Classroom communication in group chats
The GDPR-compliant messenger for schools. For protected communication between teachers, parents, and students.
Communication in schools is demanding: teachers, parents, and students need reliable information, clear agreements, and a fast, uncomplicated way to get in touch with each other. Conventional solutions 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 communication solution that was developed specifically for schools. No phone numbers are required, no data is shared with third parties, and the school has full control. This ensures that the flow of informationremains secure, targeted, and efficient.
From parent-teacher meetings and absence notifications to canceled classes and group projects, schools face countless situations every day that require reliable information exchange. 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.
Confidential topics are discussed every day in schools. It’s not enough for messages to be delivered quickly – they must also be processed securely and with minimal data collection. Who has access? What information is being recorded in the background? Many messaging apps collect more information than you might think.
Threema Education is committed to data protection: 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.
Confidential exchange, clearly defined groups, and no data risks: this is how digital collaboration becomes a reliable pillar of school operations.
Teachers, parents, and students can communicate securely without sharing private mobile phone numbers.
Send messages to entire classes, parents’ associations, or departments with just a few clicks – ideal for schedule changes, sick notes, or organizational information.
Easily set up groups for classes, projects, or clubs, while teachers keep the overview.
The school determines who can create groups, send messages, and share files.
No phone numbers are required, no personal metadata is stored, and no data is shared with third parties
Polls for scheduling appointments, secure sharing of photos, documents, and forms, plus clear guidelines for availability outside of class hours
