Everyday Challenges at School

Communication in schools is demanding: teachers, parents, and students need reliable information, clear agreements, and fast, uncomplicated exchanges. Conventional tools quickly reach their limits due to data protection issues, disorganized group chats, or a lack of permission controls.

Threema Education is a privacy-compliant, structured, and easy-to-use solution designed for schools. No phone numbers are required, no data is shared with third parties, and the school has full control. This ensures that communication remains secure, targeted, and efficient.

Privacy-Compliant Communication at Schools

From parent-teacher meetings and absence notifications to canceled classes and group projects, schools face countless situations every day that require reliable communication. Yet teachers often resort to private messengers, which can leave them in a legal gray area. Students may disclose personal data without adequate protection, parents struggle to keep track of everything, and the school has no control over the exchange of information.

To be legally sound and compliant with privacy regulations, school communication requires clear structures, secure channels, and full control by the school.

Trust Starts with Security

Confidential information is shared daily in schools. It’s not enough for messages to arrive quickly – they must also be transmitted securely and with minimal data collection. Who has access? What information is being recorded in the background? Many messaging apps collect more information than is apparent at first glance.

Threema Education focuses on robust data security: no phone numbers, no centrally stored metadata, no user profiles. Instead, it offers true end-to-end encryption and gives the school full control, ensuring that sensitive content remains confidential.

Simple, Secure, Structured: Communication for Everyday School Life

Confidential communication, controlled groups, and no data risk: this is what reliable digital school communication consists of.

Direct communication without phone numbers

Teachers, parents, and students can communicate securely without sharing private mobile phone numbers.

Targeted information distribution to groups

Send messages to entire classes, parents’ associations, or departments with just a few clicks – ideal for schedule changes, sick notes, or organizational information.

Structured group communication

Easily create groups for classes, projects, or clubs, while teachers keep the overview.

Central administration and clear responsibilities

The school determines who can create groups, send messages, and share files.

Robust data protection and full data sovereignty

No phone numbers are required, no personal metadata is stored, and no data is shared with third parties.
