>app's private data folder

That may be the problem. WhatsApp has focused since the beginning on making their app available on as many devices as possible (They even have symbian compatibiity).

My WhatsApp database is almost 500MB, this is more than many low end Android phone's internal memory. Therefore, they decided to store the database on the SD card.

I don't think that this should be a problem had they decided to implement proper encryption on the database.

I'm not an expert and this is just pure speculation, so please, take as it is.




Did you read the post? You only need to store the key in private data. A few bytes at most.


Yes, I did, I wouldn't be replying if I hadn't. But I was replying to the parent comment.

>Which is where the database should have just been stored in the first place, and not on the public SD card

I was just guessing why WhatsApp may have decided to put the database on the SD card. But maybe I didn't understand what kllrnohj was referring to when he said "database".

EDIT: Also, that's why I said:
