Hello @alexishongamen
Welcome to the Docusign Community!
By default, an envelope always has a Sender, in this case, you.
A sent envelope will be in your Sent folder and being updated along the recipients actions so it’s not a case to return to you, but being updated until get completed.
That said, as a Sender you can view the envelope and its contents.
Something you can do is to hide text with asterisks so the only way to you as Sender to view it is downloading as a form data. If you don’t want to keep that envelope and information in your account, just delete the envelope, but remember a deleted envelope will still at the deleted folder for 14 days until get totally purged. If your customer in the future asks for a copy, you’ll not have one anymore.
