Looks really nice. Kudos. I've been looking for something like this.

Question:

1) Is it OSS?

2) Do you have a privacy statement?

I ask because - and I understand you're not Amazon, etc. - I don't like the idea of my reading habits being tracked. I would presume, you're not interested in that either. But seeing it in writing, and knowing the code is auditable isn't a bad thing either.

Again, well played.
