At ECHO, we prioritize your safety. Reach out with any questions about our privacy-preserving safety systems, and our team will provide prompt assistance.
Our Philosophy
We believe schools should be places of learning and growth—free from harassment, fear, and unnecessary surveillance.
Having witnessed the real impact of bullying and the growing mental health crisis among students, we set out to build a safety system that protects individuals without violating their dignity. ECHO reflects our shared belief that effective safety should never require constant monitoring or loss of privacy.
Our Story
We came together after witnessing a situation that revealed a serious gap in school safety. A close mutual friend was repeatedly bullied and physically harmed, yet the incidents went unnoticed because they occurred in spaces where cameras and recording were not allowed. No one intervened until visible injuries appeared. That experience made it clear that the problem was not a lack of concern, but a lack of ethical tools capable of protecting students in sensitive environments.
The Gap We Saw
Blind Spots
High-risk spaces where surveillance is prohibited
Delayed intervention
Victims often don’t report until harm escalates
Privacy tradeoff
Existing systems force safety vs dignity
