About na.to

na.to is a collection of free tools where each subdomain is one tool: salary and tax calculators, unit and colour converters, short browser games, and articles on drama, animation, everyday life and money, in Korean, English and Japanese.

Principles

• No sign-up. Every tool works the moment it opens.
• Your data stays with you. Inputs are processed in your browser and never sent to our servers.
• Estimates, not advice. Results come from general formulas and are for reference.
• Funded by advertising. Google AdSense ads keep everything free.

About the work pages

Articles on dramas and animation are unofficial fan-written structural commentary. They do not reproduce plots, quote dialogue or display images. Requests from rights holders are handled promptly.
