A privacy checklist for Shopify personalization
Map every data input, purpose, and retention period before you launch. Check Shopify's processing rules, keep a working nonpersonalized experience, and test consent changes end to end.
Start with the data map
Before any tool goes live, write down every input personalization uses: behavioral events, purchase history, location, device data, and anything from third parties. For each input, record the purpose, the retention period, and where it flows. This document is the foundation of everything below; without it, the rest is guessing.
Shopify's platform rules add a layer. Customer data accessed through Shopify APIs comes with allowed processing purposes, and personalization has to stay inside them. Review the current terms, not the ones from when you installed the app.
Build the degraded experience first
Design the nonpersonalized version of every personalized surface before you design the personalized one. When consent is declined or data is unavailable, the store must still work well: useful defaults, clear navigation, no errors, no empty slots. Teams that build this first ship better personalization too, because the fallback disciplines the design.
Test the degraded experience as a first-class state, not an edge case. A meaningful share of your traffic will see it, and in some regions it is the default.
Retention, deletion, and vendor review
Set retention periods per input and enforce them. Behavioral data kept forever becomes a liability the moment a deletion request arrives, and most personalization does not need year-old clickstreams. When a customer asks for deletion, confirm it propagates to the personalization vendor, not just your database.
Review vendors annually against the data map. Ask what they collect, what they retain, and whether they use your data for their own purposes. A vendor that trains shared models on your customer data may be selling under privacy law, which changes your consent obligations.
What is the single highest-risk item?
Unmapped data flows to vendors. You cannot govern what you have not inventoried, and vendors are where most surprises live.
Does Shopify handle privacy compliance for apps?
No. Shopify sets platform rules, but your store's compliance with privacy law is your responsibility, including what your apps do with customer data.
How often should the checklist be revisited?
At launch, annually, and whenever you add a data input, a vendor, or a personalization surface.
