5 Reasons to Use Matrix-Synapse with Element for Family Privacy and how to set it up

In an age when our digital communications are constantly monitored, having a self-hosted chat platform can be a game-changer—especially for families who want to keep their conversations private and under their own control. Matrix-Synapse (the server) paired with Element (the client) gives you a modern, secure, and fully decentralized messaging system. Even better: if you’re already running Unraid at home, you can have a Matrix-Synapse + Element stack up and running in under an hour. Here’s why it’s worth the effort, and how to do it.

Why Matrix + Element?

1. True End-to-End Encryption

Element supports Matrix’s built-in E2EE, so every message, file, or voice note is encrypted on your device before it travels over the network—and only your intended recipients can decrypt it. No more wondering whether Big Tech or malicious actors could be reading your chats.

2. Complete Data Ownership

With a self-hosted Synapse server, you control every bit of stored data: message history, media uploads, and user accounts. There’s no third-party retention policy or backdoor—your family’s conversations stay in your hands.

3. Cross-Platform & Future-Proof

Matrix is an open standard with implementations on every major platform (iOS, Android, Windows, macOS, Linux, even web). As new clients and bridges appear, you can integrate SMS, IRC, Discord, or even Slack into your very own home chat network.

4. Decentralization & Federation

You don’t need to run a single massive server. If you choose, you can federate with other Matrix homeservers—family members at different addresses, friends in other countries, or community servers—while still keeping your primary data private.

5. Family-Friendly Features

Element’s group rooms, file-sharing, voice/video calls, and simple UI make it approachable for kids, parents, and grandparents alike. You get the modern bells and whistles (stickers, emojis, threaded replies), without sacrificing privacy or control.

Below are the instructions to host your own, but even if you don’t want to do that you can still get a free account on https://matrix.org

Quick Setup on Unraid

Prerequisites

1. Unraid server with Docker and Community Applications plugin installed
2. Domain name (e.g. chat.yourdomain.com) pointed via DNS to your home IP (or dynamic DNS)
3. (Optional but recommended) Let’s Encrypt or similar reverse-proxy for TLS

Step 1: Install a Reverse Proxy

1. Go to the Apps tab in Unraid, search for “Nginx Proxy Manager”, and install it.
2. In the container’s Web UI, add a new proxy host:
   • Domain Names: chat.yourdomain.com
   • Scheme: http
   • Forward Hostname / IP: synapse (we’ll create this next)
   • Forward Port: 8008
   • Enable Websockets Support and Block Common Exploits.
   • Under SSL, request a new Let’s Encrypt certificate for chat.yourdomain.com.
3. Another option is to use something like Cloudflare

Step 2: Deploy Matrix-Synapse

1. In Apps, search for “Synapse” (look for the official Matrix Synapse container).
2. Click Install and set the following template variables: envCopyEditSYNAPSE_SERVER_NAME=chat.yourdomain.com SYNAPSE_REPORT_STATS=no
3. Map your host folders: bashCopyEdit/config → /mnt/user/appdata/synapse
4. Expose the internal port 8008 (Synapse HTTP) but don’t publish it on the host—Nginx will handle the outside traffic.
5. Finish install and start the container. It will generate a homeserver.yaml in /config and register the domain.

Step 3: Create Your First User

bashCopyEdit# Open a terminal to your Unraid host:
docker exec -it synapse python3 -m synapse.app.homeserver \
    --config-path /config/homeserver.yaml \
    register_new_matrix_user https://localhost:8008 \
    your_username your_password --admin

This creates an admin user (you can create more for family members later).

Step 4: Install Element Web

1. In Apps, search for “element-web” or “Element Matrix”.
2. Install with settings: envCopyEditSYNAPSE_URL=https://chat.yourdomain.com
3. Map volumes: bashCopyEdit/config → /mnt/user/appdata/element-web

Step 5: Configure Nginx for Element

In Nginx Proxy Manager, add a second Proxy Host:

• Domain Names: element.yourdomain.com (or reuse the same host if you prefer a subpath)
• Scheme: http
• Forward Hostname / IP: element-web
• Forward Port: 80 (Element’s default web port)
• Enable SSL with Let’s Encrypt, and make sure HSTS is on.

Step 6: Test & Invite Your Family

1. Visit https://chat.yourdomain.com (Element will redirect you if you chose a subpath).
2. Log in with the admin account you just created.
3. Create rooms for “Family Chat,” “Photos,” or “Video Calls.”
4. Invite new users by sharing their username (@alice:chat.yourdomain.com). They can sign up directly via the web UI.

Tips for Smooth Operation

• Backups: Regularly back up /mnt/user/appdata/synapse and your TLS certificates.
• Updates: Use Unraid’s built-in Docker update tool. Always test in a staging container if possible.
• Bridges: Explore bridges to SMS or IRC so family members can join from platforms they’re already comfortable with.
• Mobile Apps: Encourage everyone to install Element on their phones (iOS / Android) for push notifications and offline access.
