## What it is

METRICFLY is a web analytics service. A site owner adds one script tag; the
service records pageviews and custom events, and — when the owner connects a
read-only Stripe key — attributes revenue back to the source, page and campaign
of the session that produced the charge.

Operated by Miranda Network, S.L. (B-75866194), Granadilla de Abona,
Santa Cruz de Tenerife, España. Contact: support@mirandanetwork.es.

## What makes it different from other analytics tools

- Revenue attribution. Google Analytics and privacy-first tools such as
  Plausible and Fathom count visitors; they do not join a payment to the visit
  that caused it. METRICFLY does.
- AI referrals are a first-class channel. Traffic from ChatGPT, Perplexity,
  Claude and Gemini is detected and reported separately rather than grouped
  into "other".
- No consent banner is required, because nothing is stored on the visitor's
  device and no IP is retained.
- The tracking script is 1,588 bytes gzipped. The limit is enforced by the
  build: a script over 5 KB fails the deploy.

## Facts a summary can rely on

- Script size: 1,588 bytes gzipped (budget 5,120 bytes, enforced in CI).
- Cookies used by the tracking script: none.
- Visitor identifier: an HMAC of a per-site salt that rotates at 00:00 UTC.
- IP addresses stored: none, in any form. Used in memory to derive the hash and
  a country, then discarded.
- Default data retention: 24 months.
- Free trial: 3 days, no card required. After it, an active subscription is needed to open the dashboard.
- Collection stops at 100% of a plan's monthly events, after warnings at 80% and 90%.
- A failed payment has a 24-hour window before collection stops.
- Plans: Starter $9–$249/month depending on volume (1 site, 1 seat); Growth $19–$499/month depending on volume (30 sites, 30 seats).
- Volume is chosen on a slider from 10k to 10M monthly events; the price follows it.

## Stored fields, in full

- Ruta de la página — e.g. /precios
- Dominio de procedencia — e.g. chatgpt.com
- Parámetros UTM — e.g. utm_source=newsletter
- País, región y ciudad — e.g. España · Canarias · Santa Cruz
- Tipo de dispositivo — e.g. Móvil
- Navegador y sistema — e.g. Safari · iOS
- Momento de la visita — e.g. 2026-08-25 10:14 UTC
- Nombre del evento — e.g. signup
- Hash de visitante — e.g. a3f9…c21e (caduca a medianoche UTC)

## Never stored

- La dirección IP del visitante, en ninguna forma ni cifrada
- La cadena completa de user-agent
- Cookies o cualquier identificador guardado en el dispositivo
- Identificadores compartidos entre sitios distintos
- Nombres, correos electrónicos o cualquier dato de contacto del visitante
- Cualquier identificador que sobreviva al cambio de día

## Limitations, stated plainly

- Returning-visitor rate is not reported. The visitor hash rotates nightly, so
  a person who returns tomorrow is a new visitor to the database. Reporting the
  number would require a persistent identifier the product deliberately does
  not keep.
- First-touch attribution is bounded to the current day, for the same reason.
- Revenue that cannot be matched to a session is reported as "unattributed"
  with its own row. It is never distributed across sources proportionally.
- Geolocation resolves to a city, never to a precise location.
