I have a question/concern regarding app charges and billing

Shopify manages all app charges and billing cycles according to their policy here.

Please note the following:

  1. No need to update us on any payment info changes (e.g Changing your paying credit card) - Loox is automatically updated once changes are made on Shopify's end.
  2. Uninstalling and reinstalling Loox outside of your trial period might cause Shopify to charge you twice, as a new charge is triggered whenever Loox is installed.
  3. To the best of our knowledge, Shopify charges merchants that have upgraded or downgraded their plan a prorated amount depending on how far into their billing cycle they were when upgrading/downgrading.
  4. For any further information regarding app charges and billing, we suggest contacting Shopify's billing support team at [email protected]
