Families are increasingly using new apps and devices that provide detailed information about the location and activities of children and other family members. While typically performed for benevolent reasons such as maintaining child safety, tracking technologies like Life360 and Find My iPhone raise concerns about snooping and surveillance. This paper examines parental behaviours and attitudes towards this controversial practice via an online survey that collected 112 responses from parents of children aged 5–18. A significant number of parents reported using tracking tools. Parents’ views about the practice were sometimes ambivalent and in disagreement. Perspectives variously included: defending geo-tracking as conducive to child wellbeing and family management and logistics, contesting the language of surveillance used to describe it, and opposing the use of these technologies as antithetical to child independence and choice. After exploring such themes, the paper identifies and critically discusses the socio-ethical issues of changing family norms associated with powerful child monitoring technology, child autonomy and consent, and the normalisation of geo-tracking and surveillance. The discussion employs Helen Nissenbaum’s (2009) concept of contextual integrity to evaluate family and child privacy and to illuminate the socio-ethical complexity of this evolving technological practice.
