Question 1

What is Secret Ink?

Accepted Answer

Secret Ink is a self-hosted, end-to-end encrypted communications platform — messaging, groups, channels, voice and video calls, and meetings — that organisations run on their own servers and brand as their own. It is a private alternative to WhatsApp, Slack and Zoom.

Question 2

Is Secret Ink self-hosted / on-premise?

Accepted Answer

Yes. Secret Ink deploys with Docker on your own infrastructure — on-premise or private cloud — so your data never leaves your walls. It is also available as a fully managed, hosted plan.

Question 3

Is Secret Ink end-to-end encrypted?

Accepted Answer

Yes. Messages, files and calls are encrypted on the device. The server is a blind relay that only ever handles encrypted data — never plaintext messages, files, calls or keys.

Question 4

What platforms does Secret Ink support?

Accepted Answer

iOS, Android, Web and Windows Desktop. Secret Ink is live on the Apple App Store and Google Play.

Question 5

How much does Secret Ink cost?

Personal is free. Managed (hosted by Secret Ink) is from US$10 per user per month with servers included. Sovereign (self-hosted on your own dedicated servers) is US$30,000 per year with full data sovereignty.

Question 6

Who is Secret Ink for?

Accepted Answer

Governments and public sector, banking and finance, legal, healthcare, defence, and any enterprise with data-residency or data-sovereignty requirements.
