3. Mandatory Requirements

Essential Consent for Laboratory Access

To use the tools on our home page, users must explicitly grant cookie consent by selecting "Accept All" in the banner. This consent is essential because:

Infrastructure Funding: Our free tools are sustained by Google AdSense, which requires cookies for ad delivery and verification.
Feature Verification: The laboratory main screen verifies the presence of mandatory services before unlocking tool categories.
User Experience: We use local cookies to remember your preferences (like Dark Mode).

Service availability depends on active browser consent markers.

4. Third-Party Cookies

We use third-party cookies from Google for analytics and advertising. Google uses cookies to serve ads based on your prior visits. You may opt out via Google Ad Settings.

5. How to Control Cookies

Most web browsers allow you to control cookies through their settings:

Chrome: Settings → Privacy and security → Cookies and other site data
Firefox: Settings → Privacy & Security → Cookies and Site Data
Safari: Settings → Privacy → Manage Website Data
Edge: Settings → Cookies and site permissions → Cookies and site data

6. Consent Banner Implementation

Our cookie consent banner is implemented with the following logic stored in common.js. It checks localStorage and shows the banner once to first-time visitors.

// Cookie Banner Logic (common.js)
192: var banner = document.getElementById('cookie-banner');
193: var acceptBtn = document.getElementById('accept-cookies');
194: if (localStorage.getItem('tlz-cookies') !== 'accepted') {
195:     setTimeout(function() {
196:         banner.classList.remove('translate-y-full');
197:     }, 1000);
198: }
199: acceptBtn.addEventListener('click', function() {
200:     localStorage.setItem('tlz-cookies', 'accepted');
201:     banner.classList.add('translate-y-full');
202: });
