Content Guard - Copy Protection & Advertisement Popup

Protect your WordPress content and show a customizable ad popup when copy or right-click is attempted.

Description

Content Guard prevents content theft and turns every violation into a revenue opportunity — showing your advertisement popup the moment someone tries to copy, right-click, or inspect your content.

Protection features:

• Disable right-click context menu (links remain functional)
• Block copy (Ctrl+C) and cut (Ctrl+X) keyboard shortcuts
• Disable text selection on page (CSS + JS, form inputs excluded)
• Block image and text drag & drop
• Block DevTools keyboard shortcuts (F12, Ctrl+Shift+I/J/C, Ctrl+U)
• Block print shortcut (Ctrl+P)
• Optional: skip protection for logged-in users

Advertisement popup — 5 types:

1. HTML / Rich Text — full WordPress editor, any content
2. Banner Image — upload image + optional click-through link
3. Google AdSense — paste your ad unit code directly
4. Subscribe Form — email input with AJAX submission and optional redirect
5. Video Ad — upload MP4 or embed YouTube / Vimeo

Popup settings:

• Enable/disable popup independently of protection
• Configurable delay (0 = instant)
• Custom overlay color and opacity
• Close on overlay click option
• Accessibility-compliant (ARIA roles, Escape key, focus management)

Selective protection:

• Apply to entire site or selected areas only
• Filter by post type, specific page/post IDs, or categories
• Exclusion list — exempt specific pages even when site-wide mode is on

Shortcode:

Use [cogu_lock] for inline selective protection anywhere in your content. Supports a login gate to hide content from non-logged-in visitors server-side.

[cogu_lock]Your protected content.[/cogu_lock] [cogu_lock require_login="1" message="Please log in."]Content.[/cogu_lock]

Technical highlights:

• Zero jQuery dependency — pure vanilla JS
• OOP architecture with PSR-style autoloading
• No external HTTP requests or CDN calls
• Full i18n / translation ready
• Multisite compatible (uninstall cleans all sites)
• GPL-2.0+ licensed

Installation

1. Upload the content-guard folder to /wp-content/plugins/.
2. Activate the plugin in Plugins → Installed Plugins.
3. Configure at Settings → Content Guard.

Frequently Asked Questions

Does this prevent all content theft?

No JavaScript-based protection is 100% foolproof. Determined users can always view source via the browser's address bar or use screenshot tools. This plugin blocks the most common casual copying methods and deters the majority of users.

Does it affect SEO?

No. Search engine crawlers are not affected because they do not execute JavaScript. Your content remains fully indexable.

Does it work with page builders (Elementor, Divi, etc.)?

Yes. The plugin adds a script and CSS to the frontend — it has no dependency on specific page builders.

Can I protect only specific pages?

Yes. Use the Scope tab to target specific post types, page IDs, or categories. You can also use the [cogu_lock] shortcode for inline control.

Where does subscribe form data go?

The plugin sends an email notification to the address you configure. No data is stored in the database. You can use the cogu_subscribe_submitted action hook to integrate with your own CRM or email service.

Is this plugin multisite compatible?

Yes. Uninstalling removes settings from all sites in the network.
