Task history is stored for 30 days after tasks are completed for paid plans, and 7 days after tasks are completed for free plans. After that, task history is scheduled for permanent deletion from our servers. For example, if you schedule a task for 60 days from today, it will be deleted in 67 days on the free plan (60 days until completed + 7 days until deleted), and 90 days on the paid plan (60 days until completed + 30 days until deleted). Recurring schedules are never deleted automatically, just the tasks that they spawn. You can view the Task history by clicking on the Task in the dashboard.
