Pseudonymous Billing
RAILGUN uses a privacy-preserving billing system. When you subscribe, Stripe only sees a one-way cryptographic hash — never your username, email, or identity. Your subscription status is verified offline using an Ed25519-signed token stored locally on your device. We can't link your payment to your account even if compelled.
