Send calculation errors, source corrections, unclear wording, broken links, privacy requests, and editorial questions to the email below. Useful reports identify the affected page, input, formula, public-data record, or claim and explain the result you expected.

Useful correction format

• Page URL and the section that needs review.
• The exact wording that seems unclear, outdated, or incorrect.
• An official source link when the correction depends on a public rule or safety boundary.
• Whether the issue affects an input, formula, source role, displayed result, or limitation.

Response scope

We can review calculation and editorial corrections, source updates, and general product suggestions. We cannot provide a mortgage quote, tax return, legal opinion, investment recommendation, access permission, catch forecast, or safety guarantee.

Product requests

Good requests name the live tool, the decision being made, the missing input or output, and the official source that may improve the result. Requests are evaluated for fit with APT, MOVE, or FINVECTOR before publication.
