Suziwan

Suziwan Referrer Log is a simple yet powerful analytics tool developed in Nice, France, with privacy in mind. Unlike heavy third-party services, this plugin stores visitor source data locally on your server, giving you full ownership of your data.
It is specifically designed to track: 
* External Referrers: See which websites are sending traffic to your site. 
* Full UTM Tracking: Log source, medium, campaign, term, and content for your marketing campaigns. 
* Visitor Metadata: Capture landing URLs, browser languages, and user agents. 
* Data Management: Includes a settings page to easily clear all logs or purge old data (e.g., keep only the last 30 days) to keep your database lean.
Privacy First: 
To comply with global privacy standards like GDPR, this plugin automatically anonymizes IP addresses by masking the last octet before saving them to the database. No personally identifiable information (PII) is stored.

Suziwan Referrer Log

A lightweight, privacy-friendly way to log referrers, UTM parameters, and visitor metadata directly in your WordPress database.

This plugin displays a greeting message to visitors that come from different urls (known as referrers). For example, you may want to welcome Diggers with a message that reminds them to digg your story, or you may want to ask Del.icio.us users to bookmark your post, and so on.
Not only about a cool greeting box, it greatly helps to more efficiently interacts with your readers and build a better relationship between you (your website) and them.
