Accessibility Statement
Birthday Compatibility is committed to making our website and tools accessible to everyone, regardless of ability or disability. Here is what we do, what we aim for, and how you can help us improve.
Last updated: April 13, 2026
Our Commitment
We believe that everyone deserves access to meaningful self discovery tools. Accessibility is not an afterthought for us. It is a core design principle that shapes how we build our website, write our content, and develop our calculators. Our goal is to ensure that every visitor, including those who use screen readers, keyboard navigation, magnification software, or other assistive technologies, can fully use and benefit from everything we offer.
We strive to conform to the Web Content Accessibility Guidelines (WCAG) 2.1 at the AA level, which is the internationally recognized standard for web accessibility. While we may not achieve perfect conformance on every page at all times, we are committed to continuous improvement and treating accessibility as an ongoing priority rather than a one time task.
Accessibility Features on Our Website
Here are the specific measures we have taken to make Birthday Compatibility accessible.
Keyboard Navigation
All interactive elements on our website, including calculator inputs, buttons, dropdown menus, and FAQ accordions, can be accessed and operated using only a keyboard. You do not need a mouse to use any feature on this site.
Screen Reader Compatibility
Our pages use semantic HTML5 elements such as article, section, nav, aside, and main to provide meaningful structure for screen readers. Form inputs have associated labels, interactive elements include ARIA attributes where appropriate, and decorative elements are marked as hidden from assistive technology.
Readable Text and Contrast
Body text is set at a minimum of 17 pixels with a line height of 1.72, ensuring comfortable reading at various screen sizes. Our color palette maintains sufficient contrast ratios between text and background elements to meet WCAG AA standards. We avoid relying on color alone to convey information.
Responsive Design
Every page on our website is fully responsive and adapts to different screen sizes, from large desktop monitors to mobile phones. Content reflows properly when the browser is zoomed up to 200%, ensuring that users who need magnification can still access everything without horizontal scrolling.
Semantic Structure and Headings
All pages follow a logical heading hierarchy (h1 through h3) so that screen reader users and keyboard navigators can quickly jump between sections. We do not skip heading levels or use headings purely for visual styling.
Form Accessibility
All form fields in our calculators and contact form have visible labels, descriptive placeholders, and clear error messages that explain what needs to be corrected. Required fields are clearly indicated, and form validation messages are announced to screen readers through ARIA live regions.
Fast Loading and Lightweight Pages
Our pages are built with system fonts, minimal CSS, and no external JavaScript libraries. This keeps page sizes small (typically under 50KB) and load times fast, which benefits users on slow connections, older devices, or data limited plans.
Descriptive Link Text
We avoid vague link text like "click here" or "read more." Every link on our site uses descriptive text that makes sense out of context, so screen reader users navigating by links can understand where each link leads without needing surrounding context.
No Flashing or Autoplay Content
Our website does not contain any flashing, strobing, or rapidly animating content that could trigger seizures or cause discomfort. We do not autoplay audio or video. The only animations on the site are subtle, slow transitions that do not impact usability.
Client Side Processing for Privacy
Our calculators process all data locally in the browser without any server communication. This means users of assistive technology do not encounter authentication walls, loading delays from server requests, or CAPTCHAs that can be difficult to complete with screen readers.
The Four Principles We Follow
WCAG 2.1 is built on four foundational principles known as POUR. These principles guide every design and content decision we make.
Perceivable
Information and interface elements must be presentable in ways that all users can perceive, whether through sight, hearing, or touch.
Operable
Interactive elements must be operable through multiple input methods including keyboard, mouse, touch, and voice control.
Understandable
Content and interface behavior must be clear, predictable, and easy to comprehend for users of all cognitive abilities.
Robust
Content must be built with standard, well structured code that works reliably across a wide range of browsers, devices, and assistive technologies, including those that may be developed in the future.
