The article attempts to analyze the process control of correspondence stored in virtual memory, i.e. in the so-called Cloud Computing. The study is an attempt to answer the question of how mobile devices and clouds are examined and what impact the law on privacy has on the implementation of procedural activities. The growing interest in cloud computing results in the emergence of many new legal problems, which translate into, among others, on the practice and operation of law enforcement agencies. First, the concept of „cloud computing” was discussed and the provisions on obtaining electronic evidence were analyzed. The independence of ICT systems from the functioning of a classic work environment based on a single workstation also allowed us to raise the question of the cross-border nature of services provided in the cloud. IT data transmitted via cloud computing can be saved on several devices located in different countries.
