## Is E-Stim Connect Secure?

E-Stim Connect is as secure as we can make it. All communications to and from the server are encrypted with SSL connections, with limited and secure access to the server.

All connection keys are generated in a time sensitive random manner, and it's extremely unlikely someone will be able to guess yours, and even if they do, you can disconnect and reconnect to get a new Connection Key, locking out someone you won't want to stim you. Keys only last for 4 hours, so someone obtaining an old key would not be able to use it in any way.

Records of connections to the server are only retained for technical support and do not contain details of commands sent to your E-Stim unit or its responses. Such records only contain the IP of the computer requesting the connection, the key issued, and the version of the software being used to make that connection. No other data is retained.

Commands sent to your E-Stim unit and its responses are never stored on the server, although E-Stim Systems may, with your permission, monitor commands sent and responses received during an active debugging session, but this would only occur with your full knowledge and permission.

We don't store reams of personal information as we consider it a security risk and we don't need it. If we don't have your personal information they we cannot loose it to hackers etc.
