Cool project. I wonder how it persists after clearing browser history/cookies/LocalStorage.

It doesn't: "Data is stored reliably but can also be voluntarily purged if the user designedly clears cookies and application storage".

Then that’s inconsistent with the beginning of their readme:

> For example, clearing cookies is a common user action, even for non-technical users. And browsers will unceremoniously delete IndexedDB, LocalStorage, and/or SessionStorage without warning under storage pressure.

> ImmortalDB is resilient in the face of such events.

I guess that’s a good thing. I was worried about the next browser supercookie being made with a library like this.

It's based on Evercookie https://github.com/samyk/evercookie which is a little less... friendly.
