This page explains how to remove any Facebook data this application has stored on your behalf.
When you connect your Facebook account, we store only the access token issued by Facebook and the basic ad account details needed to fetch performance reporting (spend, impressions, clicks, and related metrics). We do not store passwords, private messages, or personal content from your Facebook profile.
Contact us from the address associated with your Facebook account and let us know you'd like your data removed.
All associated Facebook tokens and stored information are permanently deleted within 30 days of your request.
You can also remove this app's access at any time from your own Facebook settings, under Settings & Privacy → Apps and Websites, without waiting for a manual request.
