How does your product ensure privacy?

In other words: how does your product make sure people aren’t going to abuse it by distributing unique copies of their workbooks so they can track the exact times of individual recipients looking at them?

Yeah - great point. I'm actually working on a way to detect if a set of IDs are being used on the same workbook. This is possible technically via some environment variables inherent to the spreadsheet - but it opens up another can of worms on the privacy side of information I'd have to collect.

I think the short-term solution will be to throttle unique ID creation to 5 / email - not perfect, but I'm a one-man team so will have to bite at this problem step-wise :)
