My Results: How Is Data Shared?
Communicate About Privacy
Request privacy from companies and services that have data about your offline activities, such as healthcare, banking, insurance, and utility providers. Specifically, opt out of sharing your information with third parties. Use these guides to help you navigate opt-out procedures:

Learn About Online Privacy
Check out apps, sites, and services before you use them. Read the privacy policy; if you don't like what it says about what the provider will do with your data and who they may share it with, you can do business with a different provider (even if it means paying slightly more—a "privacy premium").

Manage Your Profiles
If an app or site asks for your personal information, weigh the benefits before giving it.
- Ask yourself: Do they really need this information to provide the service? What permissions are they asking for and do they really need access to that information?
- If you don't know how an organization or service will use your information—either because they don't say or because their privacy policy is too unclear for you to read—consider not giving it to them, or at least limiting what information you give them.
- Don't fill in non-required fields.
- You may be able to give false information in the required fields if it's not necessary to the service you're getting. However, you should check the provider's terms of service first to make sure they do not require that your personal information be correct. Don't give false information to banks, government agencies, and other highly regulated services, as it may be illegal.
