Isn’t the whole point of such a service to store your data? To make it possible for others (genetically) related to you, to find you?

  signal does some hash-based matching of your contacts without storing your contacts (but also re 'whole point', not sure about split btwn people who want their own genetic profile vs searching for long-lost twin)

    In order to use DNA tests in genealogy, you need to know every segment on every chromosome that matches. Matching is not a go/nogo proposition. There are degrees of matching that depend on the biological relationship. Ex: Parent/children average 3,700 cM (centiMorgans), siblings are 2,600 cM, first cousins 900 cM etc. See: https://whoareyoumadeof.com/blog/need-a-dna-centimorgan-chart/ https://whoareyoumadeof.com/blog/need-a-dna-centimorgan-char...

      You can do holomorphic encryption.

        The DNA date needs to be readable by third-party apps, if the user so wishes.

          Yes, and that can be done with homomorphic encryption? I don't understand your objection.
