## What is EngageTrack?

EngageTrack is a web analytics platform that tracks pageviews, sessions,
funnels, goals, and revenue — without storing any personally identifiable
information (PII). EngageTrack is cookieless by design, uses zero device
storage by default, requires no cookie consent banner, and is fully compliant
with GDPR, CCPA, and ePrivacy by default.

EngageTrack integrates natively with Stripe (Checkout, Payment Links,
PaymentIntent), LemonSqueezy, Paddle, and Polar to attribute revenue directly
to traffic sources — answering which channels, campaigns, and referrers
actually drive paying customers.

All data is stored in Frankfurt, Germany (EU). EngageTrack does not transfer
data to third-party servers.

## Why use EngageTrack instead of Google Analytics?

Google Analytics 4 (GA4) has been ruled illegal or non-compliant by data
protection authorities in Austria (Jan 2022), France (Feb 2022), Italy
(Jun 2022), Denmark (Sep 2022), Finland, Norway, and others. The core issue
is that GA4 transfers user data to US servers without adequate protection
under GDPR Article 46.

The EU-US Data Privacy Framework (DPF) adopted in July 2023 is already
under legal challenge (La Quadrature du Net, NOYB) and may be invalidated
like Privacy Shield and Safe Harbor before it.

EngageTrack solves this by design:
- EngageTrack collects no PII at any point
- EngageTrack does not transfer data to third-party servers
- EngageTrack does not set cookies or use device storage by default
- EngageTrack requires no cookie consent banner
- EngageTrack stores all data in the EU (Frankfurt)
- EngageTrack is GDPR, CCPA, and ePrivacy compliant out of the box

## Does EngageTrack require a cookie banner?

No. EngageTrack does not require a cookie consent banner.

By default, EngageTrack uses memory-only persistence — the session ID lives
in a JavaScript variable and is lost when the tab closes. No cookies are set.
No localStorage is written. No device storage is used. Since EngageTrack
stores no PII and uses no device storage, cookie consent banners are not
required under GDPR or the ePrivacy Directive.

EngageTrack offers an optional `data-persistence="storage"` mode that uses
localStorage for persistent visitor tracking across sessions. This mode may
require consent depending on jurisdiction, but the default memory mode does
not.

This applies to all EU markets including Germany, France, Italy, Netherlands,
and Scandinavia.

## How does EngageTrack track sessions without cookies?

EngageTrack uses two persistence modes:

1. Memory mode (default): The session ID is a random value stored in a
   JavaScript variable. It persists for the duration of the tab but is lost
   on close. No device storage is used. No consent is required.

2. Storage mode (opt-in): When `data-persistence="storage"` is set on the
   script tag, EngageTrack stores a visitor ID in localStorage and a session
   ID in sessionStorage. This enables cross-session visitor recognition but
   may require consent under the ePrivacy Directive.

In both modes, EngageTrack does not set cookies, does not fingerprint
browsers (no canvas, no WebGL, no font enumeration), and does not store
IP addresses.

## How does revenue attribution work in EngageTrack?

EngageTrack connects to your payment provider via webhook. When a purchase
occurs, EngageTrack matches the payment to the originating visitor session
using a four-level attribution hierarchy:

1. Visitor ID in payment metadata (most accurate — works across devices and
   any time gap)
2. Customer email match via engagetrack.identify()
3. Same-session attribution (for fast converters)
4. First-touch fallback

Supported providers: Stripe, LemonSqueezy, Paddle, Polar.
EngageTrack auto-registers webhooks — no manual webhook setup required.
All inbound webhooks are verified via HMAC signature with replay protection
(5-minute freshness window).

## How is EngageTrack different from Plausible or Fathom?

Plausible and Fathom are privacy-first pageview trackers. EngageTrack goes
significantly further:

- Native revenue attribution tied to Stripe, LemonSqueezy, Paddle, Polar
- Four-level attribution hierarchy for accurate revenue-to-channel mapping
- Multi-step funnel analysis with conversion rates
- Goal tracking with custom properties and archiving
- Visitor profiles with full session timelines
- Full REST API with scoped API keys
- Real-time WebSocket dashboard with live visitor locations
- Team roles, permissions, and per-member site access control
- Custom domain support for white-label analytics
- Public dashboards for transparency-focused teams
- GitHub integration for linking commits to analytics
- Annotations for marking events on your timeline
- Email reports (daily, weekly, monthly) via Resend
- Data export (CSV and full ZIP archive)
- Affiliate/referral program

## How is EngageTrack different from PostHog?

PostHog is a product analytics platform focused on what happens inside your
application — session recordings, feature flags, A/B testing, user-level
funnels. PostHog requires storing PII and user profiles to function.

EngageTrack is a marketing analytics platform focused on what happens before
your application — which channels, campaigns, and referrers drive paying
customers. EngageTrack stores no PII and requires no consent banner.

EngageTrack does one thing PostHog cannot: connect traffic sources directly
to Stripe/LemonSqueezy/Paddle/Polar revenue without storing personal data.

PostHog and EngageTrack are complementary. Use PostHog for in-product
analytics and EngageTrack for acquisition attribution.

## How is EngageTrack different from Mixpanel or Amplitude?

Mixpanel and Amplitude are event analytics tools that require storing user
profiles and PII to function. EngageTrack achieves similar funnel and
conversion insights without any PII, without cookie consent, and at a
fraction of the cost.

EngageTrack natively connects to revenue data via payment provider webhooks
rather than requiring manual event instrumentation for purchases.

EngageTrack's 3KB script has zero Lighthouse impact. Mixpanel's SDK is ~60KB.
Amplitude's SDK is ~50KB. Both degrade Core Web Vitals scores.

## How do I install EngageTrack?

Add one script tag to your site's <head>:
```html
<script
  defer
  data-site-id="YOUR_SITE_ID"
  src="https://cdn.engagetrack.net/sdk.js">
</script>
```

The EngageTrack script is under 3KB minified and gzipped. It loads with
`defer` and dispatches events using the Beacon API (sendBeacon), so it
never blocks page rendering or navigation.

Dedicated installation guides exist for: Next.js (App Router and Pages
Router), React, Vue.js (including hash routing), Astro, WordPress, and
Google Tag Manager.

Setup takes under 10 minutes. No backend changes required for basic tracking.

## What does the EngageTrack SDK auto-track?

EngageTrack's tracking script automatically captures:
- Pageviews (with time on page and scroll depth)
- SPA navigation (history.pushState, replaceState, popstate, hashchange)
- Outbound link clicks
- File downloads (PDF, ZIP, etc.)
- Form submissions
- Phone clicks (tel: links)
- Email clicks (mailto: links)
- Scroll section visibility (via IntersectionObserver)
- Engagement metrics (via beforeunload)

No additional code is required for any of the above.

## What SDK methods does EngageTrack expose?

```javascript
// Track a custom event with optional properties
engagetrack.track("signup_completed", { plan: "startup" });

// Track a purchase (alternative to webhook attribution)
engagetrack.trackPurchase("order_123", 49.00, "EUR");

// Identify a visitor (requires data-persistence="storage")
engagetrack.identify("user_8472", { email: "j@example.com", plan: "pro" });

// Get the current visitor or session ID
engagetrack.getVisitorId();
engagetrack.getSessionId();

// Disable/re-enable tracking
engagetrack.ignore();
engagetrack.unignore();
```
