How does YUEN connect to my ad account?
Through the official OAuth consent screens of Google Ads and Meta: you approve with your own account, and YUEN receives only ad read/manage and page-statistics permissions. Your password never reaches YUEN at any step.
How do I revoke YUEN's access?
With one click in Portal → Connections → "Remove connection". The access key is deleted immediately and revoked on the Google/Meta side as well; ownership of the account always stays with you.
Where and how are access keys stored?
Keys are stored encrypted with AES-256-GCM in the EU (Frankfurt); only the server reads them and nothing reaches the browser. Every client's data is isolated at row level; AI recommends, a human approves each change, and every action is logged.
