At Posifon we value the personal integrity and the ability for the user to keep his or hers independence and freedom despite a changed life situation or health issues. Based on these grounds of values we have developed a flexible service to suit a number of different needs. Today we offer the only scientifically evaluated GPS based safety alarms in Sweden. A high IT security is a matter of course and the use of the service is being logged. As the only supplier in Sweden we have created ethical guidelines for the use of mobile safety alarms. We have done this in cooperation with leading scientists and you can read more about these guidelines in our bank of knowledge as well as in an internationally published scientific study where our services and GPS alarms have been evaluated.
