Charitable comes with a few settings that you will find in the WordPress Customizer. To change these settings, go to Appearance > Customize, then click on the Charitable tab.
Design Options
Under Design Options, you can set the highlight colour that Charitable will use for buttons, progress bar and other highlights.
Donation Form
Under Donation Form, you can set how you want a campaign’s donation form to show, and whether you want it to only show required fields.
User Privacy and Terms & Conditions
The donation form includes a section that can include your terms and conditions, a note about how personal data is used on your website (including a link to your privacy policy) and a checkbox allowing donors to consent to being contacted in future.
All of these settings, including the text used and the linked pages for terms and conditions and the privacy policy, are managed via the Customizer.
