Licence and source
FluidEQ is free software, and the download is free. How the licence works, where the source is, and who is behind it.
FluidEQ is free software under the GNU General Public License v3.0 or later.
FluidEQ is free, and FluidEQ Plus is a membership for scenes and online features, not a licence. Nothing on this site, in the app or in the Plus terms restricts what you may do with the software — the freedoms to use, study, modify and redistribute come with every copy and cannot be taken back.
This program is distributed in the hope that it will be useful, but without any warranty; without even the implied warranty of merchantability or fitness for a particular purpose. See the licence text for details.
Where the law where you live does not allow a disclaimer of that kind, the law where you live applies. Nothing here removes a right you have as a consumer, and nothing here excludes liability for death or personal injury caused by negligence.
Building it yourself
An option rather than a formality. The installer published on GitHub spares you the toolchain; building it yourself gives you the same application.
- What you need
- Windows 10 or 11, Node.js 20 or newer with pnpm, and Visual Studio 2022 with the “Desktop development with C++” workload.
- What you run
- Clone the repository,
pnpm install, thenpnpm package— which writes an installer intorelease/build, with the engines bundled exactly as they are in the published one. - What differs
- Nothing in the application. Neither your build nor the published installer is code-signed for Windows yet, so SmartScreen warns about the publisher either way, and every copy, yours included, installs an update only when it carries the maker’s signature. FluidEQ Plus is a service reached with an account, and works the same in both.
Name and logo
The GPL covers copyright, not trade marks. The FluidEQ name and the logo — the teal wave on a dark rounded square — are not licensed with the code and stay reserved. Anyone may take the source and build on it; a fork must not use the name or the logo to identify itself. The notice lives in TRADEMARK.md.
Who is behind it
- Made and supported by
- FluidEQ is written and supported by Ivan Carmenates Garcia. Questions and anything else: support@fluideq.com. An email reaches a person, not a queue.
- Plus payments
- FluidEQ is free, and nothing is sold on this site. A FluidEQ Plus membership is joined inside the app and paid on Buy Me a Coffee, in your browser, with the email of your FluidEQ account: Buy Me a Coffee takes the payment, and FluidEQ never sees your card.
