The free plan can only be used to import on Shopify Dev Stores. You can import up to 5 types (products, categories) in each import. There is also a restriction of 25 products in total in your development store.

The following information is stored:

1. A mapping of commercetools product ID to Shopify product ID. This is used to efficiently import products into Collections

2. Your Shopify store email address

3. Import results and logs

4. Data entered while using the app. E.g. commercetools API client details (the secret is encrypted in the database), mappings, general settings

Existing products and collections are updated if they have previously been imported using this app. Matching is done via a commercetools-id metafield stored on each Shopify resource.

If products have been imported outside of this app then the import will fail for those products
