Move app data (on /data/data) to SD card I bought one of those budget phones that claimed to have 4GB of internal storage, but it looks like there is only 1.08GB. I don't know why it says that I only have 1.08GB if I already used 1.12GB for apps.

I removed all bloatware and moved all my APKs to the SD card, but I still don't have enough space for Google Docs, etc.
The main culprits are SpanishDict and Facebook, which take up 200MB of internal storage each (at /data/data/com.spanishdict.spanishdict and /data/data/com.facebook.katana)
Of course, I googled before asking and such, and I used this program called FolderMount. But it doesn't seem to work well with moving things outside of the SD card, defeating the whole purpose of it.
Does anyone know a way to actually move app data from the internal storage to the SD card?
Btw, I am using a Lanix X200.
TL;DR no space on the internal store because of app data on /data/data. Need to move it to an SD card.
First, when they say there is 4 GB storage, they count all partitions, so there is 4 GB on your phone.
To move data to an SD card, you will have to use an app called Link2SD (root required) or use an adoptable storage feature (Android 6+ only). In both cases, you don't move folders manually if you do that you will probably screw up something.
Also, if you really need a Facebook app, use the lite version, or access it via a browser. The normal version uses too much space and too many resources. Generally, I say this because I assume you don't have more than 768 MB of RAM, so use it wisely.
