When searching for a "StreamFab license," you will see two radio buttons during checkout. Here is the brutal truth about both.
A StreamFab license gives you the technical right to use the software, but it does not override the terms of service of streaming platforms. Downloading content from Netflix, Hulu, etc., may violate those platforms' terms. Always use such tools for personal, offline viewing of content you are already entitled to access, and respect copyright laws in your jurisdiction.
The most important thing to understand about StreamFab is that there is no single universal "_lifetime" license. Instead, the software operates on a modular basis. The license is divided into specific modules that correspond to different streaming services.
