Everything you need to know
What happens to my documents if I cancel my DocFlexa subscription?
Your files remain safely in your connected Google Drive, OneDrive, Dropbox, or S3 bucket. You never lose access to your generated PDFs, receipts, or attachments.
Does DocFlexa store my cloud storage passwords in plaintext?
Never. All OAuth refresh tokens and AWS/Azure access keys are encrypted at rest using the ASP.NET Data Protection API with isolated master keys.
