SSD works differently than other projects do. Since their goal is to help prevent your data from being taken by others, they themselves do not accumulate data. Their project does not provide any data, instead they provide ways to protect data. SSD does not have any data inputs or sources, nor does it have any to share. Their end results, however, are to make sure they provide the best ways to protect data.
When it comes to best practices and data, SSD excels. The data for their project is technically your own, as that is what they want to protect. They do not retrieve, compile, or create any data themselves. Because SSD does not directly use any data, there are absolutely zero privacy, security, or legal issues.
