FACEBOOK-OWNED INSTANT MESSAGING SERVICE Whatsapp has half a billion monthly users, according to a note from the firm.
The company's user base has grown even after it entered into a $19bn relationship with Facebook that shocked Wall Street and rattled users.
A short note on the Whatsapp blog revealed the 500 million number, along with a couple of others.
"Thanks to all of you, half a billion people around the world are now regular, active Whatsapp users. In the last few months, we've grown fastest in countries like Brazil, India, Mexico, and Russia, and our users are also sharing more than 700 million photos and 100 million videos every single day," it said.
"We could go on, but for now, it's more important that we get back to work - because here at Whatsapp, we're just getting started."
The growth in users post-Facebook acqusition might be a bit surprising because of the backlash that the deal created. Whatsapp has tried to "set the record straight" and distanced itself from talk about privacy erosion and a boot to the face to security.
"Respect for your privacy is coded into our DNA, and we built Whatsapp around the goal of knowing as little about you as possible: You don't have to give us your name and we don't ask for your email address. We don't know your birthday. We don't know your home address. We don't know where you work. We don't know your likes, what you search for on the internet or collect your GPS location.
"None of that data has ever been collected and stored by Whatsapp, and we really have no plans to change that," wrote Whatsapp CEO Jan Kuom earlier.
"If partnering with Facebook meant that we had to change our values, we wouldn't have done it." µ
