# Why turn off Facebook and Instagram data sharing?

> Shopify's Facebook & Instagram data sharing sends Meta its own conversion events, which overlap with Upstack tracking and cause double counting — disable it so Upstack is your single source of truth.

We recommend turning off **Facebook and Instagram data sharing** in Shopify to prevent duplicate or conflicting tracking between your Meta accounts and Upstack Data.

When data sharing is enabled, Meta receives its own conversion events directly from Shopify that overlap with the events Upstack tracks and forwards. That overlap causes **double counting**, **inaccurate attribution**, and **inflated results** in your reports.

Disabling data sharing makes Upstack Data the **single source of truth** for your tracking and attribution — cleaner data in, more accurate performance insights out.

For the step-by-step walkthrough, see [Disable Facebook and Instagram data sharing in Shopify](/destinations/catalog/meta-capi/how-to-disable-facebook-and-instagram-data-sharing-in-shopify). The same principle applies to other channels — see [Disable existing tracking](/guides/migrations/disable-existing-tracking).
