Privacy in the Nursery

Baby monitor apps sit in the middle of family life. That is why data minimization matters.

Children Have Rights — Digital Ones Too

The General Data Protection Regulation (GDPR) gives children's personal data special protection. Article 8 and Recital 38 say, in plain terms, that children are less able to judge risks and consequences. For parents, that means an app in the nursery deserves more scrutiny than a weather widget.

In reality, privacy in baby monitor apps is often handled in small print. Sometimes it even feels like part of the business model.

What Typical Baby Monitor Apps Collect

A look at the Baby Monitor Timmy privacy policy and policies from other baby monitor apps quickly shows which data commonly appears:

All of this data comes from the most sensitive place there is: your child's bedroom. In many cases, it lands on servers you do not control.

How Timmy Does It Differently

Baby Monitor Timmy was built from the start around data minimization. In GDPR terms, that means collecting only the data needed for the specific purpose. Not everything that is technically possible.

In practice, this means:

Firebase: Only the Essentials

Timmy uses Firebase for signaling, meaning coordination of connection setup between baby and parent device. Firestore receives technical data such as SDP offers (Session Description Protocol) and ICE candidates for WebRTC. They contain no personal information and become invalid after a short time.

Audio streams, video data, and usage profiles do not belong in Firebase. The actual communication runs directly between the devices and is encrypted by WebRTC.

Data Minimization in Practice

Data minimization is not something you add at the end as a checkbox. It sits in the architecture. For Timmy, it means:

What we don't collect, we can't lose. What we don't store, can't be hacked. What we don't know, can't be misused.

For every feature I ask the same question: can this work without collecting more data? So far in Timmy, the answer has been yes.

Conclusion: Privacy is Respect

Privacy in the nursery is more than a legal duty. It is respect for your child. Your baby cannot decide what data is created about them. That responsibility sits with you and with the apps you let in.

Baby Monitor Timmy takes that responsibility seriously. Nice promises are not enough for me; the architecture should avoid collecting data that is not needed for baby monitor operation in the first place.
