5 Useful Android Apps to Lock Down Your Text Messages And Images

Privacy is a concern for most people these days. Whether you are looking to keep your information private from a snooping coworker or a nosey boyfriend or girlfriend, there are apps to help. The problem is, some of the apps are just plain awful. What I will go over today are some good apps to use for keeping texts and images from being easily accessed.

Some of the apps in this list have some built in functionality for just such a task. Others may need to be unlocked by purchasing the pro version. Others yet are made specifically for hiding SMS messages or images from any prying eyes.

1. GO SMS Pro

GO SMS Pro is a really popular app. In fact, it is the one I have used off and on for couple of years. One feature I didn’t really know about was the ability to have private contacts. In a nutshell, you can take a contact, a potential employer for example, and place them in your private inbox. If they send you a text message, you will need to unlock the message before it can be read.


When you have the premium version of GO SMS Pro, you can hide the private SMS inbox from the menu and unlock more of the settings to make it more difficult to access. What I like here is the ability to rename the SMS vault inbox to something a little less conspicuous.

2. Hi App Lock

Very recently I talked about Hi App Lock. This is a good option for locking individual Android apps for better privacy. You can easily use Hi App Lock to lock down anywhere you feel an onlooker may be able to access the information you’d like to keep private. Think about how often you leave your phone or tablet on your desk or in your car or backpack unattended. If your Android device was stolen, what would people be able to see and/or do with the information they find?


Do you send messages to someone you aren’t supposed to? Are your work text messages or images you take with your work camera confidential? No reason for you to have information leaked just because you set your phone down.

3. Vault

Vault is an app that’s come a long way in the past couple of years. When I first tested it, all you could do was hide images and it wasn’t all that great at it. Now Vault has evolved into more of a privacy control center. With the free version, you can encrypt your images, you can also encrypt a limited number of text messages too.


A feature I really thought could be helpful is the option to link your Facebook account and encrypt your Facebook messages. When you send a Facebook message to someone, they will be able to read it, but the message doesn’t show up in your conversation history.

4. Secrets

Secrets is similar to Vault because you can hide images or other files. It’s different because the Secrets doesn’t show up in the Android app drawer. Opening Secrets is done by going to your phone dialer and typing the default 1111 and pressing send. You will be prompted to enter a code then you can see your hidden files. Having an app for just your images can be nice, especially when you might have taken or received some images you might not want anyone to know about.


5. Hide SMS

Hide SMS is just for hiding text messages. Hiding the messages is as simple as long pressing the message and opting to move the message to the hidden inbox. When a new message arrives, You will see an inconspicuous message in your notification bar saying KeepSafe updated. When hiding a current thread, the app may not move your images over. They didn’t on my Samsung S3.



People have many different reasons for wanting to keep their communications private. The above apps are there to help. I would recommend trying some of the all-in-one apps for an ease of use standpoint. When you have too many apps on your phone for similar tasks, it can get confusing and could even slow down or cause conflicts with each other.
