Pie Calendar is developed & tested with accessibility as a primary goal.
We periodically test Pie Calendar's front-end interface with keyboard navigation and a screen reader to ensure that there are no major issues preventing users with specific needs from accessing the content output by our plugin.
Because certain aspects of the front-end output of the plugin, such as colors, are impacted by your theme, we cannot provide a guarantee of compliance with a specific accessibility standard.
That being said, we do take accessibility seriously and meeting or exceeding WCAG 2.1 AA standards is our goal.
If you find any issues regarding accessibility in Pie Calendar, please report them to us at email@example.com and we will be glad to address them.
