Charges billed through Shopify
MinMaxify does not charge directly and is automatically added to your monthly Shopify invoice.
Questions about your invoices can be directed to firstname.lastname@example.org.
Once the trial period is over, Minmaxify is added to your invoice charges every 30 days and those charges appear on the next invoice after that date.
Detailed information about Shopify app charges on your invoices can be found: https://help.shopify.com/en/manual/your-account/manage-billing/your-invoice/apps#recurring-app-charges
Below is an excerpt of that Shopify information that applies to Minmaxify charges.
Recurring pricing plans
Recurring app charges are billed with the next Shopify 30-day invoice. In the example below, the bill on May 5 includes the app subscription that overlaps from April 20-May 20. The bill on June 4th similarly includes the app subscription from May 20-June 19 (since May has 31 days).
If you stop paying your bills or close your store, then Shopify freezes your account and your recurring app charges. If you start your payments again or re-open your store within 30 days, Shopify unfreezes your account, and your recurring app charges resume.
If you pause your store using the Pause plan, you don't need to uninstall your apps. Your recurring app charges are frozen while your store is on the Pause plan, but the charges resume automatically when you reopen your store, or if your store is upgraded to the Pause and Build a plan.
