The one you link to doesn't really make sense:
> Data is collected on specific sites that the product is not working on. This data is sent explicitly by users and when it is collected we do not collect any information that could be tied to a specific user. Only the name of the site is collected and any additional information you include in the text of the report.
The original one that was deleted from the Github repo [0] is much simpler and to the point.
