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.

Simple Web Marketing

The Simple Web Marketing Attribution plugin captures attribution data from users visiting your site, including UTM parameters, referrer information, and automatic detection of webmail providers (Gmail, Yahoo, etc.) and search engines. It stores this data in the visitor’s browser local storage and automatically submits it to hidden fields in forms. Capturing these attribution utm parameters with your lead records will let you run reports on your customer database to see which marketing channels result in customers and which do not.
The plugin also includes a link builder tool to help you generate UTM tags for your marketing campaigns and a link library to keep track of the UTM tags you have generated.
The plugin is tested and works with:
<ul>
<li>HubSpot</li>
<li>Salesforce (Web-to-Lead)</li>
<li>Contact Form 7</li>
<li>WPForms</li>
<li>Ninja Forms</li>

<h3>External services</h3>
This plugin optionally connects to two external services, both operated by Simple Web Marketing. Connection to the Simple Web Marketing Cloud is opt-in and can be disabled from the Settings screen at any time.
Simple Web Marketing Cloud (opt-in)
<ul>
<li>Service: Simple Web Marketing Cloud Platform (operated by Simple Web Marketing, simplewebmarketing.com)</li>
<li>Purpose (registration): When cloud sync is first enabled, the plugin registers your site by sending your site URL, admin email address, and site name to the registration endpoint. This creates an account and returns an API key that is stored locally. Registration only happens once per site.</li>
<li>Purpose (conversion sync): After each form submission or phone-click conversion recorded locally, the plugin sends the UTM attribution data (source, medium, campaign, term, content), page URL, event type, and timestamp to the SWM Cloud ingest endpoint. This is a fire-and-forget request that does not affect page performance.</li>
<li>Data Sent: Site URL, admin email (registration only), site name (registration only), UTM parameters, page URL, event type, timestamp.</li>
<li>When data is sent: Only when cloud sync is enabled in Settings and only on conversion events.</li>
<li>Terms & Privacy: <a href="https://www.simplewebmarketing.com/terms/" rel="nofollow ugc">Terms of Service</a> — <a href="https://www.simplewebmarketing.com/privacy-policy/" rel="nofollow ugc">Privacy Policy</a></li>
</ul>
HubSpot Forms API (opt-in, existing feature)
<ul>
<li>Service: HubSpot Forms API (provided by HubSpot, Inc.)</li>
<li>Purpose: To submit form data and associated marketing attribution metadata (UTM parameters, referrer) from your site to your HubSpot portal when the HubSpot Proxy feature is used.</li>
<li>Data Sent: When a visitor submits a form configured with our tracking, the plugin sends the form field values (user-provided input), the page URL, the page title, and captured attribution data (UTM source, medium, campaign, term, content, and full attribution log).</li>
<li>Terms & Privacy: This service is subject to HubSpot’s <a href="https://legal.hubspot.com/terms-of-service" rel="nofollow ugc">Terms of Service</a> and <a href="https://legal.hubspot.com/privacy-policy" rel="nofollow ugc">Privacy Policy</a>.</li>
</ul>
