We maintain the key and will never share it without your consent. The key is critical to reporting microbiome data back to the correct person. Additionally, maintaining these identifiers will be crucial when we plan to add additional health features to our platform such as dental consults, tracking the outcomes of therapeutic/preventative interventions, and improvement tracking.
Of course, there are a few tricky circumstances around the future of the data. What happens if we go bankrupt/sell the company? I can't say for sure what will happen, but I am fully committed to the destruction of the key at any point when we realize that the identifiers do not serve a purpose.
The statement is meaningless if you have the key.
