According to an investigation by the news website Bellingcat and the Dutch news agency De Correspondent, the fitness devices were leaking data belonging to the military or intelligence officials who could be exploited by a threat actors to spy on them.

“With only a few clicks, a high-ranking officer of an airbase known to host nuclear weapons can be found jogging across the compound in the morning,” explained the security researcher Foeke Postma that investigated the case with the Dutch news outlet De Correspondent.

“We can find Western military personnel in Afghanistan through the Polar site. Cross-checking one name and profile picture with social media confirmed one soldier or officer’s identity.”


The experts discovered detailed personal information, including home addresses, of military personnel, persons serving on submarines, Americans in the Green Zone in Baghdad and Russian soldiers in Crimea.

The exposure of such data poses serious risks to the military personnel as reported in a post published by Defensenews.com.

“Bellingcat was able to pinpoint the name of a “high-ranking officer” at a base known to host nuclear weapons. It took just a few clicks. Using the Polar Flow app and other information found on the internet, De Correspondent was able to collect a disturbing amount of one Dutch solider’s personal information.” reads the blog post published by Defensenews.com.

While the decision to opt-in and share training sessions and GPS location data is the choice and responsibility of the customer, we are aware that potentially sensitive locations were appearing in public data, and have made the decision to suspend the Explore until further notice.” reads the statement published by Polar.

“I have seen statements that suggest that Polar leaked data – Did Polar leak any data?Contrary to what has been reported—it’s important to clarify that Polar has not leaked any data. Furthermore, there has been no breach of private data.”

De Correspondent investigation revealed that only about two percent of Polar users chose to share their data, but journalists and experts were able to collect sensitive data from military or civilian personnel.

“We found the names and addresses of personnel at military bases including Guantanamo Bay in Cuba, Arbil in Iraq, Gao in Mali, and bases in Afghanistan, Saudi Arabia, Qatar, Chad, and South Korea,” states the De Correspondent report.
