Personalize checkout text

If you look at the WooCommerce docs, you’ll see that you can override template parts by having a replacement file in a woocommerce folder in your theme. A lot of the text you’re talking about is hardcoded into woocommerce > templates > checkout > review-order.php Copy that file and modify as needed. Normally I would advocate for trying to use filters instead of duping the template file but I think there’s going to be a few things you will have to do in that template file to accomplish what you need.
