Fourteen days, no reason needed.
Go to paddle.net and find your order with the email address you paid with. Paddle handles it from there.
Or write to billing@voxi.live from that same address and a person will pick it up.
Fourteen days from the purchase, for any reason at all.
After that, ask anyway if something went wrong. A purchase that did not work is not a change of mind.
Vibes are spent as you use them, so a refund is worked out against what is left.
Paddle is the merchant of record for everything sold on Voxi.Live. They take the payment, collect and remit the tax, and handle refunds and chargebacks. Voxi.Live appears next to Paddle on your statement, and Paddle's buyer terms cover the sale itself.
