Web: When you sign up for any online service, you usually need to add an email address. If you usually use a Gmail account, Deseat.me can scour your email to find everything you signed up for and offer you ways to delete your account.

Android (Xposed): Last year, Google made a change to how Android permissions are handled that could allow some new privileges to slip through unnoticed. PlayPermissionsExposed is an Xposed module that fixes this so you won't be taken by surprise.

Android: A recent change to Google Play's permission system made it possible for developerss to give themselves new permissions without you even realising it in some cases. MyPermissions helps give you some control back.

Android: When Android 4.4 arrived, it remove the ability to directly access the individual permissions manager built into Android. While it's no longer available to access directly, an app called App Ops can bring it back.

We scored our first look at Android 4.3 earlier this week. While we didn't see too much that thrilled us, word of a new hidden Permissions Manager that lets you set individual app permissions has our interest piqued. The power to control each app's granular permissions is a huge boost to privacy and security.

Dear Lifehacker, I have followed your guide to building a home server with FreeNAS, but I'm not sure what to do with the permissions on my files. Can I just set them all to 777, or is that insecure? This stuff is like Chinese to me, help!

The start of the year is a good time to check which apps have access to your private information. MyPermissions makes this process very easy by linking directly to app permissions pages for popular services such as Google and Facebook.
