We’re all guilty of downloading a popular app because it was recommended or because of its high user ratings. Most of the time, we download apps without paying much attention to permission requests and are unaware of what we’re actually consenting to. You can never be too careful with your personal data.

If an app-developer is ill-experienced, rushed the coding, or is not careful, those apps are vulnerable to even the most basic hacks. Insecure apps can expose your personal information, such as your address book, location, messages, phone log, etc. Perhaps the most recent app-attack was with “Yo” last week. Three college students hacked into the app and could have stolen a plethora of sensitive information from the targeted phones.

Here are 3 expert tips to avoid an app-attack.

1. Be on the look-out for Greedy Apps. Be careful of how much information you need to give for the app. Apps vary in what information they require in order to function. For instance, Facebook asks for your email. On the other hand, the “Yo” app requires your telephone number. In this instance, providing your telephone number is more hazardous than your email because control and replacement of a leaked number can be a long, tedious project to handle.

2. If an app asks for your information, make sure it explains why. Sometimes people gloss over the permission requests, other times, apps don’t ask for permission. App developers are held responsible for explaining why they need certain data.

3. Know how to delete an unwanted app. You should never have to send an email in order to delete an app. Ideally, under your phone’s “settings,” you should be given an opportunity to delete or “remove” the app. Any other method of deletion may be a sign of insecurity.
