Geo-Detection

The Geo-Detection tab lets you show the consent dialog only to visitors from regions that require it, while allowing others through automatically.

Geo-Detection tab with Browser Language Detection, Consent Required Regions and the action for non-EU visitors

Browser Language Detection

Setting Details
Field Browser Language Detection
Type Toggle (Yes/No)
Default No (disabled)

When enabled, the plugin reads the visitor's Accept-Language HTTP header to infer their region. Visitors from consent-required regions see the dialog; others are handled according to the non-EU action setting.

Setting Details
Field Consent Required Regions
Type Checkboxes
Default All checked (EU, EEA, UK)
Visible when Browser Language Detection is Yes

Select which regions require the consent dialog:

Region Languages Detected Countries
EU Countries de, fr, it, es, pt, nl, pl, cs, sk, hu, ro, bg, hr, sl, lt, lv, et, fi, sv, da, el, ga, mt The main languages of the 27 EU member states
EEA (Norway, Iceland) no, nb, nn, is (Norwegian Bokmål and Nynorsk included) Norway, Iceland
UK & Ireland en-gb, en-ie United Kingdom, Ireland

Action for Non-EU Visitors

Setting Details
Field Action for Non-EU Visitors
Type Dropdown
Default Auto-agree (load maps immediately)
Visible when Browser Language Detection is Yes
Option Behavior
Auto-agree (load maps immediately) Silently sets the consent cookie to agree and shows maps immediately. The visitor never sees the consent dialog. (default)
Show consent box (let visitor decide) Shows the consent dialog to these visitors as well. Useful if you want to offer the choice everywhere.
Skip plugin entirely The plugin does nothing for non-EU visitors — no consent cookie, no stripping, no dialog. Use this only if another mechanism handles map consent for non-EU traffic.

How It Works

  1. When a visitor loads a page, the plugin checks the Accept-Language header
  2. The header contains language tags like en-US,en;q=0.9,de;q=0.8
  3. The plugin checks each tag against the configured consent regions
  4. If any tag matches a consent region, the visitor sees the consent dialog
  5. If no tags match, the non-EU action is applied

Important Notes

  • Safe default: If no Accept-Language header is present (e.g., bots, API clients), the consent dialog is shown as a precaution
  • English is special: The bare language code en does not trigger consent — only en-gb and en-ie do. This prevents showing the dialog to en-us visitors when only the UK region is selected
  • Not IP-based: This detection uses browser language preferences, not IP geolocation. A German user traveling in the US will still see the consent dialog because their browser language is de
  • No external API calls: The detection is entirely server-side using the HTTP header — no third-party geolocation services are contacted

Limitations

Browser language detection is an approximation. It reflects the visitor's language settings, not their physical location. For most sites this is a reasonable trade-off that avoids the privacy concerns and costs of IP-based geolocation. Some EU languages, such as Catalan, Basque, Galician and Luxembourgish, are not in the list, so those visitors count as outside the EU. When in doubt, disable geo-detection to show the consent dialog to all visitors.
