Cookie and Data Usage Documentation
At AB Split Test, privacy and transparency are core to how we handle data. Our goal is to provide simple but powerful A/B testing for WordPress without intrusive tracking or unnecessary data collection.
Below is an overview of the cookies used by the plugin, what they do, and how long they are stored.
Overview
AB Split Test is designed to be privacy-first and fully compatible with popular WordPress consent management tools, including Borlabs Cookie, Complianz, CookieYes, and others.
The plugin sets only essential functional cookies required to ensure A/B tests run correctly and that visitors consistently see the same variation during their session.
When Cookie Consent Mode is enabled, no cookies are set until the visitor grants consent through your chosen cookie banner integration.
