Our Privacy and Security Principles We build privacy that works for everyone. It's a responsibility that comes with creating products and services that are accessible for all. We look to these principles to guide our products, our processes, and our people in keeping our users' data private, safe, and secure.

You may not use the Google search service to sell a product or service, or to increase traffic to your Web site for commercial reasons, such as advertising sales. If you want to make commercial use of the Google search engine, please contact bizdev@google.com for information on Google's services.

Privacy Policies vs. Terms and Conditions. The difference between a privacy policy and terms and conditions is that a privacy policy protects your users' rights, while terms and conditions protect your website or app's rights.

Signing in to your Google Account is the best way to access and control privacy settings and personalize your Google experience. Sign in to adjust what information you make public and what data Google can use to give you better recommendations and faster results.
