No. Every tool runs locally in your browser. The JSON you paste, the colors you pick and the code you generate never leave your device.
What does the Pro Pass include?
A one-time payment of $1.99 USD removes ads and unlocks advanced exports such as Tailwind classes, SCSS variables and design tokens, plus JSON key sorting.
Can I use the generated code commercially?
Yes. The code you generate is yours to use in personal and commercial projects without attribution.
