Audit logs for Sharing of Notebook

I just found that one of my notebooks was shared out that I didn't recall sharing. Using personal/free version is there a way to see when and how it was shared?

There is no bookkeeping over the shares. You can try to find the email that was send with the sharing in your email program.

To control the share, revoke it.

If a whole notebook was shared, you can either revoke the sharing, or you remove the notes you want to stop sharing from the notebooks. Once removed the sharing for these notes is stopped immediately.

..And recently someone reported something similar that involved IFTTT having processed some notes that incorrectly showed as 'shared'.  Do you use IFTTT or any other third party services?
