Stymie is an anonymous harm reporting tool that schools are proactively using to support their students to say something without fear. We work with school communities both nationally and internationally, to connect students with their empathy and conscience so that they can, in an empowered and courageous way, enhance or change the culture of care in their school.The notification interface allows bystanders to upload evidence like screen shots of nasty, aggressive, risky or harmful social media interactions and a detailed outline of the incident(s).The notifications are encrypted, anonymous and confidential. Stymie does not have access to schools’ information or statistics.Stymie has been built to support existing student well-being/pastoral care frameworks in schools and was built in consideration of the Australian Student Wellbeing Framework and the recommendations from the Australian Covert Bullying Prevalence Study.
