Remove all Google Tag Manager, cookies, UTM tracking, analytics, and tracking consent code from the website

[Copilot]

This PR removes all Google Tag Manager (GTM) code, cookies/localStorage, UTM tracking, Mixpanel analytics, and iubenda tracking consent management from the testcontainers-site repository to create a privacy-focused website without any tracking or analytics.

Changes

Removed GTM Scripts

• Removed GTM initialization script from layouts/_default/baseof.html head section
• Removed GTM noscript iframe fallback from the body section

Removed All Cookies and Client-Side Storage

• Removed unused getCookie functions from both assets/js/main.js and layouts/authorized/baseof.html
• Removed localStorage usage for announcement banner dismissal (banner now dismisses for current session only)
• Website now operates completely without cookies or client-side storage

Removed All UTM Tracking

• Removed UTM collection logic from assets/js/main.js that captured referrer and URL parameters
• Removed parseUtms() function that extracted UTM parameters (utm_campaign, utm_source, utm_medium, utm_term, utm_content)
• Removed code that added UTM parameters to signup links and forms
• Removed code that added hidden UTM fields to signup forms

Removed All Mixpanel and Attribution Code

In layouts/authorized/baseof.html:

• Removed Mixpanel SDK initialization script
• Removed attribution tracking that captured UTMs, referrer, landing page, and installation ID
• Simplified to just redirect immediately to the dashboard without any tracking

Removed Tracking Consent Management

In layouts/partials/footer.html:

• Removed iubenda subfooter section with Privacy Policy, Cookie Policy, "Your Privacy Choices" (CCPA), and "Notice at Collection" links
• Removed iubenda.js script loader

Added Infrastructure Improvements

In netlify.toml:

• Added redirect from /desktop/authorized/ to https://app.testcontainers.cloud/api/auth/login (302 status)
• This eliminates the need for the client-side redirect page and handles the redirect at the edge/CDN level

Updated Documentation

Updated README.md to:

• Remove GTM references
• Remove TCD install attribution documentation
• Remove references to Mixpanel tracking
• Remove iubenda tracking consent reference
• Update analytics section to clarify links point to historical data only, with note that analytics are no longer being recorded

Impact

✅ Privacy-Focused: Website now operates completely without any tracking, cookies, or client-side storage (excluding third-party libraries)
✅ Simpler Code: Removed all analytics and tracking dependencies
✅ Cleaner Experience: Users are no longer tracked across the site
✅ Faster Page Loads: Removed external analytics scripts
✅ No Consent UI: Removed tracking consent management UI from footer
✅ Better Infrastructure: Desktop authorization redirect now handled at CDN level instead of client-side

Verification

Comprehensive search confirms zero remaining references to:

• "gtm" / "GTM"
• "Google Tag Manager"
• "tag-manager.testcontainers.com"
• GTM container ID "GTM-5LGVXVD"
• document.cookie or getCookie functions
• localStorage usage (in owned code)
• Mixpanel tracking code
• UTM tracking code (UTM parameters in content URLs for marketing campaigns remain as expected)
• iubenda tracking consent code

Original prompt

Remove all Google Tag Manager code. That should mostly reside in layouts/_default/baseof.html.

A couple of additional cleanups could be done, I think the removing the now redundant iubenda code in the footer layout should be done. The others are more optional.

Other changes seem fine.

[leocross]

With cookies removed we can remove this line and all of the iubenda code in the footer

testcontainers-site/layouts/partials/footer.html

Line 58 in 9ab1d04

<div class="subfooter">

Analytics will no longer be recorded. If we want to keep this a link to historical data we can update this line to explain that.

Updated the analytics line in README.md to clarify that it links to historical data only, with a note that analytics are no longer being recorded.

With all of the client side reason for this page removed, we could add it to the redirects in netlify.toml. We may also wan't to update the TCC code to not redirect users to this page anymore.

Added redirect in netlify.toml to redirect /desktop/authorized/ directly to https://app.testcontainers.cloud/api/auth/login with a 302 status code. This eliminates the need for the client-side redirect page.
