SafeToNet, an international company specializing in digital technology and security, describes smart devices for children as gateways to a Digital Dystopia that disrupts their development and fuels cycles of lifelong harm. Marsh and colleagues (2015) also reported that fifty percent of preschool-aged children in the UK have access to four to ten smart devices simultaneously in their daily lives. Such statements, along with numerous similar findings, indicate that the internet safety warning for children and adolescents has been issued seriously through multiple global channels for over a decade, driven by the explosive growth and expansion of social platforms, prompting countries to design and implement frameworks for age-appropriateness of the internet. This research adopts a multifaceted, opportunity-creating, and creativity-inspiring perspective that is simultaneously risk-mitigating. By employing a qualitative approach—combining interview techniques and participant observation—this study primarily seeks to highlight the necessity of appropriating social platforms and the internet on the subjective beliefs, objective actions, personal opinions, and individual preferences of children and adolescents themselves and subsequently, present a categorization of prominent models at both global and local levels.

Five themes extracted from the interview texts—“Accelerated Accessibility,” “Digital Negligence,” “Overestimated Online Safety,” “Anthropomorphizing Technology: The Trusted Omniscient,” and “Childhood Foundations, Mature Preferences”—collectively highlight the significance of the research topic. Furthermore, the threefold classification of “Designing Dedicated Platforms,” “Optimizing Local Platforms,” and “Formulating Strict Regulations and Regulatory Policies” —constitutes the core recognized models of Age- Appropriation Design. Specific cases for each model are detailed within the study.
