Refund policy

Shopify police return and refund 

If you're asking about a Shopify return and refund policy for your online store, here's a standard example you can customize:

Return & Refund Policy
Returns

Customers may request a return within 30 days of receiving their order.

Items must be unused, in their original condition, and in the original packaging.

Some products (such as personalized, perishable, or final sale items) may not be eligible for returns.

Refunds

Once the returned item is received and inspected, the customer will be notified whether the refund is approved.

Approved refunds are issued to the original payment method.

Processing times depend on the payment provider and may take several business days after approval. 

Exchanges

Exchanges are available for defective, damaged, or incorrect items, subject to stock availability.

Return Shipping

Specify whether:

The customer pays return shipping, or

Your store provides a prepaid return label.

You may also charge a restocking fee if your policy allows it. 

How to add a return policy in Shopify
Go to Settings → Policies.

Open Return and refund policy.

Write your policy or use Shopify's template.

Save the policy. Shopify can display it during checkout, and you can also link it in your store navigation. 

If you meant something else by "Shopify police" (for example, Shopify's rules or policies), let me know and I'll explain that instead.
