you trust the store labels?

Only as far as the maker filled them in. Both stores make an app declare what it collects and shares, and neither audits the form (Google's Data safety help).

Same app, two stores, different answers.

App	Play: shared	Apple: tracking	Apple: own ads	Stores
Bibino	"No data shared"	Usage Data	none listed	disagree
Nanit	name, user IDs, app use, for "Advertising or marketing"	none	none listed	disagree
Miku	"No data shared"	none	name, e-mail, app use	consistent; its own ads only
Owlet	"No data shared"	none	rough location	consistent; its own ads only
Annie	app use and device IDs, for analytics	none	none linked	consistent
CuboAi	"No data shared"	none	none listed	consistent

Three lines from each store, read November 6, 2026: data Google Play lists as shared with other companies; the App Store's "Data Used to Track You"; App Store data linked to you for the maker's own advertising. "Disagree" marks a row where the two forms contradict each other.

Bibino shares nothing on Play but tracks on Apple, where tracking means following you across "apps and websites owned by other companies" (Bibino on the App Store). Nanit shares for advertising on Play but lists no tracking and no advertising purpose on Apple. Both labels are self-declared. And Google's "shared" excludes the companies a maker pays to process data for it, so "No data shared" can sit beside analytics or ad tools in the app (Google's definition).

Check your own monitor in two minutes

1. Google Play: find "Data safety" on the app's page and tap "See details". Read "Data shared" first, then look under "Data collected" for "Advertising or marketing".Each kind of data, its purpose, and whether it is optional.
2. App Store: find "App Privacy" on the app's page. The first box, "Data Used to Track You", is the one to read.Empty is the best answer that box can give.
3. The privacy policy: open it and search for train, advertising, sale and retain.The hits: AI training, advertisers, how long video is kept.
4. Setup: if the app wants an e-mail before showing a picture, the stream likely goes through the maker's servers.No account usually means the picture stays home.

Our verdict on each monitor

Our assessment, from the facts above, applied the same way to every monitor. Five concerns count: video through the maker's servers; AI training allowed, or videos asked for; data shared for advertising; store labels that disagree; an ad tracker before you accepted cookies. None is Best, one Good, two Mixed, three or more Poor.

• NanitPoorLive view only through its servers (road). Shares "for the purpose of cross-context behavioral advertising" (ads). Play and App Store forms disagree (labels). 34 services before consent (trackers) (policy).
• MikuPoorVideo on its servers, "3-Days of Activity Video Storage" (retention). Identifiers go to "advertising networks" (ads). Meta's ad tracker on the homepage (trackers) (policy).
• CuboAiPoorRecordings on Google Cloud (retention), "used to train CuboAi's algorithm" without consent (AI). No ad sharing in the policy. Meta's ad tracker on the homepage (trackers) (policy).
• OwletMixedPolicy silent on the video. May "develop and train artificial intelligence and machine learning models" (AI). Ad disclosures may count as "sharing" (ads). No ad tracker seen (trackers) (policy).
• eufyPoorDoes not say where baby-monitor video goes. Asked owners to donate videos for AI (AI). Disclosures "may qualify as the sale of Personal Data" (ads). Meta, Google and Reddit trackers before consent (trackers) (policy).
• VTechMixedVideo "transmitted to the servers of VTech or its service providers" (retention). May share with "business partners and advertisers" (ads). No ad tracker seen (trackers) (policy).
• BibinoPoor"The communication goes through our servers", 21 days kept on Premium (retention). Ads in the free version (ads). "No data shared" on Play, "Used to Track You" on Apple (labels) (policy).
• Baby Monitor 3GGoodAt home the stream stays between the phones; away it "has to run through our server", encrypted, nothing kept (retention). No account. Its app policy lists Meta's ad tracking (ads) (policy).
• AnnieGoodNo ads, pairing by code. The policy does not say whether the stream is relayed (road). Sends install and subscription events to Meta (ads) (policy).
• Cloud Baby MonitorBest"Uses by default only your home WiFi network"; the internet only in its optional long-range mode (road). No ads, nothing kept. One outside service on the homepage (trackers) (policy).
• DormiBestDirect link, or an end-to-end encrypted relay with "no recordings stored in the cloud" (retention). No account, "zero ads, ever" (ads). Nothing loaded on its homepage (trackers) (policy).
• Infant OpticsGoodNo app, "no route to the internet" (road). Its web store runs personalised ads and set Meta's cookie with no banner shown (trackers) (policy).
• HelloBabyGoodNo app and no Wi-Fi, so no video leaves the house (road). Its web store says it has "sold" and "shared" buyer data with marketing partners (ads) (policy).
• MamoonOursWe might be biased: Mamoon is ours. Privacy is why it exists. Picture and sound go over your home Wi-Fi, not the internet. No account, no ads, no homepage trackers. One catch: anonymous usage counts, unless switched off in Settings.

Where Mamoon fits

Mamoon takes the third road: an old phone or a Wi-Fi camera is the camera, your phone the screen. It keeps working when the internet is down. It keeps no video history, and remote viewing needs your own Tailscale. Everything between the phone at the crib and the parent phones travels encrypted, and the parent phone checks it is the same crib phone it paired with.

The limits: anonymous usage counts go out unless you switch them off, and watching from away needs your own Tailscale. Sound and cry alerts are free; the picture is $29.99 once or $3.99 a month after 14 days free.
