You’re sitting in a coffee shop, talking to a friend. Suddenly, the waiter shows up, asks for your phone numbers, and wants to know who else you’re friends with and what you’re talking about. Do you provide the requested information? Would you provide the information if, in turn, you wouldn’t have to pay the bill? Is it safe to assume that you have something to hide if you don’t enter into this deal?
Internet users who disclose their privacy in order to access free online services often do so on the grounds of having “nothing to hide”. However, as closer inspection reveals, this position is untenable. Having nothing to hide might be a desirable state of affairs, but it doesn’t entail that it’s safe to disclose one’s privacy.
If you don’t feel comfortable providing the requested information to the waiter, that doesn’t mean you have something to hide. It simply means you wish to preserve the privacy you rightfully deserve. Maybe you’re discussing something mundane, like the weather, but you think it’s none of the waiter’s business. Also, you don’t know what the waiter might do with the obtained information and why he’s keen on acquiring it in the first place.
If you do not carelessly disclose personal information to strangers in real life, you probably shouldn’t provide the same information to online services, either. By combining several data points, it’s easy to draw a detailed picture of you; one which reveals far more than each data point would on its own – and one that could reveal more about you than you would imagine.

Threema 4.0 for iOS is here! This major update adds support for Threema Web and allows to adjust notification settings on a per-chat basis. On top of that, it includes other enhancements as well as several under-the-hood improvements.
Web client for iOS
With Threema Web, you can conveniently use Threema on the desktop without compromising security. Simply connect Threema with your browser by scanning a QR code. You can then send and receive Threema messages on your computer, where all your chats are fully available. Save or send images and other files with ease by dragging and dropping.
As with the web client for Android, Threema Web for iOS was developed with security and privacy in mind. The communication between phone and PC is fully end-to-end encrypted, and after the session is terminated, the synchronized messages are immediately deleted in the browser. Technical details are documented in the Cryptography Whitepaper.
Individual notification settings
Notification settings can now be adjusted on a per-chat basis, allowing you to disable or mute notifications of any single or group chat indefinitely or for a specified amount of time. If, for example, the current topic of a group conversation does not concern you, simply deactivate notifications of the group for a given amount of time.
The 4.0 update includes many other changes and additions. For example, you can now delete multiple media files at once and create groups of up to 100 members. For all the details, please refer to the change log.

We have recently introduced Threema Education, a secure and privacy-compliant chat solution for schools and educational institutions.
Today, Threema Education becomes even more compelling because there are no more recurring costs. With a one-time purchase, schools can now permanently enable students, parents, and teachers to chat without exposing their privacy. Considering a usage term of five years, Threema Education is only CHF 1.82 (€ 1.58) per year for one user.
The General Data Protection Regulation (GDPR) has sparked a lively debate over whether the use of chat services for school purposes is legal or not. Due to the rigorous privacy protection, the use of Threema in schools is safe and GDPR-compliant.
Since Threema doesn’t require a SIM card or a phone number, it is also ideally suited for school tablets.

