Licence & privacy

The short version: DemRender is free, the videos you make are yours, and nothing about you or your work leaves your computer.

Licence agreement

This is the agreement you accept when you install DemRender.

DemRender - License Agreement (Freeware)
Copyright (c) 2026 Dandem. All rights reserved.

1. Free use. You may install and use DemRender on any number of computers, at
   home or at work, free of charge. Dandem may offer optional paid features
   (for example a "DemRender Pro" edition) in the future; everything in the
   free edition stays free to use under this agreement.

2. Your videos are yours. Videos, pictures and projects you make with DemRender
   belong to you. You may publish, sell and monetise them anywhere, including
   on YouTube, TikTok, Instagram, Spotify Canvas and streaming platforms, with
   no credit to DemRender required. The built-in visualizers, effects and the
   pictures in DemRender's image catalog may be used in those videos freely.
   You are responsible for having the rights to the music and pictures you
   bring in yourself.

3. Sharing. You may share the unmodified DemRender installer with others, free
   of charge. You may not sell DemRender, charge for it, or include it in a paid
   product or service without written permission from Dandem.

4. Restrictions. Except where the licenses of the third-party components allow
   it, you may not modify, decompile, reverse engineer, extract or create
   derivative works of DemRender, its code, shaders or built-in visualizers, or
   offer them as a service.

5. Third-party components. DemRender includes free and open-source software,
   such as Electron and FFmpeg. Those components are licensed under their own
   licenses, listed in THIRD-PARTY-NOTICES.txt in the "resources\licenses"
   folder of the DemRender installation. Nothing in this agreement limits the
   rights those licenses give you.

6. Your data. DemRender does not collect or send any personal data. Your music,
   pictures and projects stay on your computer. To find updates, DemRender asks
   GitHub (github.com) for the latest version number; nothing about you or your
   work is sent.

7. No warranty. DemRender is provided "as is", without warranty of any kind. To
   the extent permitted by law, Dandem is not liable for any damage arising from
   the use of DemRender.

8. Contact: contact@demrender.com - https://demrender.com

9. If you do not agree with these terms, do not install or use DemRender.

Privacy

The app. DemRender works offline. It has no account, no analytics and no tracking. Your songs, pictures and projects are read from and saved to your own computer only. To find updates, it asks GitHub whether a newer version of DemRender has been published — GitHub sees that request like any visit to a web page (your IP address), and nothing else is sent.

This website. demrender.com is hosted on GitHub Pages and uses no cookies, no analytics and no third-party scripts. To show the newest version on the Download button, your browser asks GitHub's public API for the latest release. GitHub's own privacy statement covers both.

Email. If you write to contact@demrender.com, we use your message and address only to answer you.

Open-source notices

DemRender is not open source, but it includes open-source components, each under its own licence:

• FFmpeg — writes the video files. GNU Lesser General Public License v3. DemRender runs it as a separate program (resources\ffmpeg in the installation), which you may replace with your own build. Its complete source code and build scripts are published with every release on GitHub (see SOURCES.txt); for three years from each release we also send the source of any library compiled into it on request, at contact@demrender.com.
• Electron and Chromium — the app runtime. MIT and the Chromium licences (LICENSES.chromium.html in the installation).
• Fonts — Inter, Manrope, Archivo, JetBrains Mono, Playfair Display, Bebas Neue. SIL Open Font License 1.1.
• electron-updater and its dependencies — MIT / ISC.
