We have been fighting for transparency and stronger regulation of the use of IMSI catchers by law enforcement in the UK since 2016. The UK police forces have been very secretive about the use of IMSI catchers – maintaining a strict “neither confirm nor deny” (NCND) policy. In our efforts to seek greater clarity we wrote to the UK body which monitors the use of covert investigatory powers, the Investigatory Powers Commissioner’s Office (IPCO), asking the Commissioner to revisit this…

What if we told you that every photo of you, your family, and your friends posted on your social media or even your blog could be copied and saved indefinitely in a database with billions of images of other people, by a company you've never heard of? And what if we told you that this mass surveillance database was pitched to law enforcement and private companies across the world?

The Court referred to cases dating back to the 18th century, which demonstrate the common law’s insistence that the Government cannot search private premises without lawful authority even in the national security…

In 2019, we exposed the practices of five menstruation apps that were sharing your most intimate data with Facebook and other third parties. We were pleased to see that upon the publication of our research some of them decided to change their practices. But we always knew the road to effective openness, transparency, informed consent and data minimisation would be a long one when it comes to apps, which for the most part make profit from our menstrual cycle and even sometimes one’s desire to…

Numerous sexist, mysoginistic, homophobic and racist practices are flourishing online, in ways that are harder for national authorities to stop than when abuse takes place offline. One of these practices is ‘revenge pornography’, which involves online distribution of private sexual images without the consent of the person depicted.
One victim of image based sexual abuse (more commonly known as revenge porn): Chrissy Chambers. Chrissy was 18 years old when her boyfriend convinced her to spend…

MI6 has been forced to apologise to the Investigatory Powers Tribunal after two of its officers asked court staff to return documents relating to MI6’s use of agents and not show them to judges. The Tribunal suggested MI6’s actions were “inappropriate interference”.
The revelation emerged in an ongoing legal case considering what crimes intelligence informants are allowed to commit, after it was revealed that MI5 maintains a secret policy under which agents can be “authorised” to…

In September 2019, PI published the report Your Mental Health for Sale. Our investigation looked into popular mental health websites and their data sharing practices.

Some websites were also found sharing…

Name: Google/Fitbit merger
Age: Gestating
Appearance: A bit dodgy. One of the world’s biggest tech giants, trying to purchase a company that makes fitness tracking devices, and therefore has huge amounts of our health data.
I don’t get it. Basically Google is trying to buy Fitbit. As if Google doesn’t already have enough data about us, it now wants huge amounts of health data too.
Oh, Fitbit, that’s that weird little watch-type-thing that people get for Christmas, wear for about a month…

It’s 7:33 am. Lila’s GoogBit watch vibrates. “You got 6 hours and 57 minutes of sleep last night, including 2 hours and 12 minutes of deep sleep”, the watch reads. “In total, you tossed and turned for 15 minutes only”. Taking into account Lila’s online browsing activity, her sleep pattern, the recent disruptions in some of her other biorhythms, as well as her daily schedule, GoogBit watch has calculated the very best minute to wake her up.

This week saw the release of a coronavirus tracking app within the United Kingdom, initially to be trialled in the Isle of Wight. Privacy International has been following this closely, along with other ‘track and trace’ apps like those seen in over 30 other countries.
The UK’s app is no different. It is a small part of a public health response to this pandemic. As with all the other apps, it is vital that it be integrated with a comprehensive healthcare response, prioritise people, and…

One year on we find ourselves in a situation where 1 May protests in the streets will not be going ahead. Rights have been restricted around the world. Sadly we’re seeing some actors exploit this public health crisis to enhance their own power, expanding surveillance and opportunism.
Against this challenging back-drop we wanted to…

The recent rise of spyware as an “off-the-shelf” product that anyone can purchase has been extremely worrying, as installing spyware on someone else’s phone means getting access to their contacts, their messages, their google searches, their location and more - all without them knowing.
Spyware is, increasingly, becoming another way for abusive spouses to control and monitor their partners. Nearly a third of…
