A private, personal system for one person's life admin.
LifeOS runs on its owner's own computer. It keeps track of that person's bills, bookings, deliveries, renewals and reminders, and it is used by nobody else. It is not a product or a service, and there is nothing here to sign up for.
LifeOS asks its owner for permission to read their own Gmail, so that what arrives by email reaches their records without retyping. It only reads. It does not send, change or delete email.
