Power-ups
Server-side extensions that neither the browser nor an ad-blocker can see. You enable them in the dashboard with one click.

Anonymizer
30+ rules for PII. GDPR-ready.
Bot Detection
Filters automated traffic. In our deployments, +15–20% data quality.

Stripe Events Forwarder
Server-side propagation of Stripe webhooks (purchase, refund, subscription) as conversion events into GA4, Meta CAPI, Google Ads — no GTM tags needed, no templates to write.
- ✓ Stripe-Signature verification (HMAC-SHA256)
- ✓ Auto event_id from payment_intent → deduplication with the Pixel event
- ✓ Recurring revenue: invoice.paid for subscriptions
- ✓ We forward refunds back as a reverse conversion
