This page describes exactly what Arnio collects from visitors to your Shopify storefront, how that data is stored, and how it is used. It is written for merchants reviewing Arnio before installation, and for procurement and legal teams conducting a vendor review.
Arnio's tracking script is installed on the merchant's storefront. It collects Shopper Engagement Signals, which are Behavioral Data that help identify high-intent shoppers. Arnio does not collect payment information, passwords, or any sensitive personal data.
The following Shopper Engagement Signals are collected by Arnio's tracking script on merchant storefronts.
| Data Point | Description | Purpose |
|---|---|---|
| Visitor ID | Anonymous persistent identifier stored in localStorage | Recognize returning visitors across sessions |
| Session ID | Anonymous session-scoped identifier stored in sessionStorage | Track activity within a single visit |
| Pages Viewed | List of storefront pages visited during a session | Understand browsing depth and engagement |
| Product Views | Products viewed during a session | Identify product-level interest |
| Collection Views | Collections or categories browsed | Identify category-level intent |
| Cart Activity | Items added, removed, or abandoned in cart | Detect purchase intent signals |
| Checkout Activity | Checkout initiated or abandoned | Detect high-intent behavior |
| Traffic Source | Channel attribution (Meta, Google, TikTok, etc.) | Attribute visitor origin by channel |
| UTM Parameters | Campaign tracking parameters (utm_source, utm_medium, etc.) | Attribute session to a specific campaign |
| Referrer | Referring URL for the session | Attribute visit to its origin source |
| Ad Click IDs | GCLID, FBCLID, TTCLID, and equivalent identifiers | Attribute paid traffic to specific ads |
| Country | Derived from IP address. IP address is not stored. | Geographic attribution |
Arnio does not collect the following:
Arnio currently uses browser storage rather than cookies. No tracking cookies are set by Arnio's script.
| Name | Purpose | Storage Type | Retention |
|---|---|---|---|
| arnio_vid | Anonymous visitor identifier | localStorage | Persistent until browser data is cleared by the user |
| arnio_sid | Anonymous session identifier | sessionStorage | Session only, cleared when the browser tab is closed |
Neither identifier is linked to a named individual until an authorized identity signal is received from an approved source.
Visitors remain anonymous until Arnio receives an authorized identity signal. Arnio does not infer, guess, or purchase identity.
When an authorized signal is available, Arnio associates the session's Shopper Engagement Signals with the identified profile, within the merchant's account only.
Authorized identity signals include:
A shopper identified in one merchant's account is never used to populate another merchant's account. Identity resolution is scoped to the merchant from whose storefront the data was collected.
When a shopper meets the merchant's routing criteria (minimum intent score and any other configured thresholds), Arnio adds them to the merchant's designated Klaviyo list and attaches Behavioral Data properties to their Klaviyo profile.
Properties sent to Klaviyo may include:
Arnio does not create campaigns, modify flows, send emails, or take any action within Klaviyo other than adding a profile to the merchant's designated list and updating that profile's behavioral properties.
Merchant Data and Shopper Engagement Signals collected by Arnio are used solely to provide the Arnio service to the merchant whose storefront generated the data. Merchant Data is never:
Aggregated, anonymized platform analytics (system performance metrics, error rates, and aggregate feature usage) may be used to improve platform reliability, security, and performance. This data cannot be used to identify individual merchants or shoppers.
