Core capabilities
A complete anti-fraud stack — bundled into one plugin.
Behavioral biometrics, order-graph linking, and a closed-loop chargeback model — flat-fee, self-hosted, no per-transaction cut.
Order-graph linking
Cluster orders by shared device, normalized email, fuzzy address, phone, BIN+last4. Surface fraud rings before the second order completes.
Chargeback feedback loop
Stripe and PayPal webhooks ingest disputes. Auto-blacklist linked atoms. Recompute scores on pending orders sharing graph edges.
Explainable scoring
Each rule's contribution is shown on the order. Paste it straight into a chargeback rebuttal — optionally translated to plain English by OpenAI.
Configurable playbook
Per-threshold actions: auto-cancel, hold-on-review, email admin, custom denial message at checkout. Per-rule weights you control.
Privacy-first design
MaxMind / OpenAI optional. EU-only-vendors mode disables external services. GDPR erasure hook supported.
Workflow
Every order travels through the same four stages.
Drop the plugin in, weight your rules, let it score — and watch each chargeback sharpen the next decision.
Install & activate
Standard WooCommerce plugin install. Auto-detects HPOS, Cart/Checkout Blocks, and your active payment gateways.
Tune the playbook
Set thresholds for approve / review / hold / cancel. Weight each rule. Optionally enable behavioral biometrics on checkout.
Score & act
Every order receives an explainable score. Linked-orders panel surfaces rings instantly. Pending orders re-score when chargebacks fire.
Learn & improve
Stripe + PayPal dispute webhooks feed back into scoring. Tagged outcomes are saved for future model training.

FAQ
Common questions.
Does WooFraudGuard require a third-party service?
No. The built-in checks run entirely on your server. MaxMind minFraud and OpenAI are optional and only activate when you paste in your own API keys.
Is it HPOS-compatible?
Yes. WooFraudGuard declares compatibility with WooCommerce’s High-Performance Order Storage and Cart/Checkout Blocks.
Will it work alongside Stripe, PayPal, and WooPayments?
Yes. The chargeback feedback loop targets Stripe and PayPal in v0.2; additional gateways are on the roadmap. Scoring runs regardless of gateway.
How are the behavioral signals collected?
A small, opt-in JavaScript collector runs on the checkout page. It captures non-identifying signals (paste-vs-type, autofill, time-on-page, mouse entropy) and attaches a signed payload to the order. Off by default — enable it once you’ve reviewed your privacy policy.
What does the license key do?
Your purchase generates a license key that activates auto-updates and unlocks premium rule packs as they ship. You can manage activations from your CHADA Store account.
Do you offer refunds?
30-day no-questions-asked refund. If WooFraudGuard doesn’t reduce fraud on your store, we’ll refund you in full.
