Does the Toolbar store any sensitive data locally?

The Toolbar stores some access data locally on your computer. This encrypted cached data consists of information retrieved about secure messages. It is used by the Toolbar for two primary reasons:

  1. To support offline mode. Without cached information, secure messages would display incorrectly in offline mode.
  2. To make secure message loading more efficient. Even when the client is not working in offline mode, it is inefficient to retrieve static data every time a message is selected. The encrypted local cache takes a portion of the load off the server database.

The data that is stored in your local environment is non-sensitive, and encrypted regardless. The cache is reported as invalid if it has been tampered with in any way.
