Where is my child's Halo Lytt data stored?

On secure servers in Ireland, under EU data protection law. It is encrypted in transit and at rest, visible only to you through your parent account, and never sold or shared with advertisers.

Storing children's health data inside the EU means it falls under the General Data Protection Regulation, which sets specific obligations around consent, data minimisation, the right of access and the right to erasure. Children's data receives additional protection under GDPR.

That is a meaningful distinction for a device measuring a child's biometrics. Full detail on our data and security page.
