Allin1Tool is a small operation run by Klig Technologies. There's no newsroom and no editorial board, so this page just describes the real process. If you find a mistake, the fastest fix is to email us. Corrections get priority over new features.
Who writes the pages
The tool descriptions, how-to steps and explanatory articles are drafted with AI assistance and then edited by the person maintaining the site. We don't claim medical, legal or financial credentials, and you shouldn't treat anything here as advice from someone who has them. Where a page carries a “last updated” date, that date is the last time the page was genuinely revised.
Where the formulas come from
Every calculator implements a published, named method. We didn't invent any of them. The page for each tool states which one it uses, so you can check the result against the source yourself. Examples:
- Body mass index uses the World Health Organization definition and its adult classification bands.
- Basal metabolic rate uses the Mifflin-St Jeor equation.
- Body fat percentage uses the US Navy circumference method, in its metric form.
- Estimated due date uses Naegele's rule from the last menstrual period.
- Loan repayments use the standard reducing-balance annuity formula; SIP and recurring deposit projections use annuity-due compounding, which is the convention Indian providers quote.
- Unit conversions use the exact definitional factors (one pound is 0.45359237 kg, one inch is 2.54 cm, one mile is 1609.344 m), computed without pre-rounding.
Some figures are rules of thumb, not standards, and daily water intake is the clearest example. Where that's the case, the page says so plainly instead of dressing it up as a guideline.
What is checked automatically
The repository carries a test suite that runs against the content and the site structure. It isn't a proofreader. What it catches is a specific set of mechanical failures:
- sentences or headings repeated across more than a couple of tool pages
- duplicate or truncated page titles and meta descriptions
- internal links that 404 or hop through a redirect
- pages with no heading, a broken heading order, or placeholder text left behind
- duplicated FAQ questions and answers
- every route returning the status code it should, with a correct canonical URL
Calculator outputs are checked against worked examples by hand when a formula changes. They aren't independently audited, and we don't claim they are.
What we do not do
We don't run a scheduled review cycle, we don't have a testing lab, and no page here has been reviewed by a doctor, an accountant or a lawyer. Earlier versions of this page implied otherwise. That was wrong, and it has been removed.
Corrections and limits
Results are estimates. They exclude the fees, taxes, individual circumstances and rate changes that decide real outcomes. Before acting on anything consequential, check with someone qualified. See the full disclaimer. When we correct something material, the page's last-updated date moves.
