Why is the HAT unique

You will legally own the HAT database and the database rights, and only you give the rights to the data within it - no one else. You are the data controller and the data subject. You can legally request for data to be pulled into your HAT, as part of a subject access request to companies that hold your data. Since ownership is given to you, it can be treated as part of your estate.

If you are a minor, your HAT would be managed by your legal guardian or trustee. Also, a HAT provider is your agent; they do not have any rights to access or view the contents of your database.

The HAT Community Foundation regulates the HAT data exchange system operated by HATDeX, the concierge for the data, delivering data between HATs and HAT-enabled organizations, upon instructions.
