If something went wrong at checkout, or Plus did not unlock on this device, email the address on your Stripe receipt. Include the email you paid with. We refund genuine failures.
Change-of-mind refunds within 14 days are usually granted while the product is new. After that, Australian Consumer Law still covers products that are not as described or not fit for purpose.
A refund does not instantly clear every device. Restore and new checkouts follow Stripe: if the charge is refunded, Plus will not restore on a new device.
