A new update on the Closure of inactive Ubisoft accounts from Ubisoft Help has a reassurance for customers that despite indications otherwise, it will not be deleting any Ubisoft accounts with an active Ubisoft subscription or PC games purchased from the Ubisoft Store. Deleted accounts would lose access to any purchased games, so this is an important distinction. Here's word:

Inactive Ubisoft accounts, with no PC purchases or active subscriptions tied to them, may be closed in order to comply with data protection laws after long periods of inactivity.

Accounts tied to an active Ubisoft subscription, or PC games that have been purchased from the Ubisoft store, are not eligible for deletion.

We may close long-term inactive accounts to maintain our database. You will be notified by email if we begin the process of closing your inactive account.

If your Ubisoft account was flagged as inactive and you would like to keep using it, you can cancel the account closure.

You can find the cancellation link in the Ubisoft email that was sent to the email address attached to you account. If you are unable to locate this email, please check your spam folder.
