Full GDPR compliance and Google Consent Mode v2 — completely free. No paywalls, no locked features, no upsells ever.

Description

Justbo Consent Banner gives you complete Google Consent Mode v2 support and GDPR compliance for free — no subscriptions, no premium tiers, no feature gates.

Most cookie consent plugins charge $10–$20/month to unlock Google Consent Mode v2. Justbo Consent Banner includes it all at no cost.

Google Consent Mode v2 — Full Implementation

All four required parameters are supported out of the box:

  • ad_storage — advertising cookies
  • analytics_storage — analytics cookies
  • ad_user_data — sending user data to Google
  • ad_personalization — remarketing and personalized ads

Default consent is set to denied before any user interaction — exactly as Google requires.

Direct Integrations — No GTM Required

Enter your IDs in the settings and the plugin handles the rest:

  • Google Analytics 4 (G-XXXXXXXXXX) — injects gtag.js directly
  • Google Ads (AW-XXXXXXXXXX) — conversion tracking snippet
  • Meta / Facebook Pixel — completely blocked until the user grants advertising consent

Modern, Customizable Banner

  • Two layouts: floating card (bottom-right corner) or centered modal
  • Custom primary color, background, text color, and border radius
  • Smooth CSS animations, fully responsive on mobile
  • Custom CSS field for pixel-perfect styling control

Granular Consent Categories

Users can accept all, reject all, or choose individually:

  • Necessary (always active)
  • Analytics
  • Advertising

Consent Logging — GDPR Accountability

Every consent decision is recorded in the WordPress database:

  • SHA-256 hashed IP address (GDPR-safe, no raw IPs stored)
  • Consent scope (which categories were accepted)
  • Consent version
  • Timestamp

View logs in the admin panel and export to CSV with one click.

Consent Versioning

Update your privacy policy? Increment the consent version number (e.g. 1.0 → 1.1) and all returning users will see the banner again automatically.

Statistics Dashboard

  • Acceptance rate, rejection rate, customization breakdown
  • Per-category analytics and advertising consent rates
  • CSS-only bar charts — no JavaScript libraries required
  • Filter by last 7 days, 30 days, or all time
  • Integration status overview with link to Google Tag Assistant

Lightweight & Fast

  • Vanilla JavaScript — zero jQuery dependency
  • ~6 KB JS (gzipped), ~3 KB CSS (gzipped)
  • No external requests for the banner itself
  • Scripts loaded only on the frontend, never in the admin

This Plugin Is Free — Forever

Justbo Consent Banner has no premium plan. Everything described above is included in the free version. If it helps you, consider buying me a coffee ☕.

Frequently Asked Questions

Is this plugin compliant with Google Consent Mode v2?

Yes. It implements all four required parameters: ad_storage, analytics_storage, ad_user_data, and ad_personalization. Default consent is set to denied before any scripts load, and updated immediately after the user makes a choice.

Do I need Google Tag Manager?

No. You can enter your GA4 Measurement ID (G-XXXXXXXXXX) or Google Ads ID (AW-XXXXXXXXXX) directly in the plugin settings. The plugin injects the correct snippets into your page automatically.

Does Meta Pixel fire before consent is given?

No. The pixel script is completely blocked until the user explicitly accepts advertising cookies. It is loaded via a JavaScript wcc:consent event — no data is sent to Facebook before consent is granted.

Are consent records stored?

Yes. Every consent decision is saved to the WordPress database with a SHA-256 hashed IP (no raw IPs), the scope of consent, the consent version number, and a timestamp. You can view and export these records from the admin panel at any time.

What happens when I update my privacy policy?

Go to Settings → Justbo Consent Banner → Google section and increment the Consent Version (e.g. from 1.0 to 1.1). All returning visitors will be shown the consent banner again on their next visit.

Is this plugin really free?

Yes. There are no premium plans, no feature locks, and no upsells. Every feature described here is available in the free version.

Is the plugin GDPR / RODO compliant?

Yes. It was built specifically for EU/EEA compliance: default deny before interaction, consent logging with hashed identifiers, consent versioning for policy updates, and a granular category system (Necessary / Analytics / Advertising).

Can I style the banner to match my website?

Yes. You can change colors, border radius, and button labels in the settings. There is also a Custom CSS field where you can write any additional styles using #wcc-banner as the parent selector.
