This software does not have access to your email nor your email account. This program does not spam, spim, nor spat. The source code is freely available for all to look at. That is the nature of Sherlock programs. the Javascript is sent to Sherlock in real time, without any downloads.
The Sherlock program is SUPPOSED to open. This is a Sherlock plug-in does. The "scary warning" is the warning that Apple displays for all non-Apple Sherlock Channels: "This is a non-Apple channel."
Lastly, this is a Sherlock Channel. There is nothing to download! Sherlock opens the application through URLs. The "download" button sends the channel URL to Sherlock, and it opens it (with such a benign warning as: "This is a non-Apple Channel").
Please do not be put off by comments that display a lack of knowledge of what Sherlock is and does. From the source code you'll find that there is nothing scary about this program. It just does what is described.
