Pay for the events you track, not the seats you add.

Meta, Google, and GA4 each claim conversions with their own pixel and attribution window, so the numbers never agree. Signal Sparrow attributes paid spend to your real Stripe MRR and reconciles every view to the cent — one number you can trust, not three that conflict.

About 30 minutes. You add a lightweight tracking snippet to your site and connect Stripe and your ad accounts over OAuth. No data team, no implementation project, no sales call required.

Yes. We forward paying-customer conversions server-side to Meta CAPI, Google Ads, and GA4, keyed on hashed first-party identity — so the platforms optimize toward revenue, not just pixel fires. PII is hashed before it ever leaves your workspace.

An event is a tracked interaction ingested in a billing period, metered on server-receive time. The Free plan pauses ingestion at its cap; paid plans keep processing and bill overage in 50,000-event blocks. We notify you at 80% and 100% of your allowance and recommend the next tier.

Data is encrypted in transit and at rest, with EU data-residency available and a GDPR-ready DPA. Outbound PII is SHA-256 hashed, tenant data is isolated at the query layer, and access is role-scoped — read-only seats never see PII or tokens.

Yes. Self-serve plans are month-to-month with no contracts — manage or cancel anytime from the billing portal. Your delivery history and reconciliation data stay available throughout your period.
