You can delete your Streak Rewards account (by Conscious Humans Studio) and all its data at any time.
Your account is deleted straight away and you're signed out.
Email support@conscioushumansstudio.com with the subject "Delete my account", from the email address you sign in with. We'll confirm and delete your account within 7 days.
This can't be undone. Copies in our encrypted backups are removed automatically within 30 days.
Nothing that identifies you. Apple and Google keep their own purchase records under their policies.
Deleting your account doesn't cancel your subscription. Cancel first in your App Store or Google Play subscription settings so you're not charged again. See Support for how.
