Privacy Policy

ProspectWatch Privacy Policy

ProspectWatch keeps personal data collection narrow for the MVP and avoids payment, shipping, trade, and ownership-verification workflows.

Information We Collect

We may store your email address, authentication session metadata, watch entries, card tracking details, app preferences, and operational logs needed to run and protect the service.

Information We Avoid

ProspectWatch does not process payments, run trades, store shipping details, verify card ownership, or intentionally collect government IDs or financial account information.

How We Use Information

We use information to create and secure accounts, save watch entries, show player/card monitoring data, improve reliability, investigate abuse, and operate production checks.

Service Providers

ProspectWatch may use service providers such as Supabase for authentication/database storage, Cloudflare for hosting, and GitHub Actions for scheduled jobs and operational workflows.

Sharing

We do not sell your personal information. We do not publish your private watchlist unless a future opt-in public profile feature is added and you choose to enable it.

Retention and Deletion

We keep account and watchlist data while your account is active or as needed for service operation, security, troubleshooting, or legal compliance. For privacy or deletion requests, contact support [at] prospectwatch.app from the account email when possible.

Security

We use access controls, row-level security, and privileged credential separation where supported. No internet service can guarantee perfect security.

Children

ProspectWatch is not directed to children under 13, and users must be 13 years old or older.

Jurisdiction Note
