Everyone at GOG believes in a 'gamers-first’ approach. It means that every part of our store is designed with gamers in mind and your purchase safety and satisfaction come first for us. The latest update to our voluntary Refund Policy adds another piece to this customer-friendly experience. And it all sums up in one sentence:
starting now, you can get a full refund up to 30 days after purchasing a product, even if you downloaded, launched, and played it. That's it.
The updated policy lets you refund a product up to 30 days after purchase, even if it was downloaded, launched, and played. Yes, you read that correctly.

To apply for a refund, you should
contact our Customer Support Team within 30 days of your purchase, and our team will sort it out as soon as possible.
However, if the reason you are seeking a refund is that your game is not working (yet!), please consider
contacting our friendly Tech Support folk first. They will do their best to help you get the game working on your machine.
We're monitoring the effects of the current update to make sure no one is using this policy to hurt the developers that put their time and heart into making great games. We may refuse refunds in such individual cases. We'd also let you know about any future adjustments in the voluntary Refund Policy in advance.
