Contact us
We read every email. Tell us what you are working on, what we got wrong, or what tool you wish existed.
For all queries — corrections, suggestions, press, advertising, or general feedback — email us at contact@ah5.shop. We aim to respond to substantive queries within two business days.
What to include
To help us respond quickly:
- Corrections: include the URL of the page, the specific figure or statement you believe is incorrect, and the source that supports the correction.
- Tool suggestions: describe the question you are trying to answer and the inputs/outputs you would expect from the ideal tool.
- Bug reports: include your browser, the calculator you were using, the inputs you entered, and what happened (including any error message).
- Advertising: we accept display-ad placements only — no sponsored editorial. Include the product or service you wish to advertise and your target geography.
What we cannot help with
We are a publishing operation, not a financial, tax, legal, or immigration advisory firm. We cannot provide individual advice on:
- Personal tax filings or residency determinations
- Visa applications or immigration strategy
- Specific investment recommendations
- Estate planning or will preparation
- Disputes with remittance providers, banks, or employers
For these questions, please consult a qualified professional in the relevant jurisdiction. Our content is informational only — see our disclaimer.
