Working Copy Pro is distributed under the GPL v2 (or later) license, like WordPress itself. Your purchase buys a license key that enables automatic updates, Pro feature activation, and support for the number of sites in your plan, for one year from purchase.
14 days from purchase, no questions asked. Email support@workingcopywp.com from your order email.
Licenses renew annually. Cancel anytime before renewal; already-activated sites keep their Pro features, but stop receiving updates and support.
License activation records your site URL, WordPress version, and plugin version, used solely to enforce seat counts and deliver updates. No content from your site is ever transmitted.
