Get creative with Threema for Android’s new image editor

Threema 3.1 for Android introduces new image editing options. You can now spice up your images by drawing on them, adding text, and inserting stickers – without leaving the Threema app.

First, select the image you would like to send. In the preview, tap the paintbrush icon in the title bar to open the image editor. Draw whatever you like, add text, and insert, move, resize and rotate stickers. Tap and hold any item to flip it horizontally, bring it to the front, or delete it. Of course, you can also adjust the color of the brushstrokes and the text.

As always, the update includes some bug fixes and general improvements. Visit the change log.

Threema 2.8.1 for iOS: Message drafts and more

A new Threema version for iOS has just hit the App Store. The 2.8.1 update for iOS introduces message drafts: If you compose a message without sending it, the message will be saved as draft, and it is indicated in the chat list that there’s an unsent message in that conversation. Furthermore, it’s now apparent at a glance which messages are new in a chat thanks to a divider bar.

This update also includes some other additions and improvements. To learn more, please consult the change log.

Threema Web. Threema’s web client is here

Threema arrives on the desktop. Threema Web allows to conveniently chat from the computer without compromising security. The handling is intuitive, and the user has full access to all chats, contacts, and media files.

Highest security and data restraint

As to be expected, Threema’s way of implementing a web client ensures both highest security and maximum data restraint. Instead of using a server for message synchronization, Threema Web establishes an encrypted direct connection between browser and mobile device. This way, messages can be synchronized without having to pass a server. If browser and mobile device are connected to the same network, the data packets never leave the network. In contrast to common, server-based approaches, Threema Web significantly reduces the digital footprint and limits the generation of metadata to the bare minimum. After a session has ended, the synchronized messages are deleted immediately on the desktop. Threema Web acts as an extension of the Threema app and meets the high security standard set by the Threema app.

Complete message synchronization

The sole requirement to use Threema Web is a current web browser (Chromium, Google Chrome, Mozilla Firefox, or Opera). By scanning a QR code, browser and mobile device are connected at once. All chats are fully available on the desktop, and the devices are synchronized seamlessly. UI-wise, Threema Web is modeled after the Threema app. Messages are sent and received just like on the mobile device; images and files can be conveniently sent using drag and drop.

Open source

Threema Web is open source; the source code is available on GitHub, and even self-hosting is possible. To handle the direct communication between browser and mobile device, SaltyRTC is used. SaltyRTC adds an additional encryption layer to the open standard WebRTC and ensures a secure connection between browser and mobile device. Signaling is also carried out by SaltyRTC using strong encryption. The SaltyRTC protocol was developed specifically for Threema Web and is based on the tried and trusted NaCl cryptography library, which is highly regarded by experts.

Data Privacy Day – Threema 50% off

January 28 is Data Privacy Day. This holiday was established in order to raise awareness for data protection and to point out the dangers of a decline in privacy. Privacy awareness is more important than ever. In addition to surveillance programs by governments and data breaches, privacy violations by companies undermine the privacy of Internet users.

Users are often unaware of the amount and the kind of data they disclose by using certain online services. There’s also a lack of awareness for the consequences of giving up one’s privacy. Data is power. Once collected, data can be endlessly reproduced and stored until the end of time. What’s more, user data might lead to unforeseen conclusions about the users, especially when collected in large quantities and merged with data from other sources.

Threema was designed to generate as little data as possible in the first place. For where there is no data, no data can be misused.

The Data Privacy Day is a great opportunity to reconsider one’s communication habits. Threema is a valuable tool to ensure security and confidentiality of your communication. On the occasion of this year’s Data Privacy Day, the Threema app is available for half the price on all supported platforms.

The 50% sale ends on Sunday, January 29, at 10 p.m. CET.

Message quoting in Threema for iOS

Threema for Android recently introduced a useful quote feature. With Threema 2.8.0 for iOS, this feature is now also available on iOS. Message quoting will come in handy in lively group discussions or whenever you need to unambiguously reference previous text messages.

To quote a text message on iOS, tap and hold it until the context menu appears. There, tap the quotation mark icon, and the quoted message will appear above the text input field. You can then compose and send your message like you usually would. In the chat, the quoted message is indented and prepended to your new message so that it’s evident what you are referring to.

The 2.8.0 update also adds support for Romansh, Switzerland’s fourth national language, and it includes miscellaneous improvements and bug fixes.

By the way, the first Threema version was published exactly four years ago today. Thank you for all the support over the years!

Reseller program for Threema Work

Mobile messaging is becoming increasingly important in today’s business communication. Frequently, however, chat apps are used which employees already use for personal communication. Many of these apps don’t meet legal privacy requirements and aren’t suitable for business purposes due to insufficient security.

Companies which are aware of the delicacy of this situation have switched to Threema Work, the secure and privacy-compliant messaging solution for businesses. All kinds of companies use Threema Work – well-known corporations, numerous small and medium-sized enterprises, and NGOs.

To promote the rapid spread of Threema Work, we are introducing a reseller program. Qualified IT service providers can now offer Threema Work directly to their customers and benefit from favorable resale and referral conditions.

New quote feature in Threema for Android

Threema 2.92 for Android provides a handy quote feature which allows to unambiguously reference previous text messages. This can be particularly useful in lively group discussions.

To quote a text message, tap and hold it until the context menu appears in the title bar. There, tap the quotation mark icon, and the quoted message will appear above the text input field. You can then compose and send your message like you usually would. In the chat, the quoted message is indented and prepended to your new message (as well as marked with the color corresponding to its author) so that it’s evident what you are referring to.

We have also streamlined the menus and revised the navigation. New chats, group conversations, and distribution lists can now be created via the Floating Action Button (and no longer via the toolbar). And for better usability, we have reorganized and consolidated the items in the side drawer.

On top of that, this update includes numerous other improvements and optimizations along with some bug fixes. For more details, please consult the change log.
