Google has closed its deal to buy fitness tracking firm Fitbit, the companies stated on Thursday. However, the US and Australian competition regulators were continuously probing of the $2.1 billion transaction.

Moreover, the Justice Department, that sued Alphabet Inc's Google in October for allegedly violating antitrust law in its search and search advertising businesses commenting on the Fitbit deal says, "has not reached a final decision about whether to pursue an enforcement action."

Commenting on the deal, Google states, "complied with the DOJ's (Justice Department's) extensive review for the past 14 months, and the agreed upon waiting period expired without their objection."

The company further adds, "We continue to be in touch with them and we’re committed to answering any additional questions."
The Australian Competition and Consumer Commission Chair Rod Sims said "depending on the results of our investigation, we will consider whether to take legal action on this matter."

It is rare for a big deal to close without antitrust approval.
Google won EU antitrust approval last month for its Fitbit bid after agreeing to restrictions on how it will use customers' health-related data.

Australia rejected similar restrictions proposed by Google, expressing concern that the company might block Fitbit rivals from connecting to phones running Google's Android operating software.

Fitbit makes a watch-like device to measure physical activity that competes with Apple Watch and others. Google said it was buying the company to compete in this market.

"We worked with global regulators on an approach which safeguards consumers' privacy expectations," Google said in a blog post, which said Fitbit had 29 million active users.

While Alphabet is best known for a free service, its search engine, it has many other businesses, including online advertising services, audio device and thermostat maker Nest, video streamer YouTube and self-driving car company Waymo.

Google's plan to buy Fitbit raised concerns when it was announced in late 2019 because of its already rich trove of data about people, what they buy, where they travel, and more.

Fit bit's fitness trackers and other devices monitor users' steps and calories burned. They also measure floors climbed, heart rate, and how long and how well people sleep. Alphabet shares closed down about 1percent on Thursday. The company is anticipated to retain Fit bit's 1,800 employees.
