Accessibility

This site and the app should be usable by everyone. KernBite is run by a private individual, not a company, and there is no legal duty here to make it accessible. I do it anyway, and this page records what has been done and where it still falls short.

What I measure against

My yardstick is the Web Content Accessibility Guidelines version 2.2, level AA, and for the app additionally Apple's and Google's requirements on labels, tap targets and text sizes. I expressly do not invoke a legal duty that does not apply here.

What has been checked

Every text colour on this site has been calculated. The weakest is 7.0:1, where 4.5:1 is required.
Every page carries its language, Arabic runs right to left. There is a skip link to the content, real landmarks and a visible focus ring.
The site runs no script at all and sets no cookies. It works fully without JavaScript.
If you have asked your system for less motion, you get none here or in the app.
In the app every button has a name for the screen reader, every tap target is at least 48 points, and the interface holds up at 200 percent text size.
The swipe deck can be operated entirely by buttons. A swipe is never the only way.
Charts are put into words for the screen reader instead of standing there as an empty area.
Colour never stands alone: every colour comes with a symbol or a word.
Every recipe image carries a description, and where there is no image the app says so.
Technical abbreviations never stand alone: ALA and EPA/DHA are labelled "omega-3" with one sentence on the difference.
The week start says before each card what the three directions mean, and after each decision which dish went where. Three buttons do the same as the gesture, a fourth takes the last card back.
A notice at startup cannot be tapped away, and that is deliberate. Every way out of it is a button with text, no gesture and no timeout.
In the recipe the time per step is text: the minute it starts, the hands-on time and the unattended time. No bar that says nothing without eyes.
Every core temperature comes with signs you can read without a thermometer. Doneness does not depend on a device.
Every statement on nutrition and health names the body that published it, and the link says beforehand that it opens the browser.

What is still missing

I cannot offer a video in sign language.
The description of each recipe image is derived from the instruction the image was generated from, not verified against the finished picture.
I checked this myself, with tools and tests in the source. A review by disabled users is still outstanding.
The app is translated into eight languages, but the screen reader speaks them only as well as the operating system can.
The week start and the recipe deck use the same swipe gesture with different meanings. The screens are separate, differently coloured and labelled, but a mix-up remains possible.

If something does not work

Write to melden@kernbite.de and describe what you were trying to do and where it failed. Naming your assistive technology and device helps. I reply within seven days and tell you whether and when I will fix it.
