Fibonacci Calculator is a static website. The Fibonacci tool runs in your browser and does not send your inputs to our servers for calculation.

Like most websites, our hosting and analytics partners may process technical data such as IP address, browser type, and pages viewed.

We do not ask you to create an account to use the calculator.

If you email us, we receive the address and message content you choose to send.

Server logs maintained by our host may include standard request metadata used for security and performance.

We may use privacy-focused analytics to understand aggregate traffic. Where cookies are used, you can control them through your browser settings.

Third-party share links open external sites with their own policies.

Privacy questions may be sent to the support email listed on the contact page.
