If you live in the UK, and would rather your medical information were not stored in a central database (no, not the Summary Care Record database, yet another central database) and given, in a possibly-anonymized-but-no-guarantees form, to researchers and companies, then you need to actively opt out. Yes, really.

See medconfidential.org for how to do it.
