"Mastermind presents a critical privacy risk profile (78/100) comparable to mainstream ad-supported platforms. The service collects extensive sensitive data including financial information, location, device identifiers, and behavioral activity across platforms, then shares this data broadly with advertising networks, data exchanges, and marketing providers. Multiple enforcement mechanisms severely limit user recourse: mandatory arbitration eliminates lawsuits, fragmented opt-outs require separate actions per device, retention periods are indefinite, and the company reserves unilateral rights to modify policies and deny identity verification requests."
