internal storage - What's in Chrome's data?

I'm running stock 4.1.2 on a Wolfgang AT-AS43D4 (not rooted). According to DiskUsage, I have about 755 MiB app storage in total, of which I have currently around 100 MiB free space left, so I try to keep the internal storage as empty as possible.

I see Chrome taking up 94.4 MiB, (134 MiB after the latest update) of which about 24.3 MiB is data (up to 28 MiB by now).

My question is twofold:

What is in there? What does Chrome keep there that's almost over 25 MB big?

How can I selectively clean that? I can delete the data wholesale, but I don't want to. Is there any other way? I tried various options in Chrome, but couldn't find anything useful.

Edited: a previous version of this question mentioned an insufficient memory error. This had little to do with the question; I was conflating RAM and app storage.

Answer

It contains:-

• Resource files for Chrome itself. These are really part of the app, but they're downloaded by Chrome itself so the APK doesn't need to contain all the resources for all locales, and to make them easier to update.


• Local storage for websites that use the HTML5 local storage feature. For some sites (e.g. Twitter) this can get quite large.


• All your preferences, just like any other app. This amounts to a few KB.
