Splashtop maintains logs for self auditing. There are 3 different sets of logs: "Sessions", "File Transfers", and "History". Login to my.splashtop.com, then click on the "Logs" tab/menu.
The session logs can show the last 7, 30, or 60 days of connection logs. These logs include names and IP addresses of the 2 devices, time, user, and duration of the connections. If your service includes both unattended and attended access, you can choose which logs to view.
If you scroll to the bottom of the page, you can download up to a year of logs in CSV format, "Export as CSV".
Any file transfers during the remote session will be logged under this section. The logs include the names of the files transferred, but do not include any content.
These history logs show administrative actions, such as computers added/removed, group settings, permissions, etc. The logs note the time, account, IP address, and action. These logs are not exportable, but you can view the full history.