Plain Language Commitment
Accessibility goes beyond technical implementation. It also means making sure the words on the page are understandable. We write all of our content in clear, plain language and avoid unnecessary jargon. When numerological terms are used, we define them in context so that readers do not need prior knowledge to understand what they are reading.
Our content is written to be comprehensible to a general adult audience. We use short sentences where possible, break complex ideas into smaller sections, and structure every page with clear headings so that readers can scan and find what they need quickly.
Known Limitations
We are honest about the fact that our website may not be perfectly accessible in every situation. Here are the limitations we are currently aware of and working to address.
Some older browsers or very outdated versions of assistive technology may not fully support the CSS and HTML features used on our site. We optimize for modern browsers and current versions of popular screen readers such as NVDA, JAWS, and VoiceOver, but cannot guarantee compatibility with all legacy software.
Our compatibility score visualization uses an SVG ring animation. While the percentage and verdict text are accessible as standard text elements, the visual animation itself is purely decorative and is marked as hidden from assistive technology. All information conveyed by the animation is also available in text form.
As we add new content and features over time, there may be brief periods where newly published pages have not yet been fully tested for accessibility. We aim to test all new content within one week of publication and correct any issues found.
If you encounter any accessibility barrier that is not listed here, please let us know so we can add it to our improvement roadmap.
Assistive Technologies We Test With
We test our website with the following tools and technologies to verify accessibility compliance.
Screen Readers
NVDA on Windows, VoiceOver on macOS and iOS, and TalkBack on Android. These cover the most widely used screen reader platforms.
Keyboard Only Navigation
All interactive elements are tested for full keyboard operability, including tab order, focus visibility, and activation via Enter or Space keys.
Browser Zoom
All pages are tested at 200% zoom to ensure content remains readable and functional without horizontal scrolling or overlapping elements.
Contrast and Color Testing
Color contrast ratios are verified using automated tools to ensure text meets WCAG AA minimum contrast requirements of 4.5:1 for normal text and 3:1 for large text.
Automated Accessibility Scanners
We use tools such as Lighthouse, axe DevTools, and WAVE to identify and resolve common accessibility issues across all pages.
Our Ongoing Efforts
Accessibility is not a checkbox we mark once and forget. It is an ongoing commitment that shapes how we build, write, and maintain this website. Here is what we are actively doing to maintain and improve accessibility over time.
All new pages and features are built with accessibility in mind from the start, not retrofitted after launch. Existing content is reviewed periodically for accessibility compliance as part of our regular content update cycle. We monitor web accessibility standards for updates and adopt new best practices as they become available. Feedback from users with disabilities is prioritized and acted upon promptly. Our development process includes accessibility testing as a required step before publication.
Report an Accessibility Issue
If you experience any difficulty accessing our website, using our tools, or reading our content, we want to hear from you. Your feedback directly shapes our improvement efforts and helps us make the site better for everyone.
When reporting an issue, it is helpful (but not required) to include the page URL where you encountered the problem, a brief description of the issue and what you were trying to do, the assistive technology or browser you were using, and your preferred method of contact for our response.
Reach us at mail@birthcompatibility.com or through our Contact page. We aim to acknowledge all accessibility reports within 48 hours and resolve issues as quickly as possible.
Third Party Content
Our website may occasionally embed or link to content from third party sources. While we strive to only link to accessible external resources, we do not have control over the accessibility of third party websites. If you encounter accessibility issues on a linked external site, we encourage you to contact that site directly. If you believe a link on our site leads to an inaccessible resource, please let us know and we will evaluate whether an accessible alternative is available.
Standards and Guidelines We Reference
Our accessibility practices are informed by the following standards and resources. The Web Content Accessibility Guidelines (WCAG) 2.1, published by the World Wide Web Consortium (W3C), which provides the internationally recognized framework for web accessibility. The WAI-ARIA (Accessible Rich Internet Applications) specification, which provides additional semantic information for dynamic content and interactive elements. The HTML Living Standard, which defines the correct use of semantic elements that assistive technologies rely on to interpret page structure.
