The Owner takes appropriate security measures to prevent unauthorized access, disclosure, modification, or unauthorized destruction of the data. The data processing is carried out using computers and/or IT-enabled tools, following organizational procedures and modes strictly related to the purposes indicated. In addition to the Owner, in some cases the data may be accessible to certain types of persons in charge, involved with the operation of Loop · Brain Puzzle (administration, sales, marketing, legal, system administration) or external parties (such as third-party technical service providers, mail carriers, hosting providers, IT companies, communications agencies) appointed, if necessary, as Data Processors by the Owner. The updated list of these parties may be requested from the Owner at any time.

Place

The data is processed at the Owner's operating offices and in any other places where the parties involved in the processing are located.
