Parts the app uses

Your files stay on your computer

Your pictures, videos and settings stay on your computer. The app itself has no account, no tracking and no usage statistics. All processing runs on your own graphics card.

AI Q&A is the one part that sends something you write: once you open it, your questions go to Mintlify. Your files never go with them.

When the app goes online

The app connects to the internet only for these things:

What	When	Where to
Update check	At every start, unless Check for updates at start is off; and when you click Check for updates.	GitHub, or the mirror site you chose under GitHub access.
Update download	Only when you click Update now, or run `--update` or `--edition`.	The same.
Measuring mirror sites	When Mirror sites, the fastest one is chosen, or you click Measure the sites.	The eight known mirror sites.
DLSS-NR-on-AMD	Radeon edition only: the look-up of its newest release, and the installer download when you click the button.	That project's release page on GitHub, or the chosen mirror site.
AI Q&A	Only after you click Ask AI. Once opened, the panel stays loaded until you close the app.	Mintlify, which writes the answers, and hCaptcha, Mintlify's bot check. Details
MCP jobs by web address	Only when the MCP server is on and a client sends a job that names its picture or video by a web address.	That address. Details

Runs from the command line with --headless or --process never check for updates on their own.

Buttons such as Documentation, Download driver and Report a problem open a page in your browser. Report a problem fills in the app version and your graphics card in GitHub's form; nothing is sent until you submit it.

AI Q&A in the app

Ask AI in the top bar opens AI Q&A in a panel beside the picture. It answers questions from this documentation. Mintlify provides it, not the app. AI Q&A

Nothing starts before you open it. The app starts Microsoft Edge WebView2, which draws the panel, only at your first click on Ask AI. Until then, nothing is sent.
What goes to Mintlify. What you type goes to Mintlify, which writes the answer, so leave out anything private. The line at the top of the panel says so too. Mintlify also receives usage events from the panel, such as when it opens. To keep bots out, Mintlify checks questions with hCaptcha, which the panel loads from hCaptcha's servers.
What stays here. The app never sends your pictures, videos, settings or library. If the panel offers to attach a file, whatever you attach or paste there goes to Mintlify too.
What the panel keeps. Its cookies and storage, in %LOCALAPPDATA%\VRChatDLSS5Cam\webview2, or in webview2 inside the folder given with --data-dir. Your conversation lasts until you close the app. With the app closed, you can delete that folder; the app makes a new one at the next opening.
What the log notes. When the panel opens and closes, any error it meets, and the HTTP status and the length of each answer. Never your questions or the answers' text. A link you open from an answer is logged with its address, like every page the app opens.

Without the Microsoft Edge WebView2 Runtime, and in the Linux package, Ask AI opens the AI Q&A of this site in your browser instead. Then AI Q&A on this site applies.

The MCP server

The MCP server is off until you turn it on. When on, it listens on your computer only and never connects anywhere by itself. A job can name its picture or video by a web address instead of sending the file; the app then downloads it from there. Other computers can reach it only after you set Reach to Local network and give them a key. MCP

This site

These pages load nothing from other servers on their own: no fonts, no scripts, no tracking. The one exception is AI Q&A, and only when you reach for it. The theme and language you choose are kept in your browser only.

AI Q&A on this site

Ask AI opens AI Q&A, which answers questions from these pages. Mintlify provides it, not this site.

Nothing from Mintlify loads with the pages. It starts to load when you point at Ask AI or move to it with the keyboard, in the top bar or at the end of the search results, so that it is ready when you click. What you type goes to Mintlify, which writes the answer, so leave out anything private. Mintlify also receives usage events from the panel, such as when it opens; this site asks it to leave out the page's address. To keep bots out, Mintlify checks questions with hCaptcha, which the panel loads from hCaptcha's servers. In this browser tab, the panel keeps a reference to your conversation, so that a follow-up question continues it.

Licence

The app's licence statement, as it stands in the README:

MIT (see LICENSE). Third-party components and the NVIDIA notice are listed in THIRD_PARTY_NOTICES.md. This project is not affiliated with VRChat Inc. or NVIDIA Corporation.

The full texts: LICENSE and THIRD_PARTY_NOTICES.md. Both are also in the app's folder. The third-party notices come in four languages: next to the English file are translations into Chinese, Japanese and Korean (THIRD_PARTY_NOTICES.zh-CN.md, .ja.md and .ko.md), where the English file is the one that counts. About → Third-party notices opens the one in the interface's language.

Parts the app uses

Part	Licence
NVIDIA DLSS 5 runtime (`nvngx_dlssnr.dll`)	NVIDIA's software under NVIDIA's terms, not covered by the app's MIT licence. GeForce edition: two builds; Radeon edition: one, for DLSS-NR-on-AMD's installer.
NVIDIA DLSS SDK (NGX, `nvngx_dlss.dll`)	NVIDIA RTX SDKs License Agreement.
NVIDIA Optical Flow SDK (interface headers)	MIT.
AMD FidelityFX SDK (`amd_fidelityfx_dx12.dll`, Radeon edition)	MIT.
Spout2	BSD 2-Clause.
Dear ImGui	MIT.
dlss5-bridge	MIT.
ONNX Runtime	MIT.
DirectML	Microsoft's DirectML licence, which allows shipping it with apps.
Depth Anything V2 Small	Apache License 2.0.
libwebp	BSD 3-Clause.
Microsoft Edge WebView2 SDK (built into the app, for the AI Q&A panel)	BSD 3-Clause. The WebView2 Runtime itself is Microsoft's and is not shipped with the app.
Lucide icons	ISC; the icons derived from Feather also MIT.
Direct3D shader compiler (`d3dcompiler_47.dll`, Linux package)	Microsoft Software License Terms for the Windows SDK.

DLSS-NR-on-AMD is not included. It is a separate project under its own terms, which allow personal, non-commercial use and no redistribution. The Radeon edition downloads its installer from that project's release page only when you ask.

Mintlify's AI Q&A is not included either. The panel loads it from Mintlify's servers when you first open it.

This site uses Lucide icons under the ISC licence; the licence text is in assets/licenses/lucide-LICENSE.txt.
