Launch Hub aims to make its calculators usable by people working with keyboards, screen readers, zoom and high-contrast settings. A tool that cannot be reached without a mouse is a tool that fails its own purpose. We state it plainly here.
Accessibility Commitment
We treat accessibility as a requirement of each calculator rather than a final polish pass. That means a labelled input, a readable result and a logical path through the page for someone who never uses a pointing device.
Where we change a layout or add a control, we check the change with assistive technology and with keyboard-only navigation.
Consider a compounding calculator used with a screen reader: the label, the unit hint and the result must be announced in an order that makes the arithmetic understandable without seeing the page.
Compliance Standards
We work toward WCAG 2.1 Level AA, covering requirements that content be perceivable, operable, understandable and robust. Conformance is a target we test against rather than a certificate we claim to hold, and we describe it that way deliberately.
Pages use semantic headings, ARIA landmarks where they help and native form controls wherever possible.
A unit converter, for example, should state the measurement system in text beside the field so that the information survives when a reader cannot distinguish a coloured badge.
Accessible Features
Decorative imagery carries empty alternative text, informative diagrams are described in nearby prose, and text can be enlarged to 200 percent without losing the result.
Imagine a freight estimator whose result appears below the fields: the result is also exposed as text with a clear heading.
- A high-contrast display option improves legibility without changing the calculated values or the layout logic.
- Skip links let keyboard and screen-reader users move straight to the calculator instead of stepping through every navigation item.
- Each input has a persistent label and a short unit hint, and validation failures are announced rather than shown only as a red outline.
Keyboard Navigation
Interactive elements follow the order in which they appear, and focus is visible on every control including the calculate button and any reset link. Where a tool adds a shortcut, the standard Tab and Enter behaviour still works unchanged.
No control traps focus, and we test the main tools with common screen readers and plain keyboard navigation.
A percentage calculator with three inputs, for instance, can be filled, submitted and read in sequence, with the result reachable as soon as it is produced.
Screen Reader Support
Headings follow a sensible hierarchy from the page title down to section labels, dynamic results are announced through a live region, and tables or lists are given headers that make their values meaningful when read aloud.
Compatibility is checked across current browsers and the assistive tools most readers are likely to have.
- Worked examples are written as prose with the units spelled out, so a reader hears kilograms rather than a bare abbreviation.
- Complex symbols in a formula are accompanied by a spoken equivalent, keeping the calculation understandable when the visual notation is not visible.
Trademark Notice
Tool names on this site are functional descriptions and are not checked against trademark registers before publication.
Readers who adopt any wording from our pages for a product or publication take on the whole of that check themselves.
This statement sits alongside our Terms of Service, which governs use of the tools, so that accessibility expectations and usage conditions are described in the same terms rather than contradicting each other. The same limit applies on every page. Hand-checking settles most doubts.
Governing Law
This statement operates under the law of the jurisdiction in which the site operator is established, and courts of that jurisdiction handle accessibility-related disputes. Nothing here reduces a protection that local law makes mandatory for a reader.
Severability preserves the remaining wording if a clause is found unenforceable, and no choice-of-law term is intended to remove a right that cannot be waived.
Editorial Review
The author reviews this statement periodically against the current state of the site, since a new widget or a redesigned form can introduce a barrier without changing any formula.
Checks happen at least quarterly and after significant interface changes, and the date at the top of this page records when the description was last verified.
Contact Us
If a calculator is hard to use with your setup, tell us through the Contact Us page or at [email protected]; we respond within two working days with what we plan to change.
