Higher Regional Court of Hamm on WhatsApp Address Books: Warning Trap in Automatic Contact Sync

Faits validés

Whoever installs WhatsApp on a smartphone and consents to address-book access transmits contact data of uninvolved third parties to servers in the USA unsolicited. Without the contacts' consent, this constitutes a legal violation.

En termes simples

Betrayal in the circle of friends: Your phone reveals grandma's number to a US corporation even though grandma has never owned a smartphone.

Pertinence sécurité & conseil pratique

Especially relevant for work smartphones: Without MDM (Mobile Device Management) and separation of contacts, labor and data-protection warnings loom.
