New purchases of ToggleWP come with a 14 day satisfaction guarantee. If you aren’t happy with how the plugin works you can request a full refund. Ideally I would like to understand why you would like a refund, if its due to compatibility issues or expected functionality. This will help ToggleWP become a better product.
How about refunds on annual renewals?
Freemius will email you one month before your renewal date. If you do not wish to renew please cancel your subscription via the Freemius portal before being charged. Refund requests after you have been charged will be refunded minus gateway fees.
