Modern mobile operating systems such as Android and iOS maintain activity logs that can be disabled, modified, or erased by users or attackers. While this design supports user autonomy, it creates a forensic vulnerability : sophisticated adversaries can eliminate traces of compromise, thereby undermining incident response and digital accountability. This paper proposes a Privacy-Preserving Mandatory Logging Architecture based on User-Sovereign Cryptographic Governance. The framework introduces an immutable, tamper-resistant logging layer at the system level, combined with full cryptographic control delegated exclusively to the user. Instead of granting manufacturers, service providers, or governments access to behavioral data, all logs are encrypted end-to-end using user-derived keys generated from high-entropy personal secrets through modern key derivation functions.
