Hey pikecara! This is a very good question. We believe that security is key for our users and therefore we believe we got one of the best security experts we could find as our advisor: Hainan Hu, formerly Zalando and Sound Cloud, now Boston Consulting Group Digital Ventures: https://www.linkedin.com/in/hainan/. One of the data storage solutions we are looking at are HIPPA compliant AWS services. The other solution is developed by the former company of our advisor Dr. David Manset, Gnubila: https://www.fedehr.com/. Now, both FedEHR and HIPPA compliant AWS services are meant to be protecting electronic medical records. The information Lympo will be working with, the data from health and sports tracking apps, is not qualified to be as sensitive as medical health records, but we still prefer to use one of these solutions to make sure that in the future our users could store their medical records as well.
