Sinister Diesel takes great pride in having you as a customer and we will ensure your privacy as a customer. Sinister Diesel does not sell or exchange names or any other information about our customers with third parties.

We may disclose any information, including personally identifiable information, we deem necessary, in our sole discretion, to comply with any applicable law, regulation, legal process or governmental request. We may also exchange information, including personally identifiable information, with other companies and organizations for credit fraud protection and risk reduction.

We may retain other companies and individuals to perform functions consistent with our Privacy Policy on our behalf. Examples include customer support specialists, web hosting companies, fulfillment companies (e.g., companies that fill product orders or coordinate mailings), data analysis firms and email service providers. Such third parties may be provided with access to personally identifiable information needed to perform their functions, but may not use such information for any other purpose.

By choosing to participate and submitting your personally identifiable information, photos, or other materials with respect to such events or promotions, you consent to disclosure of your personally identifiable information along with the submitted materials to such third parties.

As we continue to develop our business, we might sell certain of our assets. In such transactions, user information including personally identifiable information, generally is one of the transferred business assets. By submitting your personal information to Sinister Diesel, you agree that your data may be transferred to such parties in these circumstances.

We may place a "cookie" on your computer's hard drive so we can recognize you as a return user and personalize your experience. A cookie is a piece of data that enables us to track and target your preferences. The cookie will be stored on your computer's hard drive until you remove it. We may also use temporary or "session" cookies to help you shop. These cookies will expire when you place an order. You can have your browser notify you of, or automatically reject, cookies. If you reject our cookies, you may still use the Site, but you may be limited in the use of some of the features. In addition, we may use IP addresses to analyze trends, administer the Site, track traffic patterns, and gather demographic information for aggregate use, as well as in combination with your personally identifiable information for credit fraud protection and risk reduction.

Similarly, when you visit this Site or view one of our emails, we may use pixel tags (also called "clear" gifs), tracking links and/or similar technology to note some of the pages you visit on our Site and personalize your experience. We may also use pixel tags to determine what types of email your browser supports. We may use the information collected through pixel tags, tracking links and similar technology in combination with your personally identifiable information.

sinisterdiesel.com does recognize your ISP (internet service provider), however, we cannot identify you as an individual. If you make an on-line purchase we do collect information (such as sales statistics and traffic patterns) to help improve your shopping experience. We keep all information confidential.

We may use the information you provide in aggregate (non-personally identifiable) form for internal business purposes, such as generating statistics and developing marketing plans. We may collect, store or accumulate certain non-personally identifiable information concerning your use of the Site, such as information regarding which of our pages are most popular. We may share or transfer non-personally identifiable information with or to our affiliates, licensees and partners.

Our Site may contain links to or from other websites and you should be aware that we are not responsible for the privacy practices of other websites. We encourage you to read the privacy policies of other websites linked to the Site.

Sinister Diesel seeks to protect the security of your personal information both online and offline. All credit card transactions are secure. Every on-line order is encrypted and sent through a secure server, using SSL technology to prevent information from being intercepted.

Confidential information such as your credit card number will be used only to fulfill your order. To protect your privacy, we will ask you to enter your credit card number and expiration date each time you place an order with us. This way, even if someone else accesses the account information stored on your computer, they won't be able to use your credit card.

E-mail is not encrypted and is not a secure means to transmit credit card numbers. We will only display the last 4 digits of your credit card number on your account.

Sinister Diesel reserves the right to revise this Privacy Policy in the future by posting changes at this location and we may make changes at any time without notification.
