Guardian Digital Studios ("we", "us", or "our") operates Commander Index, accessible at commander-index.com. This Privacy Policy explains how we collect, use, and protect your information when you use our service. By using Commander Index, you agree to the practices described here.

Questions or concerns can be directed through our website at guardiandigitalstudios.com.

We collect information you provide directly when using the service:

• Account data — email address, username, and password (stored securely via Supabase Auth)
• Profile data — optional display information such as avatar, favorite cards, guild color theme, and tagline
• Deck and match data — deck lists, power scores, match results, and pod membership information you submit
• Community content — feature suggestions, challenge submissions, comments, and other content you post

We do not collect payment information. Commander Index is a free service.

We use the information we collect to:

• Provide and operate the Commander Index service
• Display your profile, decks, and match history to you and your pod members
• Generate leaderboards, win rate statistics, and community rankings
• Improve and develop new features based on community usage
• Respond to support requests or account issues

We do not sell your personal information to third parties.

Your data is stored using Supabase, a cloud database platform. Data is hosted on Supabase's infrastructure. By using Commander Index, you acknowledge that your data will be processed and stored by Supabase in accordance with their terms and privacy policy.

Commander Index integrates with the following third-party services:

• Scryfall API — used to look up Magic: The Gathering card data (card names, images, types, and prices). Scryfall receives card search queries but does not receive your account information.
• Google AdSense — used to display advertisements. Google may collect usage data and set cookies in accordance with their own privacy policies. You can learn more at policies.google.com/privacy.

You can request deletion of your account and associated data at any time through the Settings page. If you encounter any issues, you can contact us through guardiandigitalstudios.com.

Deck data you have marked as public may be visible to other users. Making a deck private or deleting it removes it from public view.

Commander Index is not directed at children under 13 years of age. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided us with personal information, please contact us so we can remove it.

We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. Continued use of Commander Index after changes constitutes acceptance of the updated policy.
