Notice is a work-in-progress. Use at your own risk.

We do our best to preserve the code and documents you develop, but you should regularly back-up your work to another storage system (e.g., using our sftp feature).

Any account that that has not been used in 30 days will be deleted, including all code, documents, sysouts and preserved sessions.

Although the system is reasonably secure, it is not intended to be used for any task where security is important.
