Abstract. Domestic violence within the home is a critical societal issue with severe physical and psychological impacts. Research shows that children often do not disclose their abuse, making it challenging for adults to offer help. In Sweden, over 200,000 children live in households affected by various forms of violence, prompting the Swedish government to allocate over SEK 600 million in 2024 to combat domestic violence. Exposure to domestic violence often results in betrayal trauma, which can result in a child's ability to trust others. This study addresses this gap by using a Research through Design (RtD) methodology to inform the development of digital helper applications for children. The RtD process involved four phases: (1) Background Research, (2) Prototype Development, (3) Prototype Testing, and (4) Integration of New Insights and Prototype Refinement. Empirical data was gathered through three workshops with 21 participants, leading to the creation of a prototype named My Safe Place. The study identified five key design insights, (1) Anonymity and Privacy, (2) Accessibility and Usability (3), Clarity of Functionality (4), Educational Content (5) Design Adaptability. 

D Digital Support Services. These insights aim to improve the design of digital support tools for children experiencing domestic violence within the home.
