The Threema advantage, or why encrypting messages isn’t enough

Since WhatsApp started offering end-to-end encryption of message contents, we are often asked whether there are still advantages of using Threema. There’s a lot to highlight, which is why we have compiled a list of privacy-related features that set Threema and WhatsApp apart.

The sole encryption of message contents is insufficient as long as lots of metadata can still be collected because, as Stewart Baker (former NSA General Counsel) puts it:

“Metadata absolutely tells you everything about somebody’s life. If you have enough metadata, you don’t really need content.”

For this reason, Threema was designed from the ground up to generate as little metadata as technically possible. This is one of the key differences between Threema and other messengers.

Update 2.7.0 for iOS: Share from within other apps

The new Threema version for iOS offers a share extension. This allows you to share images, videos and any other file from within other apps via Threema.

Additionally, the update fixes some bugs and brings general VoiceOver improvements.

Threema for Android - Release 2.7 with animated GIF support and more

Now also available on Android!

Threema for Android now displays animated GIFs directly in chat bubbles, both in group chats as well as in regular chats.

Furthermore, voice message playback was improved. We also added a new feature that allows you to simply clone existing groups and made it easier to manually add new contacts.

For further details about the changes in this release please consult the change log.

iOS Release 2.6.2 with animated GIF support and more

Spice up your chats!

Threema for iOS version 2.6.2 now displays animated GIFs directly in Threema’s chat bubbles, both in group chats as well as in regular chats.

We also improved the built-in video processing and were able to raise the maximum length of video messages to 15 minutes for moderate quality and 3 minutes for high quality videos.

In addition, the media browser was upgraded to give easy access to any media type including files.

For further details, please consult the change log.

Threema for Windows Phone: New features and UI tweaks

With the latest update, Threema’s Windows Phone version gets some new features, the most important being the agree/disagree functionality: It allows to agree or disagree with an incoming message without triggering a push notification on the chat partner’s device. Instead, a “thumbs up” or “thumbs down” icon appears next to the corresponding message. This feature is now available on all platforms.

Media files (i.e., videos, pictures and voice messages) can use up a considerable amount of disk space. For this reason, the media management has been enhanced, allowing you to delete media files globally or on a per-chat basis, which makes freeing up disk space a snap.

If some of your group chats are reaching the limit of members, we have good news for you: The maximum group size was raised to 50.

Those are three of the functional improvements of the update 1.5.0, but there are visual enhancements, too. The chat wallpaper is now customizable, the default being our illustrative all-over pattern, and you can adjust the color of speech bubbles to your liking.

For further details, please consult the change log.

Dark theme and agree/disagree feature now available on iOS

With its latest Android update, Threema introduced a new agree/disagree feature. This handy feature is now also available on iOS. It enables you to agree or disagree with an incoming message without triggering a push notification on the chat partner’s device. Instead, a “thumbs up” or “thumbs down” icon appears next to the corresponding message. This unique feature is not offered by any other messenger, which shows that – besides security – innovation is a driving force behind Threema’s development. The feature will be available on Windows Phone soon.

With its 2.6.0 update, the iOS version catches up with the Android version. Like on Android (and Windows Phone), there is now a dark theme available which looks sleek and elegant. Add to that the new chat wallpaper, which is another visual enhancement.

Furthermore, the maximum group size was raised to 50, VoiceOver support was improved to make Threema easier to use for the visually impaired, and thanks to the streamlined setup process, initially setting up Threema is now more intuitive and pleasant.

Data Privacy Day – On the collection of user data and how to protect one's online privacy

Due to frequent news about surveillance by governments, data breaches by companies and attacks by hackers, concerns about data privacy have been growing over the past years. The Data Privacy Day, which takes place on January 28 every year, aims to raise public awareness on the subject.

Data is power. Personal data that has been collected can be preserved indefinitely, it can be endlessly reproduced, and it might eventually fall into the wrong hands. Therefore, the best protection against data abuse is to prevent the generation of data in the first place. There are many services that protect user data, but Internet users need to care about their data in order to take the right measures.

Together with Tresorit and ProtonMail, Threema would like to help to raise awareness about data privacy. In view of the occasion, Tresorit has created a website that shows what user data is being collected by large online companies. The point is to remind us that our data has a high value for the companies we give it to, which might lead us to rethink our behavior. On Tresorit's Blog, the CEOs of the three companies also share some tips on how to protect one's online privacy.

Speaking of privacy: Have you ever read Threema's privacy policy? It's not only transparent and comprehensible, it literally fits on a sheet of paper.

Version 2.6 for Android: Unique agree/disagree feature and more

New agree/disagree feature, individual notification settings per chat, up to 50 members in group chats – those are just some of the additions Threema’s 2.6 update for Android provides.

New agree/disagree feature

Threema’s acknowledge feature enjoys great popularity. It allows to confirm an incoming message without triggering a push notification on the chat partner’s device, providing an unobtrusive way of stating that you have taken note of – and agree with – a message. There are times, however, when you have to (silently) disagree. With Threema 2.6 for Android, you can do that:

  • In a single chat, tap and hold on a received message.
  • In the header, “thumbs up” and “thumbs down” icons appear.
  • To agree or disagree with the selected message, tap “thumbs up” or “thumbs down”, respectively.

This feature is currently only available in single chats on Android, but Threema versions for other platforms will follow.

Individual notification settings per chat

This might sound familiar: When disruption is most inconvenient, a lively discussion (on a topic you couldn't care less about) arises in some group chat, forcing you to take extreme measures like turning off your phone. With Threema 2.6 for Android, notification settings can be adjusted on a per-chat basis, allowing you to mute that one group chat specifically. You can choose to mute it indefinitely or only for a set amount of time.

Notification sounds can also be adjusted for each chat individually, enabling you to tell who has sent an incoming message before you pick up the phone.

Maximum group size raised to 50 and other improvements

Additions and changes in Threema 2.6 for Android include:

  • 170 new emojis added
  • Completely redesigned setup process
  • Raised max. group size to 50
  • New PIN lock screen with support for fingerprint reader and other system lock screen facilities (Android 6.0+)
  • Status messages for incoming or changed poll votes
  • Performance improvements
  • Two obsolete permissions removed
  • New agree/disagree feature
  • Individual notification settings for each chat

Improvements in group management and design (iOS)

This update also contains design enhancements. For example, the chat list and contact's detail view have been revised. Threema provides a new option to disable push notifications per contact. Many other improvements are waiting to be discovered.
