Pricing Proof

Yes. Proof is a free, open-source plugin licensed under GPLv2 or later. The full core feature, sales notifications built from real orders, is available at no cost. The paid Proof Pro add-on adds product-review popups.

Yes. Proof is a WooCommerce extension and declares WooCommerce as a required plugin, so it will not activate without it. It needs WooCommerce 8.0 or later, WordPress 6.5 or later, and PHP 8.1. Notifications are built from your WooCommerce orders.

Only the buyer's billing first name and city. Surnames, emails, full addresses and order numbers never leave the server. When an order has no first name, Proof substitutes a word you choose (the default is "Someone").

No. Every popup comes from a real WooCommerce order with the status completed or processing. Proof never invents counters or demo data. When there are no qualifying orders, no script or widget is loaded at all.

Up to the 40 most recent orders with the status completed or processing from roughly the last 30 days. From each order only the first product name plus the buyer's first name and city are taken. The query runs at most once every five minutes and the result is stored in a transient.

No. The script is a small, dependency-free piece of vanilla JS loaded with defer in the footer. Order data is cached in a transient, so the store does not re-query on every page view. The popup is fixed to a corner, so it never moves other content or adds to Cumulative Layout Shift.

Yes. Every plugin, free and PRO, is licensed under the GPL. You are free to use, modify and self-host the code on your own sites, and a PRO purchase does not restrict those GPL freedoms. A PRO licence adds automatic updates and product support, not different rights to the code.

Yes. The free edition is a complete product on WordPress.org, not a time-limited trial, so you can run it indefinitely. It covers the core use case in full, and you upgrade to PRO only when your store needs the advanced features. There is no account or card required to use the free edition.

Each plan covers a set number of sites: a single site, five sites, or unlimited sites. The licence is tied to your account and determines how many sites receive automatic updates and support. If your store grows beyond your plan, you can upgrade to a larger site count at any time.

Yes. PRO purchases include a 30-day money-back guarantee unless a product page states otherwise. If the plugin is not the right fit, request a refund within 30 days through Freemius support or [email protected]. Refunds are returned to your original payment method.

Checkout is handled by Freemius, our Merchant of Record. Freemius processes the payment, applies the correct VAT for your country, issues the invoice, and manages renewals. If you have a valid EU VAT ID, you can enter it at checkout to apply the reverse-charge exemption.

PRO licences are annual and renew automatically while auto-renewal is enabled, so your updates and support continue without interruption. You can cancel future renewals at any time from your Freemius account before the renewal date. Cancelling stops future charges while your current term stays active until it ends.

An active PRO licence includes email support for installation, configuration and defects in our own plugins, on a best-effort basis with no guaranteed response time. Support does not cover custom development, theme customisation, or conflicts caused by third-party plugins. For the free edition, community help is available through WordPress.org and GitHub.

Yes. We recommend installing and fully testing any plugin on a local copy or a staging environment identical to production, with a current backup, before activating it on a live store. This lets you confirm compatibility with your theme and other plugins without risking your production site. Installing directly on production is at your own risk.
