Mobile travel apps are among the most popular apps to download for smartphone users – especially those apps that enable them to snag the lowest prices on travel or secure the best possible deals. However, the ease and convenience of using these travel apps to line up great deals and save money comes with a very big price for privacy and security. According to a study conducted by mobile security solutions provider Zimperium, 100% of iOS-based apps and 45% of Android-based apps failed to receive a passing grade for privacy. Moreover, 100% of iOS-based apps and 97% of Android-based apps failed to receive a passing grade for security. In short, just about any travel app you download from the Google Play or Apple Store is not going to meet basic security and privacy standards.
