Most people using Midjourney for client work don’t realize their prompts are public by default. Every image you generate in the standard Midjourney Discord server is visible to every other user. Your prompts show up in the public feed. If you’re generating images for an unreleased product, a confidential client campaign, or anything you’d rather competitors not see, this is a real exposure. Stable Diffusion cloud services have different privacy characteristics, and local deployment has its own setup considerations. I’ve been using image AI tools for client work for over two years — here’s the privacy configuration that actually works.
The short answer
Midjourney’s public gallery is the most immediate privacy risk — use Stealth Mode (Pro plan required) to prevent prompts from appearing publicly. For network privacy across all image AI tools, NordVPN masks your IP and prevents session logging. For maximum privacy, self-hosted Stable Diffusion (local or on private infrastructure) with NordVPN is the strongest option. Cloud image AI services collect extensive metadata about your creative process; network-level protection addresses the most exploitable part of that exposure.
Midjourney’s privacy model
Midjourney operates largely through Discord, which creates some unusual data characteristics:
Prompt visibility. In the standard community server, all prompts and generated images are visible to other users. They appear in the main feed and are indexed by Midjourney’s website. This is by design — the community feed is a core part of the product’s identity. If you don’t want your prompts visible, you need to use Midjourney’s private server option or enable Stealth Mode.
Stealth Mode. Available on Pro plans ($60/month and above as of mid-2026), Stealth Mode prevents your prompts from appearing in the public gallery. Your images are still generated and stored on Midjourney’s servers; they just aren’t publicly visible. The distinction matters: “not public” is different from “private.”
Server-side storage. Midjourney stores all generated images and prompts server-side regardless of Stealth Mode status. This data is subject to their privacy policy, which gives them broad rights to use content for improving the model.
IP and account linkage. Midjourney ties your Discord account to a payment method and tracks your IP address. Your IP is logged with each generation request. VPN addresses this layer.
Discord’s own data collection. Using Midjourney via Discord means Discord also collects server membership data, message metadata, and device information. These are two separate data collection layers.
Stable Diffusion privacy: cloud vs local
Stable Diffusion’s privacy profile varies dramatically based on how you run it:
Cloud services (DreamStudio, Stability.ai API, Replicate, Runway). These services log your prompts, collect IP addresses, and store generated images on their infrastructure. The privacy characteristics are similar to Midjourney — better documented than Discord-based tools, but still significant server-side collection.
Self-hosted local deployment. Running Stable Diffusion locally via Automatic1111 (WebUI), ComfyUI, or a similar frontend means your prompts and generated images never leave your machine. No server-side logging. No IP collection. No data retention by a third party. This is the strongest privacy option for image AI.
Local deployment requirements: a GPU with at least 8GB VRAM runs SDXL models acceptably (RTX 3070/4060 or better). Apple Silicon Macs run SD models surprisingly well via MPS. Setup takes 30-60 minutes following the Automatic1111 or ComfyUI documentation.
Self-hosted cloud deployment. Running Stable Diffusion on a private VPS (Hetzner, Vultr, your own server) gives you control over the infrastructure. NordVPN is relevant here for securing the connection between your local machine and the remote server, particularly on public networks.
VPN configuration for image AI workflows
For cloud image AI tools, NordVPN provides:
IP masking. Your prompt requests arrive at Midjourney’s or Stability.ai’s servers from the VPN IP, not your real IP. This prevents session correlation across services and removes geographic identification from their logs.
Prompt privacy from ISP. Your ISP can see HTTPS connections to midjourney.com or api.stability.ai. They can’t see the content of those connections, but the metadata tells a story. NordVPN encrypts all traffic, so your ISP sees only connections to a NordVPN server.
Network security on shared connections. If you’re working from a coworking space or cafe, NordVPN prevents anyone monitoring the local network from seeing your AI tool usage.
Recommended NordVPN configuration for creative work:
- Enable NordLynx protocol for best performance (image generation requires sustained HTTPS connections)
- Threat Protection Pro blocks analytics scripts on creative platforms
- Server selection: pick the nearest fast server in a jurisdiction with strong creative work protections (Netherlands works well for EU users; US East Coast for US users)

FAQ
Does Midjourney Stealth Mode make my prompts private?
Stealth Mode prevents prompts from appearing in the public community gallery. Your prompts and images are still stored on Midjourney’s servers and subject to their privacy policy. It’s “not public” rather than fully private.
Can I run Midjourney through a VPN without issues?
Yes, Midjourney via Discord works normally through NordVPN. Discord occasionally presents CAPTCHAs for connections from shared VPN IPs; if this happens, switch to a different NordVPN server.
Is local Stable Diffusion better for privacy than cloud services?
Yes, significantly. Local deployment means your prompts and generated images never leave your hardware. There’s no server logging, no IP collection, and no terms of service governing use of your creative content.
Does NordVPN work for API-based image generation?
Yes. Any HTTPS traffic — including API calls to Stability.ai, OpenAI’s DALL-E API, or similar services — routes through NordVPN when it’s active. Your development machine’s API calls are also protected.
What about copyright and VPN for image AI?
VPN doesn’t affect copyright status of AI-generated images. Copyright questions for AI-generated content depend on jurisdiction and platform terms, not network configuration.
