The most-used way of protecting your personal data on your Windows Phone 7 is setting up the universal password, but that might not always be the thing you need. Sometimes, it becomes necessary to have an extra layer of protection for your privacy, specially for sensitive data like photos and notes. There are many apps which let you do that, like Private Video, but what if you don’t want to make it too obvious that you are trying to hide something? Luckily, there’s an app for that, named Calculator Safe. Using this app, you can protect your photos and notes, and anyone who launches the app will see nothing but a simple calculator.
Calculator Safe provides triple layers of security. First of all you have to choose a new pass key upon the app’s launch. You are only allowed to pick a numeric combination, as the app’s password input area is a fully functioning calculator. The passcode you select can be entered in the calculator straight away, and tapping the = key will take you to the protected area, while another way of opening it is to perform a calculation which amounts to the set password. The app adds an extra layer of security, titled Secure Password, and you have to enter it again even if the app goes into lock screen. This password can be different from the first one, and allows alphanumeric values.
Calculator Safe lets you store photos and notes within the app. Notes cannot be imported to it, and you can just write or copy/ paste text in the app’s own text editor. However, for photos, you can hit the import button, and then choose any image stored in the Pictures hub.
Calculator Safe is a pretty nice app, and you can get it for free by heading to the web Marketplace link below.
