Good to know
What can I download with FluxGrab?
FluxGrab is a general-purpose tool for saving media you own, created, or have explicit permission or a license to download — for example your own uploads, content released under permissive licenses, or files you're authorized to keep for offline use.
Is this legal?
The tool itself is legal. You are responsible for how you use it. Please only download content you have the right to, and always respect the terms of service of the sites you use and applicable copyright law. See our Terms.
Do I need an account?
No. The free plan works without an account. A Pro license simply unlocks higher quality and batch features on your device.
Is Pro really one-time?
Yes. $19.9 once, lifetime license with free updates. No recurring charges.
What's the difference between the web version and the desktop app?
The web version is a quick, install-free way to grab up to 720p. The desktop app is faster, supports 1080p/4K, batch downloads, and runs entirely on your own machine.
Can I get a refund?
Yes — see our Refund Policy. If FluxGrab doesn't work for you, contact us within the stated window for a refund.
