If you have questions or concerns regarding this statement, please contact Legal Council in Lepton’s Legal Department by calling us, emailing partnering@Leptonpharma.com or writing care of us.

This privacy policy covers only information that is collected through the Site and does not cover information that may be collected through any other means by Lepton.

Information We Collect and How We Use It

Our primary purpose in collecting personal information is to provide you with an efficient and secure way to obtain information about Lepton, such as to respond to your inquiry, send you news alerts or to consider your qualifications for a position at Lepton. We collect only personal information about you that we consider necessary for achieving this purpose. In general, you can browse the Site without telling us who you are or revealing any personal information about yourself. We may track certain information based upon your behaviour on the Site. We use this information to analyse how our Site is used.

Like many Web sites, from time to time, we automatically gather certain information about our Site traffic and store it in log files. This information includes Internet protocol (IP) addresses, browser type, Internet service provider (ISP), referring/exit pages, operating system, date/time stamp, and clickstream data. We use this information, which does not identify individual users, to analyse trends, to administer the Site, to track users’ movements around the Site and to gather demographic information about our user base. We do not link this automatically collected data to personally identifiable information.

Periodically, some pages on this web site may use “cookies,” which are small files that the site places on your hard drive for identification purposes. These files are used for Site registration and customization the next time you visit us. You should note that cookies cannot read data off of your hard drive. Your web browser may allow you to be notified when you are receiving a cookie, giving you the choice to accept it or not. You can also refuse all cookies by turning them off in your browser. By not accepting cookies, some pages may not fully function and you may not be able to access certain information on this website.

If you wish to receive information or news alerts from us, we will request your name and email address to send the information or alerts to you. We also optionally request your address, home number and company affiliation for inquiries you make under “Information Request” in the “Investor” portion of the Site.

If you no longer wish to receive our news alerts and informational materials, you may opt-out of receiving them by following the instructions included in each email notifying you of an alert or by submitting your email under the “email alert” link under the “Investors” section of the Site and following the instructions.

Conditions Under Which We Share Information

We may share aggregated demographic information about our user base with third parties that may or may not be affiliated with us, but this information does not identify individual users. We do not link aggregate user data with personally identifiable information.

We may share personally identifiable information with certain third parties on which we rely upon to operate and administer our Site and to process requests and transactions made through the Site. We disclose information as needed for these service providers to perform their functions, but do not authorize the service providers to use the information for other purposes.

We reserve the right to disclose your personally identifiable information as required by law, when we believe that disclosure is necessary to protect our rights; to protect the rights, property, or safety of other persons; to comply with a judicial proceeding, court order, or legal process served on us or the Site; or to an acquirer who purchases our Lepton or the assets to which such information pertains. We may also disclose personal information in accordance with any notice provided to you at the time such information is collected, or as you otherwise authorize.

We follow generally accepted industry standards to protect the personal information submitted to us, both during transmission and once we receive it. No method of transmission over the Internet, or method of electronic storage, is 100% secure, however, and we cannot guarantee its absolute security.

Changes in this Privacy Policy

If we decide to change our privacy policy, we will post changes to this privacy policy and other places we deem appropriate so that you are aware of what information we collect, how we use it, and under what circumstances, if any, we disclose it.
