So in both cases it’s a good idea to use another level of encryption for particularly sensitive data, despite Android itself also encrypting its file system at a low-level. Likewise backup or transfer systems may be able to be exploited. Rooted devices, for example, could circumvent Android’s usual protection and make internal data available to other apps². But under some circumstances, even that isn’t completely safe. Extra encryption, therefore, is essential for private data.¹ĭata stored to internal storage is better protected using scoped storage. If anyone knows of any apps then please let me knowĭoes anyone know of a email app that requires a pin to open it and also encrypt the emails stored on the phone?As we saw previously, the data your app stores to external storage can be read by other apps if they have the right permissions. What would be good is if it just asked for a pin/password on launching the app and once the app oped, all my files would be accessible (like some sort of vault). Now this is all well and good but its going to be a pain if I need to frequently add files to the encrypted folder.

But this recreates the original folder but still keeps the encrypted one, so when your finished you just delete the decrypted folder as you still have it in encrypted form. I'm still looking out for a better app as I'm finding the encrypt/decrypt process a bit slow and it seems that the way this app works is that you first encrypt a folder and then delete the original one, then whenever you need to access the encrypted folder you run the app and decrypt the folder. What I needed to do was click the root link and navigate to the SD card that way.

The problem was that clicking the SD card link at the top of the screen doesn't take you the the SD card. I've managed to get SSE to encrypt the files on my SD card.
