FrostBanner – Cookie Consent Banner

FrostBanner adds a cookie consent banner to your WordPress site. You design it in the FrostBanner dashboard and it appears on your site without editing your theme.

This plugin connects your site to the FrostBanner service at frostbanner.com. You need a FrostBanner account to use it. A free plan is available. See “External services” below for what is sent and when.

Features

• 14 styles in 6 shapes: corner card, bottom bar, centred window, pill, chat message and card with image
• Light, dark and tinted themes, your own colour
• Blocks scripts until consent: Google Analytics, Meta Pixel and anything else you mark with a category
• Blocks YouTube, Google Maps and other iframes until consent, with an “Allow and show” placeholder
• Google Consent Mode v2 signals
• Equal “Accept all” and “Reject all” buttons, granular categories, a floating button to change the choice at any time
• Consent log with CSV export, in your FrostBanner dashboard
• Built-in texts in 29 languages (all EU languages plus Norwegian, Catalan, Turkish, Ukrainian and Russian), all texts can be replaced
• About 18 KB compressed, no dependencies, does not touch your site’s CSS (Shadow DOM)

The banner script is open source (MIT): https://github.com/automatept-ai-pt/frostbanner

How to set it up

1. Install and activate the plugin.
2. Go to Settings → FrostBanner and click “Connect to FrostBanner”.
3. Sign in with Google, GitHub or your email (a free plan is available). Your site is added and connected automatically, and you come back to WordPress.

The banner appears right away with the default style. Already have a FrostBanner site? You can also paste its site ID by hand in Settings → FrostBanner.

Style, texts, categories and language are changed in the FrostBanner dashboard and published to your site automatically.

Block a script until consent

Change the script type to text/plain and add its category. FrostBanner runs it only after the visitor accepts that category:

<script type="text/plain" data-category="analytics" src="https://www.googletagmanager.com/gtag/js?id=G-XXXXXXX" async></script>

Cookie settings link

Use the shortcode [frostbanner_settings] in your footer or cookie policy page to show a link that reopens the preferences. Change the text with [frostbanner_settings label="Manage cookies"].

External services

This plugin relies on the FrostBanner service, operated by automate-ai.pt (Portugal). Nothing is loaded and no data is sent until you connect the site or save a site ID in Settings → FrostBanner.

• Connecting. Only when an administrator clicks “Connect to FrostBanner”, the browser opens https://app.frostbanner.com/app/ with this site’s domain, the WordPress admin address to return to and a one-time security code. After you sign in and confirm, FrostBanner sends the site ID back to that address.

After a site ID is saved:

• Banner script. Every visitor’s browser loads the banner script from https://app.frostbanner.com/v1/fb.js on each page view. As with any web request, the visitor’s IP address and browser information reach the server.
• Banner settings. The script loads the style and texts you published from https://app.frostbanner.com/v1/config/<your site ID>. Only your site ID is sent. A copy is kept in the visitor’s local storage.
• Consent log. When a visitor accepts, rejects or changes their choice, the script sends to https://app.frostbanner.com/v1/consent: your site ID, a random consent ID, the chosen categories, the banner version and the page address. The service stores the country and a salted hash of the IP address, never the IP address itself.

On the visitor’s device the script stores one first-party cookie and a local storage value named fb_consent with the consent ID, the choices, the banner version and the date.

The free plan shows a small “Powered by FrostBanner” text (not a link) inside the banner. It is added by the service, not by this plugin.
