You can delete your account and everything in it yourself, at any time:
This permanently deletes your purchases, receipt files, savings history, alerts, preferences and sign-in. Deletion from our database and file storage is immediate and cannot be undone. If you want a copy first, use Profile → Export my data.
If you can no longer open the app, email privacy@digitalsummitlabs.com from the email address on your account and we will delete it within 30 days. Guest accounts have no email address, so they can only be deleted from inside the app; a guest account that is no longer used holds no contact details.
