Terms and Conditions
LeetCode, LLC ("we", "us", or "our") provides this Terms and Conditions to inform you of our policies and procedures regarding the collection, use and disclosure of personal information we receive from users of our website located at www.leetcode.com (the "Site") and our mobile application (the "Application") (the Site and Application are collectively referred to as the "Services"). This Privacy Policy applies only to information that you provide to us through the Services.
INFORMATION COLLECTION: PERSONALLY IDENTIFIABLE INFORMATION
In the course of using the Services, we collect personally identifiable information, such as your name, email address, postal address, phone number, and payment information ("Personal Information") that you voluntarily provide to us when you register with the Services, express an interest in obtaining information about us or our products and services, when you participate in activities on the Services, or otherwise when you contact us. We may also collect certain information automatically when you use the Services, including your IP address, browser type, device information, and usage patterns.
COOKIES AND OTHER TECHNOLOGIES
Like many websites and applications, we use "cookies" to collect information. A cookie is a small data file that we transfer to your computer's hard disk for record-keeping purposes. We use cookies for two purposes. First, we utilize persistent cookies to save your login information for future logins to the Services. Second, we utilize session ID cookies to enable certain features of the Services, to better understand how you interact with the Services and to monitor aggregate usage by users and web traffic routing on the Services. Unlike persistent cookies, session cookies are deleted from your computer when you log off from the Services and then close your browser. You can instruct your browser, by changing its options, to stop accepting cookies or to prompt you before accepting a cookie from the websites you visit. If you do not accept cookies, however, you may not be able to use all portions of the Services or all functionality of the Services.
HOW WE USE YOUR INFORMATION
We use the information we collect to provide, maintain, and improve our Services, to process your transactions, to send you technical notices, updates, security alerts, and support and administrative messages, and to respond to your comments, questions, and customer service requests. We may also use your information to send you marketing communications, but you can opt out of receiving these communications at any time.
INFORMATION SHARING AND DISCLOSURE
We do not sell, trade, or otherwise transfer your Personal Information to third parties without your consent, except as described in this Privacy Policy. We may share your information with service providers who perform services on our behalf, such as payment processing, data analysis, email delivery, hosting services, and customer service. These service providers are contractually obligated to keep your information confidential and use it only for the purposes for which we disclose it to them.
DATA SECURITY
We implement appropriate technical and organizational security measures to protect your Personal Information against unauthorized access, alteration, disclosure, or destruction. However, no method of transmission over the Internet, or method of electronic storage, is 100% secure. While we strive to use commercially acceptable means to protect your Personal Information, we cannot guarantee its absolute security.
YOUR RIGHTS AND CHOICES
You have the right to access, update, or delete your Personal Information at any time. You can do this by logging into your account and updating your profile information, or by contacting us directly. You may also opt out of receiving marketing communications from us by following the unsubscribe instructions in those communications or by contacting us.
CHANGES TO THIS PRIVACY POLICY
We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last Updated" date at the top of this Privacy Policy. You are advised to review this Privacy Policy periodically for any changes. Changes to this Privacy Policy are effective when they are posted on this page.
