You have 7 days from your first payment to request a full refund, no questions asked. Contact the developer within that window and it's processed directly.

Payments are final. You can still cancel any time to stop future billing; your current paid period just stays active until it ends, same as any subscription.

Refund requests go through the Mosaic Discord or mosaicplugin@gmail.com, read directly by the maker of Mosaic.
