The chief executive of WhatsApp has dismissed concerns that the acquisition of the popular messaging app by Facebook would result in less privacy for users.
In a posting on the company's blog, Jan Koum, 37, said on Monday a major motivation behind his creation of the app was his desire to ensure the privacy that he had never enjoyed while growing up under Soviet rule in his native Ukraine.
"Respect for your privacy is coded into our DNA, and we built WhatsApp around the goal of knowing as little about you as possible," wrote Koum, who noted that the site does not insist on knowing users' names or email addresses, and does not know their home addresses, employers, birthdates or internet search histories.
Koum insisted the $US19 billion ($A20.98 billion) sale last month of the company to Facebook would not change that, despite Facebook's renowned appetite for as much user data as possible.
"If partnering with Facebook meant that we had to change our values, we wouldn't have done it," Koum wrote.
