Yesterday, we heard speculation — via a Techcrunch report — that Facebook (NASDAQ:FB) was discussing a buyout of WhatsApp, a mobile messaging service.

Now, according to AllThingsD, WhatsApp says it isn’t interested in selling — even though Facebook and Google (NASDAQ:GOOG) have shown strong interest in the company in the past.

WhatsApps’ CEO and co-founder, Jan Koum, has alluded to wanting to keep WhatsApp an independent company, and the firm responded to AllThingsD with a statement refuting the buyout report:

“The TechCrunch article is a rumor and not factually accurate. We have no further information to share at the moment.”

When it comes to mobile, WhatsApp seems to have cracked the code. It delivers more than 10 billion messages per day and charges a low-cost payment plan to its users. It is the No. 1 paid app on Apple’s (NASDAQ:AAPL) App Store and has been downloaded more than 100 million times on Google Play.

Considering WhatsApp has done all that with just a handful of employees, Koum and his company probably don’t need Facebook or Google’s help.
