Does the tool fetch or scan my website?

No. This browser-only tool works from the values you enter and does not request the submitted URL.

Are my inputs sent to AHANIX?

No. Generation happens in the current browser tab. Only non-content usage events, such as the tool category and whether a result was produced, may be measured.

Is the result guaranteed?

No. It is a practical automated result or drafting aid with the limitations explained on the page.

Do I have to request an email report?

No. The basic result is available on the page without marketing consent. Eligible tools offer an optional report.

What should I do before publishing the result?

Review it against the real website, business activity and current platform or legal requirements, then test any implementation.