Often, when I ask people to join me on Threema, they balk. “Why should I pay for Threema, when I can use other encrypted messaging apps for free?” they ask.
Actually, there are a lot of reasons why Threema is worth paying for.
For starters, Threema is simply more enjoyable to use than other messengers and offers everything one would expect from a modern chat app, even allowing for encrypted phone calls.
Also, as a Swiss company, Threema is protected by Switzerland’s stringent and user-friendly privacy laws, meaning that it’s not subject to the vulnerabilities of America’s weak privacy protections like U.S.-based messaging apps are.
In addition, unlike many other apps, Threema doesn’t require your phone number, which means that its users can communicate with each other completely anonymously.
While each of these is a good reason to use Threema, there is another crucial aspect that is often ignored. It may seem counterintuitive, but the fact that Threema is a paid app is one of its greatest strengths.
At Threema, it’s the users, not investors, who are in charge
Threema does not operate under a typical Silicon Valley type of financial model, which is based on catering to advertisers. Instead, Threema charges a fee because, naturally, it has to cover its development and payroll costs. But what this means is that Threema is actually owned by its users and not by investors or venture capitalists who have an agenda.
Yes, mining a user’s data or accepting outside funding can allow an app to be “free,” but the truth is that nothing is free. If you’re not paying for a service, you can expect that your data is being exploited in some way, as we saw with Facebook’s Cambridge Analytica scandal. Threema’s reliance upon its users for support means that its only incentive is to make the best encrypted messaging app possible.
When you use online products that don’t charge for their services, you’re giving your privacy away for free. When you pay for a service like Threema, you’re paying to protect it.
Attention, educational institutions! There is now a special offer for you: Threema Education. You benefit from a 60% discount compared to Threema Work Enterprise.
Instant messaging is arguably the most popular means of communication, especially among the youth. Students interact lively via chat apps and use them to coordinate their school projects. Teachers have also started using instant messaging to quickly and conveniently assign homework, organize field trips, etc. However, conventional chat apps are not suitable for schools due to their poor privacy protection; experts strongly advise against their use.
Stay on top of instant messaging. Get Threema Education to protect the privacy of both students and teachers, and allow them to strictly separate personal and school communication.

If you read the Threema blog, you’re probably someone who understands the value of end-to-end encryption to protect your communication and your messages. But did you know that metadata can reveal more about you than the actual message content?
Every message that you send leaves a trail of so-called metadata. This can include a record of extensive information of who you talk to, your online status, and the composition of your groups. It can even be used to determine where you are when your messages are sent.
Not only companies and social networks know that this information is of utmost value. Also governments and hackers know that metadata can be used to learn intimate things about you, which is why metadata surveillance has become routine. In fact, in 2013 the Guardian reported on the United States’ National Security Agency’s massive metadata collection program.
Good news for iOS users. Threema Web for iOS is coming along great. We are close to the finish line, but there is still quite some work ahead. We’re anticipating a public beta by May. Stay tuned for more information. Thank you for your patience!
The aim of the new General Data Protection Regulation (GDPR) is to improve the data privacy of EU citizens and to make services with insufficient privacy protection accountable. The new law will enter into force in May 2018.
Security and privacy protection have always been Threema’s guiding principles. No technical adjustments were necessary to meet the GDPR requirements. Hence, nothing changes for Threema users.
When lively discussions occur in group chats, it’s easy to lose track. It often happens that some members engage in a conversation that is of little interest to the others. This is where (temporarily) muting the group comes in handy. However, this involves the risk of reading an important message too late or missing it altogether due to the flood of incoming messages.
Thanks to the new “mention” feature, this is now a problem of the past: Address group members by mentioning them, and they will receive a notification even if the group is muted (if configured accordingly). Simply type an “@” character in the text field, and select the desired contact to mention them.
As to be expected, the “mention” feature was implemented with privacy and security in mind. When mentioning someone, not their name but their Threema ID is sent, which prevents privacy leaks. If the mentioned Threema ID matches a contact in a recipient’s address book, the appropriate name is displayed instead of the Threema ID.
Mentions are fully supported in Threema for Android. On iOS, mentions are displayed correctly but cannot be created at this time. For Windows Phone, the next app update will add support for displaying mentions.
Threema 3.4 for Android contains numerous other changes and additions, including improvements for Threema Web. For all the details, please consult the change log.
Threema calls enjoy great popularity. Thanks to end-to-end encrypted voice calls, privacy advocates can talk on the phone with a clear conscience – tap-proof and in brilliant voice quality.
Today, Threema for iOS gets a small but useful feature: While a Threema call is ongoing, you can continue to use the app like you normally would. On the call screen, simply tap the arrow in the top left corner, and you’re back in the app. Accessing the app while on the phone might come in handy if, for example, you want to send your conversation partner your current location or a document to be discussed.
To learn more about the other improvements the 3.0.6 update contains, please refer to the change log.
