case of emergency, and have a night ride service so that no one has to walk alone. Callisto's biggest competitor is Lighthouse. Callisto's approach is sensitive to trauma when reporting. A Callisto phone app was discontinued so that people could not be embarrassed by having it; the service is available only online, and is confidential. Callisto believes that there is safety in numbers. Criticism Since the data collected from Callisto is stored on a database by a third party, critics are worried that this information could potentially be hacked and the victims identities revealed despite the heavy bank like security and encryption that even Callisto doesn't have access to. Survivors enter identifying details of their assailant, such as social media handle or phone number (encryption keeps the identities of the survivor and the perpetrator anonymous, not identifiable even if the database is hacked).
