Our user deletion is GDPR compliant. This means that a deleted user is removed whenever possible, e.g. from shared projects, as a part assignee, etc. When the deleted user was the author of orders, parts, etc, the user will be anonymized, i.e. the part author will be listed as “Deleted User”.
Orders and order documents (e.g. invoices) remain in place unchanged to comply with Services' legal obligations of retaining those records.
