Deadmanswitch™ lets you create an encrypted “package” on your device that is then uploaded and stored securely in the cloud. A package consists of a recipient email address, a message, attachments, and a passphrase hint. Delivery of your package occurs when there is no detection of user presence. Your recipient is contacted by email and given a unique link and your passphrase hint. They can download your package through an ordinary web browser. Detection is determined by step data and email confirmation. As long as you’re moving, you’re considered “present”. If no movement is detected, we’ll email you to confirm. If there’s no response, your package will be delivered.
