🛡️ Our License Policy
KolayDönüştür is a commercial, closed-source web service. Our own code’s npm dependencies do not include AGPL, SSPL or CC-BY-NC packages. Every PR automatically runs npm run license:check as a risk scan; if AGPL/SSPL/CC-BY-NC is detected the build fails. Our npm dependencies are under MIT, Apache 2.0, BSD, ISC or similarly commercial-friendly licenses. The separate programs and browser engines listed in the cards above (including FFmpeg) are subject to their own licenses; we use them unmodified, as programs separate from our code.
