Thank you for the clarification, Alistair.
Once the trial ends, we'll keep your data for a year. Your data will be deleted after that. Check out this article for more information about what happens to your data after the end of your trial period: Cancel your QuickBooks Online subscription or trial.
Once you decide to come back, here's how to resubscribe to or reactivate QuickBooks Online. If you subscribe within a year after your trial expires your data will still be available.
Let me know if you need more information about managing your subscription. I'm always glad to help in any way I can. Have a great rest of the day!
