“What you share on Twitter may be viewed all around the world instantly. You are what you Tweet!”

The Basics

You must be 13 years or older to use Twitter.
You must provide basic information to sign up for an account. This includes:
• name
• email
• phone number, etc.

The only personal information that becomes public is your name and username. You may use a pseudonym as your name, but this is what people use to search for you later. You are in charge of safe guarding your account, so make sure you come up with a strong password when signing up.

Sharing Your Information

Twitter posts your information for few reasons, as follows:

“We may share or disclose your information at your direction, such as when you authorize a third-party web client or application to access your account or when you direct us to share your feedback with a business. When you use Digits by Twitter to sign up for or log in to a third-party application, you are directing us to share your contact information, such as your phone number, with that application. If you’ve shared information, like Direct Messages or protected Tweets, with another user who accesses twitter through a third-party service, keep in mind that the information may be shared with the third-party service.”

They can still share your public information with whomever they please.

To help personalize your experience, you can provide Twitter with additional information, such as access to your contact book. This makes it easier to locate friends that may also be using the application. You can also include your shipping address if buying a service from Twitter. This is deemed private information and Twitter claims to not share it.

“Twitter is primarily designed to help you share information with the world. Most of the information you provide us through Twitter is information you are asking us to make public.”

Make sure to pay attention and be cautious of what you make public- whether they are pictures, videos of links. Not only are they viewable by the general public, but Twitter also uses them to determine topics you may be interested in.

“What’s yours is yours.”

What you post is still yours. You own your content whether it be photos, videos, or other forms of content. However, when you post those items, you grant the world access to steal your post royalty-free and do whatever they choose to with it. Consequentially, this may mean your images or likeness may be used on ads and/or websites you do not want to be associated with nor gave direct consent to.
Finally, understand that you do not need an account for Twitter to store your information. All you have to do is interact with any part of their services.
