Privacy Policy
How ComfyUI Workflow Lab upholds a strict client-side architecture with zero workflow uploads and zero tracking cookies.
1. Client-Side Privacy Architecture: Zero File Uploads
At ComfyUI Workflow Lab, our highest architectural priority is local data sovereignty. We believe software tools should not demand your proprietary workflows or image assets simply to inspect dependencies or generate setup scripts.
When you use our utilities:
- Missing Node Auto-Resolver: Dropping a Civitai PNG, ComfyUI canvas JSON, or A1111 file reads binary chunks directly in memory using the browser's
FileReader. The PNGtEXt/iTXtdecoder runs exclusively in your browser tab. - Zero Network Transmission: Neither your image pixels, prompt strings, checkpoint filenames, nor custom node configurations are ever uploaded to, intercepted by, or stored on our servers.
- Zero-to-Hero Bootstrapper: Generates setup scripts dynamically in memory using client-side string synthesis. Your choices remain on your machine.
F12), inspect the Network tab, and drop any file into the resolver. You will see zero outbound HTTP POST or PUT requests containing your file payload.
2. Server & CDN Logging
This website is statically deployed and served via Cloudflare's global edge network (Cloudflare Pages):
- Edge Network Logs: Standard web server connection data (such as requesting IP address, HTTP request method, URL path, HTTP status code, referrer URL, and browser User-Agent string) may be processed temporarily by Cloudflare for edge routing, CDN caching, DDoS mitigation, and security anomaly detection.
- Cloudflare Web Analytics: We utilize Cloudflare's privacy-focused, cookie-free Web Analytics. This service collects aggregate operational metrics (such as page visits and country-level geographic distribution) without setting tracking cookies, without persistent user fingerprinting, and without tracking users across third-party websites.
3. Local Browser Storage (localStorage)
We do not use server-side sessions or database user profiles. We utilize the browser's localStorage API solely for client-side user experience preferences:
-
theme: Stores your visual theme preference ("dark"or"light") to prevent bright screen flashes upon subsequent page loads.
This value is stored entirely on your local device and can be cleared at any time through your browser's "Clear Site Data" or "Clear Browsing History" settings.
4. Third-Party Services & External Links
ComfyUI Workflow Lab provides direct outbound links to external developer ecosystems, including:
- HuggingFace (huggingface.co) for model weights and GGUF quantizations.
- Civitai (civitai.com) for community showcases, LoRA references, and base checkpoints.
- GitHub (github.com) for custom node repositories and ComfyUI extensions.
- Yellorn Ecosystem (yellorn.com and hoangyell.com).
When you click an external link, you leave our site. We do not control and are not responsible for the privacy practices, cookie policies, or content of third-party platforms.
6. Data Retention & User Rights
Because our application architecture is static and client-side:
- We do not maintain a database of user profiles, email lists, or passwords.
- We do not store your dropped workflow JSONs or PNG images.
- There is no central database containing your personal identity to access, rectify, or erase under GDPR or CCPA.
If you have questions regarding edge CDN logs or security telemetry, you may reach out directly via the contact details below.
7. Children's Privacy
ComfyUI Workflow Lab is a technical utility and educational resource for software engineers, machine learning practitioners, and digital creators. The site is not directed to children under 13 years of age, and we do not knowingly collect personal information from children.
