    question: "Is Lumina Convert 100% free at all times?",
    answer: "Yes, absolutely! Lumina Convert is entirely free, with no hidden subscriptions, trial caps, watermarks, or locked files. Every features, including batch conversions, high quality resolution configurations and dynamic on-device GPU acceleration, is active from the moment of installation.",
  },
  {
    id: "faq-1",
    cat: "security",
    question: "Does my data or files get uploaded to any internet servers?",
    answer: "No, never. Lumina Convert operates as an 'offline-first' software. 100% of the conversions and encodings process locally in your system. This makes our framework highly trusted by healthcare teams (HIPAA guidelines) and legal professionals bound under rigid client-non-disclosure policies.",
  },
  {
    id: "faq-2",
    cat: "formats",
    question: "How many formats can Lumina Convert encode?",
    answer: "Lumina supports over 200+ distinct multimedia extensions. You can convert documents (PDF, DOCX, XLSX, CSV), rich graphic layouts (WebP, SVG, PNG, TIFF, JPG), high frame rate films (MP4, MKV, MOV, GIF), and lossless studio audios (WAV, FLAC, Standard MP3).",
  },

    id: "faq-3",
    cat: "installation",
    question: "Which platforms does the installer require?",
    answer: "Our standard installer supports Windows 10 and Windows 11 (both 64-bit platforms). It integrates pre-compiled architecture assemblies for NVIDIA CUDA, OpenCL cores, and standard CPU multithreading models out-of-the-box, ensuring optimal performance across different hardware configurations.",
  },
  {
    id: "faq-4",
    cat: "security",
    question: "Can I use Lumina Convert on confidential government datasets?",
    answer: "Yes. Because Lumina Convert holds zero networking permission layers on default execution files, it is impossible for compiled data structures to telemetry to external cloud coordinates. It safe-guards strict compliance acts.",
  },
  {
    id: "faq-5",
    cat: "installation",
    question: "How do I trigger folder watch automation channels?",
    answer: "In the desktop settings panel, select 'Watch Directories'. Link your target directories (e.g. ~/Downloads/Inputs). Select a standard encoding profile (e.g., PDF to Lossless WebP). When new items enter that folder path, Lumina Convert triggers automatically behind-the-scenes using minimal background system processing.",
