One of the most popular apps on the market these days is Snapchat. It’s a lot of fun as it encourages playful and creative content, is easy to use, and it can be used as a tool to promote your personal brand. With a reported 100 million daily active users producing over 700 million snaps per day, and a growing population of adult Snapchat users, today’s Snapchat has evolved significantly since its 2011 social media debut. The app allows you to share photos and videos, draw and/or add captions if you so desire, and then share your content–or “snaps”–with followers of your choice. However, unlike Twitter or Facebook, Snapchat snaps are only available for one to ten seconds before vanishing on the receiving end. According to the platform, Shapchat “Stories” allow you to “string Snaps together to create a narrative that lasts for 24 hours,” and can be viewed an unlimited number of times within that time frame. In addition, Snapchat has its own system of emojis, filters, and editing features as well as real-time text, and video chatting that resembles FaceTime.

While people most often use Snapchat to communicate with family and friends, users also have the option to go public with their snaps. This means you can open up your snaps for anyone to view. (If you choose to do this, you’ll likely want to delete some viewers as a friend so they don’t clutter your feed, but you’ll still show up on theirs.) Many celebrities have open-to-the-public snaps; indeed, you can check in to see what a lot of actors are up to–and if you like, you can add yourself to the mix. The trend is for actors to snap humorous videos, selfies, behind-the-scenes footage, and glimpses of their personal lives.

As to Snapchat’s user privacy and safety, it’s important to know that supposedly-deleted photos from the app have reportedly been retrieved with relative ease by forensic examiners, and other users are able to take photos or screenshots of snaps you send them. So use caution as to what you send, and adjust your settings as you best see fit. After all, you are in charge of who is able to send you snaps as well as who can view yours.
