DMS is a safety, security, and secrecy application used to delivery a encrypted "package" in the event of your absence.
Who it's for:
- ordinary person planning for the unexpected
- military person or person in a state of war
- person in poor health wishing to delivery an "emotional will"
- adventure seeker undertaking extreme challenges
- professional journalist working in dangerous environment
- activist protestor exercising rights against injustice
- crypto bro that self-custodies their digital fortune
- solo dweller, traveller, or hermit living alone
- pirate with a treasure chest full of gold
How it works:
- the app is used to create a "package" on your device that is then uploaded and stored securely in the cloud*
- detection of your presence is determined by Steps, Email, or SMS†
- in the event of your absence, your recipient(s) will be contacted by email and your "package" will be delivered
What ifs:
- if you enable Steps but don't step, you'll be prompted with a notification before you are sent an email
- if you lose your phone or delete the app, you'll be sent an email to confirm your presence
- if you are captured, you can configure your detection schedule beyond 4 weeks
Delivery:
- this app is really about the recipient, not the user
- in the event of your absence, our compliance team will review and reach out to you before delivery occurs
- when delivery occurs, your recipient(s) will be notified and given their "package"
- recipient delivery is easy enough for your grandma to understand
