Before video call features came standard on mobile phones (shoot, almost before mobile phones), there was Skype. Launched in 2003, the former king of video calls has added features in an effort to keep up with the booming video call competition — recently they even partnered with the new Space Jam movie so you could have Lebron James in your background. Skype lets users blur their background for extra privacy, use real-time language translation and unlike some of the other apps on our list, call regular phone numbers. The video call app is owned by Microsoft these days, which means Skype integrates with services like Microsoft Teams.

What could happen if something goes wrong?

Skype has had some privacy concerns in the past, most notably when it came to light that Microsoft, which owns Skype, allowed contract workers in China to listen in to Skype calls with "no security measures" in place. It has since changed this practice, but it is a good reminder that even companies with decent security practices can handle your private data and conversations sloppily. Because Skype has been popular for a number of years, it has become a target for malware and phishing attacks. Users are able to set up two-factor authentication on Skype, which we recommend to help keep that conversation you're having with Grandma from being invaded by some angry troll. Skype doesn't use the stronger end-to-end encryption on phone or video calls, which, boo! Users can protect their text chats by enabling “private conversations.” Microsoft does collect a fair amount of data and says they may share this with third-parties like Facebook and Verizon for advertising purposes. It also says it combines data with third-parties such as data brokers, which can include your location. This isn't great. It’s also, unfortunately, not uncommon.

What data does the company collect?

How does the company use this data?

Microsoft uses data to advertise and market to you, which includes sending promotional communications, targeting advertising, and presenting you with offers. It does use your data to target you with advertising within Microsoft web properties. It also allows numerous partners like Verizon and Facebook, to collect data about your online activity for advertising purposes, and to place their own ads. Microsoft also extensively combines its data with third parties, such as data brokers for demographic data, service providers that help determine your device’s location, marketing partners, third parties that deliver experiences through Microsoft products, and publicly-available sources, such as open government databases.

How can you control your data?

Most data can be accessed or controlled via the Microsoft Privacy Dashboard. Data retention details are stated in the part of the privacy policy that is hard to access, and does not include clear retention time frames. Skype allows hosts to add and remove people from calls, mute users, toggle video and subtitles on and off, share screen, send an emoji reaction, and record calls. Those who pay for Skype for Business can choose who can enter, disable instant messages, mute all participants and block participants video.

What is the company’s known track record of protecting users’ data?

Needs Improvement

In January 2020, it was reported that Skype was using contractors in China to listen to Skype calls with allegedly no security measures in place. The company also shared login credentials of users with contractors. The company spokesman claimed that the company ended its grading programs for Skype. Also in January 2020, a report revealed that 250 million Microsoft customer records, spanning 14 years, had been exposed online without password protection.

User-friendly privacy information?


It was difficult to find answers to some essential questions. For example, which type of data is collected, or what are data retention periods. In addition, the policy is for all-things-Microsoft, so it is difficult if impossible to find Skype-specific info.
