Privacy Policy

WealthFamePower ("we", "us", "the site") is a fan-made One Piece TCG database. This privacy policy explains what data we collect, how we use it, and your rights regarding that data. We are committed to keeping your information safe and being transparent about our practices.

Data We Collect

Discord Authentication

If you choose to sign in, we use Discord OAuth to authenticate your identity. We receive and store the following from Discord:

• Discord user ID
• Username
• Avatar URL

We do not store your Discord password, email address, or access your Discord messages.

Watchlist and Preferences

When signed in, we store your watchlist cards and price alert targets in our database, associated with your Discord user ID.

Local Storage

We use your browser's localStorage to remember your preferences locally on your device. This includes your language preference (English or Japanese), card grid layout preference (grid or list view), and recently viewed cards (last 20). This data never leaves your browser.

Cookies

If you sign in with Discord, we set a single HTTP-only session cookie to maintain your login session. This cookie contains a session identifier (not your personal data) and expires after 30 days. No tracking cookies are set. No third-party advertising cookies are used.

Third-Party Services

We use the following third-party services:

• Vercel -- Hosts our frontend. Vercel Analytics collects anonymous page view data (no personal identifiers). Vercel Speed Insights collects anonymous Core Web Vitals performance metrics.
• Cloudflare -- Provides our backend tunnel and analytics beacon. Cloudflare Web Analytics collects anonymous visitor metrics without using cookies or tracking individuals.
• Discord -- Used for authentication. When you sign in, Discord's own privacy policy governs the data they collect during the OAuth flow.
• TCGCSV / TCGPlayer -- We fetch card pricing data from TCGCSV (a public cache of TCGPlayer data). No user data is sent to these services.

Data Retention

Login sessions expire after 30 days. Watchlist data is retained as long as your account exists. We do not sell, share, or transfer your personal data to any third party for marketing or advertising purposes.

Your Rights

You can remove cards from your watchlist at any time. You can clear your browser's localStorage to remove locally stored preferences. If you would like your account data deleted entirely, please contact us via our Discord server.

Changes to This Policy

We may update this privacy policy from time to time. Any changes will be reflected on this page with an updated date.
