Pursuant to § 28 of the Federal Data Protection Act (BDSG), I draw your attention to the fact that the data required in the course of the business transaction are processed and stored by means of a computer system in accordance with § 33 (BDSG) (eg provider side Outlook / Exchange Server, private PDA / folder) .
Of course, personal data will be treated confidentially and under no circumstances will be passed on voluntarily. Theft, hackers or similar I try by careful handling (firewall, self-updating virus protection program) to avoid course.
