Sods law that I subscribed yesterday, but at least it was for the free trial!
The following info is a direct copy/paste of the email I got:
Dear Stadia player,
On September 29, 2022, we announced that the Stadia service will be shut down on January 18, 2023. We’re getting in touch with important information on what this means for you as a Stadia player.
Availability
Stadia will remain available for gameplay until the service is shut down on January 18, 2023. During this period, you will have access to your game library, including Pro games if you had an active Pro subscription as of September 29, 2022. Be aware that publisher support for games may vary, and it’s possible that your gameplay experience may be affected during the shut-down period.
Refunds
Google is offering a refund to Stadia users for Stadia hardware purchases (Stadia Controller, Stadia Founder’s Edition, Stadia Premiere Edition, or Play and Watch with Google TV Package) made on the Google Store, and game purchases and add-on purchases made on the Stadia Store. The refund process will take some time, but we expect to have the majority of refunds processed by January 18, 2023. We expect to be able to automatically issue refunds for a substantial portion of transactions as a credit to the form of payment used to make the purchase. For purchases that we are not able to automatically refund, you will receive an email with details on how to obtain your refund.
Transactions and subscription fees
All commerce functionality (the ability to buy games, new subscriptions, add-ons or in-game purchases) on Stadia has now been disabled. Users who held an active Stadia Pro subscription as of September 29, 2022 will not be charged for access to their Pro library or other subscription entitlements during the shut-down period. Historical Stadia Pro subscription fees will not be eligible for refund.
Your Stadia account and data
You will be able to export your Stadia data, such as profile information, game stats, social data, save files and captures from Google Takeout until the Stadia service shuts down on January 18, 2023, after which point your Stadia data will be permanently deleted. You can also delete Stadia from your Google account at any time or delete your Google account entirely. Please note that deleting your Google account will result in deletion of all data and content in that account, including emails, photos, and files, and may increase the amount of time it takes to receive a refund of your Stadia purchases. Google may however retain certain data, including transaction data, for up to three years following the shut-down of the service for the purposes of processing refunds and providing customer support.
More information is available in the Help Centre, which will be updated as new information becomes available.
