Contact GoldenSpiral

GoldenSpiral is a small, independent, ad-supported site — there is no support team standing by, but a real person reads what comes in to support@fibonnaci.com.

A few things this address is genuinely useful for: a calculator that gave you a result you think is wrong (say which tool — the Fibonacci calculator, golden ratio calculator, modular scale generator, golden spiral calculator, Lucas number calculator, or golden ratio grid— and the values you entered); a calculator you wish existed on the site; an out-of-date fact, broken link, or factual error in the blog, learn section, or the museum; or a bug in how a page looks or behaves on your device.

There’s no fixed response time to promise, and no ticket number or live chat — email is read and handled as it comes in. This isn’t the place for general math tutoring or homework help beyond what a specific tool or article already covers — for that, a teacher or a dedicated Q&A community will do better than we can. GoldenSpiral provides general educational calculators and reference content, and isn’t affiliated with any university, museum, or standards body.

Before writing in about a tool result, it can help to double-check the numbers you entered — a term index outside a tool’s supported range, a negative length, or a mistyped ratio is the most common source of a surprising answer or an error message. If it still looks wrong after that, that’s exactly the kind of message worth sending.
