2. Information We Collect

This data is collected in aggregated, anonymised form. We do not use this data to identify individual users.

2.3 Local Storage & Session Storage

The Site may save lightweight preferences (such as your chosen colour theme: dark or light) to your browser's localStorage. This data is stored entirely on your device and is never transmitted to us. You can clear it at any time via your browser settings.

4. Third-Party Services

4.1 Google Analytics

We use Google Analytics (property ID: G-4SQS6ZLMB3) to understand how visitors use the Site. Google Analytics collects usage data and processes it in accordance with Google's Privacy Policy. We have enabled IP anonymisation. We do not share any personally identifiable data with Google.

4.2 Google Tag Manager

We use Google Tag Manager (container ID: GTM-KBB4RLGW) to manage the deployment of analytics scripts. Google Tag Manager itself does not collect personal data; it only facilitates the loading of other tags. See Google's Privacy Policy for details.

4.3 Content Delivery

The Site is hosted on Cloudflare Workers / Pages infrastructure. Cloudflare may log standard server access logs (IP addresses, request paths, timestamps) for security and performance purposes. These logs are handled in accordance with Cloudflare's Privacy Policy.

5. How We Use Your Information

The limited analytics data we collect is used exclusively to:

• Understand which features are most useful to our visitors
• Identify and fix technical issues
• Improve the overall performance and usability of the Site
• Measure the reach of the Site (page views, unique visitors)

We do not sell, rent, or share any data with third parties for marketing or advertising purposes.

6. Legal Basis for Processing (GDPR)

If you are located in the European Economic Area (EEA), our legal basis for collecting and using the information described above is our legitimate interests (Article 6(1)(f) GDPR) in understanding how our free tool is used and improving it. We process the minimum data necessary for this purpose.

Where cookies are placed that are not strictly necessary for the operation of the Site, we rely on your consent (Article 6(1)(a) GDPR). You may withdraw consent at any time by adjusting your browser's cookie settings or using the Google Analytics opt-out tool linked above.
