What counts as one price change?
One successful sale-price write to one product variant counts as one change. Restoring that variant later does not count as another monthly change.
Is there a free trial? Can I get a refund?
Paid plans have no free trial. The Free plan is how you try SaleGuard, and it includes snapshot, restore and rollback. Payments are not refunded. If you cancel, you won't be charged again and you keep your plan until the end of the period you've paid for.
Can I cancel any time?
Yes. Switch to Free in the app, or uninstall. Billing runs through Shopify, and after you cancel you keep your plan until the end of the period you've paid for.
