Privacy Policy

Last updated: May 19, 2026

Overview

Elder Dragon Tutor ("the App") is a free, open-source tool for generating Magic: The Gathering Commander/EDH decklists. We are committed to protecting your privacy. This policy explains what data we collect (spoiler: almost none).

Data We Collect

We do not collect any personal data.

The App does not require account creation, login, or any form of registration. We do not collect, store, or transmit:

• Names, email addresses, or contact information
• Location data
• Device identifiers
• Usage analytics or tracking data
• Cookies or local storage for tracking purposes

Third-Party Services

The App communicates with the following third-party APIs to function:

• Scryfall (scryfall.com) — Card data, images, and pricing. Subject to Scryfall's terms.
• EDHREC (edhrec.com) — Commander recommendations and average deck data.
• Commander Spellbook (commanderspellbook.com) — Combo data.

These services may log standard HTTP request data (IP address, user agent) on their end according to their own privacy policies. We have no control over or access to that data.

Local Storage

The App may use your browser's local storage or service worker cache to store previously fetched card data for performance purposes. This data stays on your device and is never transmitted to us or any third party.

Children's Privacy

The App does not knowingly collect any information from children under 13. Since we collect no personal data from anyone, this applies universally.

Changes to This Policy

We may update this privacy policy from time to time. Changes will be posted on this page with an updated date.
