Compatibility comes first
A product must match the requested task, operating system, and physical disc type before it can rank. Physical UHD Blu-ray playback, UHD ripping, UHD copying, and 4K video-file playback are separate capabilities.
Ranking is deterministic
Task match contributes 40 points; operating-system and disc match contribute 20; maintained editorial priority contributes 15; budget and license preferences contribute 20; a fresh official offer contributes 5. Ties go to the lower current price.
Price freshness
Only allowlisted official Leawo and CyberLink pages are monitored. A daily GitHub Actions run rebuilds this static site. Ordinary prices disappear after 72 hours without a successful check; giveaways disappear after 36 hours or at their stated deadline. A price is source-verified, not guaranteed through final checkout.
Automatic publication guardrails
USD price, known product, official HTTPS source, current-version marker, and complete offer fields are required. Coupons require an official code and scope. Giveaways require an explicit current-year product, license term, and future expiration date.
Commercial disclosure
Configured short links may be affiliate links. A fresh deal adds only five ranking points, so commission availability cannot make an incompatible product rank first.
