Android - Location of Chrome user data (Specifically session data)

App data usually go below /data/data/<package_name> (in case of Chrome: /data/data/com.android.chrome). But those directories are only accessible by the app itself, and by the system/root – so unless your device is rooted, you won't have much luck checking there.

Concerning the file-system hierarchy, you might wish to first consult the file-system tag-wiki, and then follow up to Android Folder Hiearchy.

Good news and bad news. Good news: Izzy's right; bad news: it probably won't help much.

I found my open tab info under /data/data/com.android.chrome/app_tabs/0. But they don't seem to be stored per-session, oddly; instead, each tab has its own file (numbered sequentially, file name tabN, N=tab number), and there's one additional file tab_state that seems to hold metadata. No single session file, no session backups, nothing like that that I've been able to find.

Hopefully I'm wrong and I just haven't looked everywhere, but this is all I could find as far as tab info goes.
