If you get uncomfortable, you can delete your account at any time. We'll delete your data. Not in 14 days, a week or tomorrow. That moment. We're convinced that you'll find enough value with Greplin to overcome that issue - the same way many did with mint.com.

We're also working with a) encrypted indexes b) only writing the index to disk rather then any content. this shuts down a lot of neat features (generating snippets etc.) - but users that are willing to forgo features for added security might find it useful.
