The growing list of European organisations that ban personal messaging apps at work
From German factories in 2018 to entire governments in 2026 — the organisations that decided work conversations don't belong on personal apps.
July 8th, 2026
If using personal messaging apps for work has ever felt a bit wrong to you, you're not alone. In surveys, around seven out of ten office workers¹ say they share work information over these apps. And many of us have had the same quiet question while typing: should this conversation really happen here?
That feeling makes sense. The real risks come down to two things: control over the channel, and a record of your conversations (a "paper trail") when your organisation needs one. On a personal app, your organisation cannot decide what is kept and what is deleted. It cannot control who is part of a conversation. And it cannot show last year's messages when a regulator, a court, or a customer dispute requires them.
A growing number of European organisations have understood this and acted on it. What started as a data-protection question in German industry has become, year by year, a question of record-keeping, compliance, and digital sovereignty across Europe. We have collected the cases below and the list covers both formal bans and formal restrictions.
We plan to keep this list up to date. If you know an organisation that belongs on it, send us a message (hello@birdy.chat) and we will add it to the list.
Notes:
¹ our survey found that 75% of professionals use personal chat apps at work while a survey of 12k people in 2021 found that 71% professionals share business-critical data on instant messaging apps.
² European Commission (2020): formally recommended a switch to Signal, not a ban of messaging apps.
Productively yours,
