Refunds
The payment provider that charged you handles the refund.
Microsoft Store purchases
Microsoft handles refund eligibility and payment returns for the Store version. Find Vign.et in your Microsoft account order history or contact Microsoft Store Support. Its terms of sale and your mandatory consumer rights determine eligibility.
Earlier direct purchases
If your receipt came from Stripe rather than Microsoft, email hello@vignet.site and forward the receipt so the correct order can be found.
