Privacy Policy

🌐 Who We Are

Delvox.xyz is a free educational platform offering academic calculators designed to help students with their studies. We serve users globally — from high school learners to university students — and we take your privacy seriously regardless of where you are located.

📋 What Information We Collect

We do not ask you to create an account or submit personal details to use our calculators. However, some data is collected automatically when you visit our site.

Cookies

When you browse Delvox.xyz, your browser stores small text files called cookies on your device. We use cookies to remember your preferences between visits, understand how visitors navigate our site, and support the delivery of relevant advertisements as described below.

You can control or disable cookies through your browser settings at any time. Note that disabling cookies may affect how some features of the site function.

Log Data

Like most websites, our servers automatically record certain information whenever you visit — commonly called log data. This may include:

• Your device's Internet Protocol (IP) address
• Browser type and version
• The pages you visit on our site and time spent on each
• The date and time of your visit
• The referring URL (the page you came from before reaching our site)

This data is used solely for diagnosing technical issues and understanding general traffic patterns. It is not linked to any personally identifiable information.

Google Search Console

We use Google Search Console to monitor how our website performs in Google Search. This tool provides aggregated, anonymized data — such as which search terms brought users to our site and how pages rank in search results. Google Search Console does not collect personally identifiable information about individual users.

📢 Google AdSense and Advertising

Delvox.xyz displays advertisements through Google AdSense to support the cost of keeping this educational resource free for students. To deliver relevant ads, Google uses cookies — including the DoubleClick cookie — to serve advertisements based on your prior visits to this website and other websites across the internet.

• You may opt out of personalized advertising by visiting Google's Ads Settings.
• You may also opt out of a third-party vendor's use of cookies for interest-based advertising by visiting www.aboutads.info.

We do not share any personally identifiable information with Google AdSense. Google's own privacy practices are governed by their policy at policies.google.com/privacy.

✅ Cookie Consent

Where required by law — particularly for visitors from the European Economic Area — we make commercially reasonable efforts to obtain your consent before placing non-essential cookies on your device. If you continue using our site without adjusting your cookie settings, and where permitted by applicable law, we treat this as acceptance of cookies as described in this policy.

You may withdraw consent at any time by clearing cookies in your browser or adjusting your browser's cookie settings.

⚙️ How We Use Collected Information

We use the data described above solely to:

1. Improve our educational tools — Understanding which calculators students use most helps us build better, more accurate resources.
2. Maintain site performance — Log data and Search Console data help us identify technical issues and improve content quality.
3. Serve advertisements — Ad revenue keeps Delvox.xyz free to access for every student worldwide.
4. Ensure site security — Aggregated traffic data helps us detect and prevent misuse of the site.

We do not sell your data. We do not share it with third parties beyond the service providers listed in this policy — specifically Google Analytics, Google Search Console, and Google AdSense.

🎓 Educational Content and Student Privacy

Delvox.xyz is built for educational use and is open to students of all ages. We take the following steps in line with that mission:

• We do not collect names, email addresses, or any directly identifying personal information through our calculators or any site feature.
• Our tools process all calculations client-side — no calculation inputs are stored on our servers or transmitted back to us.
• We do not use academic performance data or subject-based browsing to target advertising.
• If you are under 18, we encourage you to review this policy with a parent or guardian before using our site.

🛡️ Your Rights as a User

Depending on where you live, you may have specific rights over your personal data.

European Economic Area (GDPR)

You have the right to access, correct, or request deletion of personal data held about you. You also have the right to restrict or object to processing, and to data portability. Because the majority of data we reference is held by Google rather than by us directly, many requests will involve using Google's own account and privacy controls. We will assist where we can.

California Residents (CCPA)

California residents have the right to know what personal information is collected, to request its deletion, and to opt out of the sale of personal information. Delvox.xyz does not sell personal information.

All Other Users

Regardless of your location, you can manage or opt out of cookie-based tracking at any time through your browser settings or Google's opt-out tools linked above. To exercise any privacy rights directly with us, use the contact details at the bottom of this page.

🔗 Third-Party Links

Our site may occasionally link to external educational resources or references. Once you leave Delvox.xyz, this privacy policy no longer applies. We encourage you to review the privacy policy of any third-party site you visit.

🗂️ Data Retention

Because we do not directly collect or store personally identifiable user data, we do not maintain individual user records. Cookie and analytics data is managed according to the retention policies of each respective third-party service. You can clear cookies stored in connection with our site at any time through your browser settings.

This Privacy Policy is linked in the footer of every page on Delvox.xyz so it is always easy to find.

🔄 Changes to This Policy

We may update this Privacy Policy from time to time as our site grows or as legal requirements change. When we do, we will update the date at the top of this page. We encourage you to check back periodically, especially if you use Delvox.xyz regularly.
