Is my Elvie workout data stored securely and kept confidential?

When you use Elvie, it sends data from your workouts to your phone. That data is then sent encrypted (using TLS) and stored on our servers on encrypted disks (otherwise it would take up too much space on your phone). To ensure that workout data remains anonymous, we separate it from any personally identifiable data, such as your name and email address, and store it on different servers. We use anonymised data so we can see trends and meet the needs of our users by constantly updating and improving their Elvie experience. Creating an account and sending the data to the servers means that if you lose or upgrade your phone or tablet, you can take your workout history with you. It also lets you use Elvie with more than one phone or tablet. Some of our users prefer to log out after they've used Elvie so no one who accesses their phone or tablet can access their data.
