Subscriptions are for parents and adults; managed child profiles share their guardian’s plan and daily tutor allowance. If a plan ends, existing child profiles and your progress are kept; you just can’t add more beyond your plan’s limit. Downloading or deleting your personal data is always free, from your account settings.
