Purpose
Tools by Layna publishes calculators, comparison tools, guides, charts and downloadable resources. The aim is to make common Australian work, money, business, health, fitness, nutrition and measurement questions easier to understand. The site provides estimates and general information; it does not replace advice based on a person’s full circumstances.
How calculator pages are checked
Before publication, calculator pages are reviewed for the calculation logic, input labels, units, rounding, default values, worked examples, result wording and obvious edge cases. Higher-risk calculators are also checked against current official Australian sources where rules, rates or government settings affect the result.
- Inputs and outputs must be clearly labelled.
- Formulas and major assumptions must be explained in plain language.
- Results must not be presented as guaranteed outcomes.
- Limitations must appear close enough to the calculator to be useful.
- Mobile input, keyboard behaviour and result visibility must be tested.
How guides and resources are checked
Supporting articles are reviewed for factual consistency with the linked calculator, useful examples, clear related links, source relevance and repeated or templated wording. Printable resources are checked against the calculator or reference table they support.
Sources and changing information
Where a page depends on Australian tax, superannuation, employment, government-payment or lending settings, official government or regulator sources are preferred. Pages that depend on changing figures should show the relevant financial year or review date. Users should confirm the current official position before making a legal, tax, medical, employment or financial decision.
Corrections and updates
When an error is found, the affected calculation or wording should be corrected promptly. Material changes should update the visible review date and structured-data modification date. A correction should not be hidden by adding vague wording around an incorrect result.
Professional limitations
Tools by Layna does not provide personal medical, dietetic, legal, tax, employment, lending or financial advice. A calculator can estimate, compare and stress-test a scenario, but it cannot establish eligibility, diagnose a condition, interpret a contract or assess every relevant fact.
Content responsibility
Tools by Layna is responsible for publishing and maintaining the site. A named professional reviewer is only shown where that person has actually reviewed the relevant content and their role can be stated accurately. The absence of a named reviewer does not change the need for clear sources, honest limitations and accurate calculations.
