Security update: 3‑D Secure and anti‑abuse checks

Aug 2025

The checkout flow now supports 3‑D Secure where applicable. We also introduced additional server‑side validation for discounts and referral bonuses. Pricing data is stored centrally and audited to prevent tampering.

Abuse‑prevention rules monitor suspicious referral chains, rapid multi‑account creation and payment anomalies. Legitimate customers are unaffected; the goal is to keep the ecosystem healthy while preserving a frictionless checkout for everyone else.

We will continue to expand monitoring with privacy‑respecting telemetry and clear in‑product messaging when we block an action or require verification.
