#DeleteWhatsAppDay: More Relevant Than Ever

Five years ago today, on May 15, 2021, WhatsApp’s controversial new privacy policy came into effect. The update sparked global criticism and raised public awareness of the economic incentives behind data-driven online platforms. With users spending more time online, ever-growing volumes of data, and powerful new AI systems, the concerns raised back then are now even more justified than in 2021.

No to Online Surveillance, Yes to Digital Integrity

In response to increasing surveillance on the Internet and the weakening of our privacy that goes along with it, the “digital integrity” movement is forming resistance. In Switzerland, two cantons have already voted decisively to establish a fundamental right to “digital integrity” in their state constitutions. At the end of the month, the canton of Zurich will also vote on this issue.

“I have nothing to hide”: Why Privacy Matters

Does this statement make your hair stand on end? Unfortunately, the “nothing to hide” argument has persisted for far too long and often prevents any constructive discussion about privacy protection on the Internet. It’s high time to debunk it.

The Unwritten Rules of Chat Communication

Do you think instant messaging is the same as any other form of written communication? Think again.

Privacy for Everyone vs. Mass Surveillance for Crime Prevention

Have you ever heard the phrase “I have nothing to hide”? It’s often used by people who advocate government surveillance as a means of combating crime. According to this logic, however, anyone who is not a criminal has nothing to hide and therefore does not need an encrypted communication channel. This assumption is not only wrong, but also quite dangerous.

When Employees Leave: Secure Offboarding with Threema Work

Staff changes are part of every organization. In most cases, there are structured processes in place to ensure that nothing falls through the cracks. With employee departures, it is essential to take communication solutions into account – after all, trade secrets, customer data, and other company information must remain within the company and should not be accessible on the private devices of former employees.

What is data privacy? And why should your business care?

In today’s hyperconnected world, where every message, file, and decision passes through digital systems, data privacy has become more than a legal requirement – it’s a core business responsibility. However, many companies still view privacy as something to be “handled by IT” or as a matter of ticking boxes to comply with regulations. That mindset is outdated and dangerous.
