Secure help desk over Threema

Support, sealed.

TacitDesk is a help desk your customers reach from the Threema app. Messages travel end-to-end encrypted, your agents answer from a desk carrying your brand, and nothing passes through email, SMS or a chat widget on the open web.

For conversations that should stay between you and your customer

Law firms, clinics, accountants, security teams and anyone whose support traffic is sensitive by default.

No phone number, no app of your own to build

Customers message a Threema ID that carries your name and avatar. Threema needs no phone number or email address to use.

Answer with people, rules, or an assistant

Auto-replies outside hours, routing to your agents inside them, and an optional AI assistant that works from a brief you write.

Two ways to run it

Same software, same dashboard. The difference is where the messages are decrypted and who holds the key.

Turnkey

We host it

Your branded help desk is live in days. TacitDesk runs the service on servers in the EU and Switzerland and holds the Threema key for your desk.

Key custody
TacitDesk, one key per customer, in a managed key store
Where decrypted
Our EU/Swiss servers, under a data processing agreement
Who can read
Your agents in the dashboard. TacitDesk can technically read messages and says so plainly.
Good for
Teams without infrastructure, fast starts, trials

Self-hosted

We install it on your hardware

TacitDesk installs, configures and maintains the same software on your own servers or private cloud. The key never leaves your building.

Key custody
You. TacitDesk never sees it.
Where decrypted
Your hardware only
Who can read
Your agents. Not TacitDesk, and not anyone who compels TacitDesk.
Good for
Regulated sectors, data-residency rules, public bodies

Start hosted and move to your own hardware later. The export path, including your key material, is part of the service.

We set you up with a private demo: you write the instructions, pair your Threema app with a short code, and talk to it.
