Disclosure: I work at Google Cloud on Kubeflow I can't speak for Netflix's privacy policy, but, if your concern is with Google, we never ever ever ever mix/merge Google customer data with customer data. Like ever ever ever. FWIW, we STRONGLY suggest (just to be doubly sure) that you encrypt at rest and/or offer the option to use Customer Supplied Keys. Encrypt all the things! https://cloud.google.com/security/encryption-at-rest/ https://cloud.google.com/security/encryption-at-rest/
