Nulab Pass has released the new Audit Log feature! 
It is available under the Nulab Pass subscription plan, and works for all Nulab products (i.e. Cacoo, Backlog, Typetalk)
What is Audit Log?
Audit Log is a security feature that helps organizations to better track and safeguard access to their data. Admins and members with the audit log privilege can download a log of activities and events (e.g. logins, new members invited, files downloaded, etc) within their organization in Nulab products.
The log is in the form of a CSV file with dates/times of the events that occurred. Only admins with the audit log privilege can access/download the log, other members or admins cannot access it.
For more info about the Audit Log feature, please see our support guides: Download audit logs, and Audit log settings and file
