Privacy

Siri enjoys delivering answers to iPhone owners whether their devices are locked or unlocked. Sometimes the call "Hey Siri" is even answered no matter who is asking. Pressing the Side button or Home button can also invoke Siri from the Lock Screen. For those who consider this a privacy or security risk, Siri can be completely disabled when the iPhone is locked.

Facebook, by default, is set up to send you notifications via SMS for just about everything that can happen - comments on posts, friend requests, birthdays, friends' updates and more. The notifications seem to be random as well, sometimes there are none for a while, then all of a sudden a flood. Depending on how active you are on Facebook, these text notifications can quickly become a nuisance. If you suddenly find yourself being bombarded with text notifications from FB, you can turn them off completely or better yet, pare them down to only what's important to you.

iPhone owners have many options when it comes to free email services. Yahoo! has been around for some time, and until recently a Yahoo! account was required to participate in the photo sharing site Flickr. For anyone who has deleted their Flickr account, or who rarely uses Yahoo Mail, there is a simple way to permanently delete your Yahoo! profile.

Flickr has changed hands many times and become less popular with the rise of photo sharing apps such as Instagram. The service recently announced changes to its free account storage limits. If 1,000 images and videos isn't enough, some users may want to purchase a Flickr Pro subscription. Others may decide to move away from the service.

Apple recently revamped its main privacy page. The portal contains various information about Apple's commitment to protecting privacy as well as the latest version of the company's Privacy Policy. Apple has also launched a new feature, making it possible for customers to download their own data from Apple's servers.
