Privacy Policy

Introduction

Decklist.gg ("we", "us", or "our") is a utility provided by Spellbinder LLC. We respect your privacy and are committed to protecting your personal data. This privacy policy explains how we collect, use, and safeguard your information when you visit our website.

Information we collect

Automatically collected information

When you visit Decklist.gg, we automatically collect certain information about your device and usage patterns through analytics services:

• Usage Data: Pages visited, time spent on pages, click interactions, and navigation paths
• Device Information: Browser type, operating system, screen resolution, and device type (desktop, mobile, tablet)
• Location Data: Approximate geographic location (city/country level) derived from your IP address
• Performance Metrics: Page load times and technical performance data

Information you provide

When you use Decklist.gg to generate deck registration sheets, you may optionally provide:

• Player name (first and last name)
• Event information (tournament name, date, location)
• Deck information (deck name, designer, card lists)

All deck-building and PDF generation happens entirely in your browser using client-side JavaScript. Your deck data never leaves your device and is never transmitted to our servers. The only exception is when you explicitly click "Share Link"—in that case, your deck information is encoded directly into the URL itself (not stored on our servers). Your deck data is saved locally in your browser's localStorage for your convenience, and you can clear it anytime through your browser settings.

How we use your information

We use the automatically collected information to:

• Understand how visitors use our website
• Improve website functionality and user experience
• Identify and fix technical issues
• Analyze popular features and formats (e.g., Standard vs Commander)
• Track PDF download metrics to understand user engagement

Analytics services

Google Analytics

We use Google Analytics to collect and analyze website usage data. Google Analytics uses cookies and similar technologies to track your interactions with our site.

Google may use this data for its own purposes, including improving its services and providing analytics to other websites. For more information about how Google processes your data, visit: Google Privacy Policy

You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on.

Vercel Analytics

We use Vercel Analytics for privacy-friendly website performance and visitor analytics. Vercel Analytics runs automatically without requiring consent, as it does not use cookies and only collects anonymized, aggregated data without personal information. Learn more at Vercel Analytics Privacy.

Cookies and tracking technologies

We use cookies and similar tracking technologies to collect and track information about your usage of the website. Cookies are small data files stored on your device.

Managing your cookie preferences

When you first visit Decklist.gg, you'll see a cookie consent banner where you can accept or reject analytics cookies. You can change your cookie preferences at any time by clicking "Cookie settings" in the footer of any page.

We respect the "Do Not Track" (DNT) browser setting. If you have DNT enabled, we will not load analytics cookies regardless of your consent choice.

Types of cookies we use

• Essential cookies: Required for the website to function properly. These remember your cookie consent preference and theme choice (light/dark mode). These cookies cannot be disabled.
• Analytics cookies: Help us understand how visitors interact with our website (Google Analytics). These cookies require your consent and can be disabled through our cookie settings.

You can control cookies through your browser settings or through our cookie settings dialog. However, disabling essential cookies may affect the functionality of the website.

Third-party services

We use the following third-party services that may collect information:

• Supabase: Provides our card database for validation. See Supabase Privacy Policy.
• Vercel: Hosts our website and provides analytics. See Vercel Privacy Policy.
• Scryfall: We reference card data from Scryfall. See Scryfall Privacy Policy.

Data retention

We retain different types of data for varying periods:

• Deck and registration data: Stored locally in your browser's localStorage. This data persists until you clear your browser data or use a different device. We never store this data on our servers.
• Shareable link data: When you create a shareable link, your deck information is encoded in the URL itself and persists indefinitely as part of the link. This data is not stored on our servers—it's embedded in the URL you share.
• Analytics data: Anonymized usage data collected by Google Analytics is retained according to Google's data retention policies (typically 14-26 months, configurable). Vercel Analytics data is retained according to Vercel's policies.
• Cookie consent preferences: Stored in your browser's localStorage and persists until you clear your browser data.

Since we don't maintain user accounts, we cannot delete "your data" from our servers—because we don't store personal deck data on our servers in the first place. You have full control over your local data through your browser settings.

Data security

We implement industry-standard security measures to protect your information:

• HTTPS encryption: All connections to Decklist.gg are encrypted using HTTPS (TLS/SSL), ensuring that data transmitted between your browser and our servers is secure from eavesdropping or tampering.
• Secure hosting: Our website is hosted on Vercel's infrastructure, which follows industry best practices for security and reliability.
• Client-side processing: By processing your deck data entirely in your browser, we minimize the attack surface and reduce the risk of data breaches.
• No sensitive data storage: We don't store passwords, payment information, or other highly sensitive personal data.

However, no method of transmission over the internet or electronic storage is 100% secure. While we strive to use commercially acceptable means to protect your information, we cannot guarantee absolute security.

Your rights

Depending on your location, you may have the following rights:

• Access: Request a copy of the data we hold about you
• Correction: Request correction of inaccurate data
• Deletion: Request deletion of your data
• Opt-out: Opt out of analytics tracking
• Data portability: Request your data in a portable format

To exercise these rights, please contact us using the information below.

Decklist.gg is not intended for use by children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe we have collected information from a child under 13, please contact us immediately at contact@spellbinder.gg.

We will take appropriate steps to remove the information as soon as possible.

International data transfers

Your information may be transferred to and processed in countries other than your country of residence. These countries may have data protection laws different from your country. By using Decklist.gg, you consent to the transfer of your information to these countries.

Changes to this privacy policy

We may update this privacy policy from time to time. We will notify you of any changes by posting the new privacy policy on this page and updating the "Last updated" date.

Do Not Sell My Personal Information: Decklist.gg does not sell personal information to third parties. We only share data with service providers (like Vercel and Google Analytics) who help us operate the website, and this sharing is not considered a "sale" under CCPA.
