The article introduces gentle quantum leakage as a measure of information leakage to avoid detection. It discusses the use of gentle measurements to encode an eavesdropper's intention to evade detection. The study shows that global depolarizing noise can reduce gentle quantum leakage, enhancing privacy and security. Lower bounds for gentle quantum leakage are presented based on asymmetric approximate cloning. The article also explores the interplay between measurement informativeness and state collapse in quantum systems. It highlights the importance of investigating eavesdroppers' worst-case information extraction while considering their chances of being detected.
