Spero Therapeutics respects your right to privacy

Last Edited on August 24, 2022

Spero Therapeutics and its subsidiaries and affiliates (together, “Spero Therapeutics ,” “we”, “our”, “us”) are committed to protecting and respecting your privacy. The purpose of this Privacy Notice is to provide you with information on how we will collect, use, disclose, protect and otherwise process personal information and to explain the rights and choices available to individuals concerning their personal information. We are a company established in the United States with a registered Headquarters office at 1100 Winter Street, Waltham, MA 02451, and, for the General Data Protection Regulation (the “GDPR”) and similar data protection and privacy laws, we are the data controller. 

This Privacy Notice, sets out the basis on which we will process personal information we collect from you, or that you provide to us, in connection with your use of Spero Therapeutics website, including information provided by you by email (by using the email addresses on our " Contact " page of our website), Social media or online platforms hosted by Spero Therapeutics (e.g. Company page on LinkedIn or Twitter*) (together, the “Sites” and each a “Site”).

*For the use of social media, Spero Therapeutics will be joint-controller with LinkedIn and Twitter only for the following activities: accessing and processing statistical aggregate data provided by LinkedIn and Twitter in relation to Spero Therapeutics Sites. For any other processing on the platform, social media platform shall be considered as the sole data controller. LinkedIn has created an “addendum” to its user agreement for sites for the processing for which it is joint-controller with us. Such agreement is not currently provided by Twitter. 

If you have provided personal data through some means other than through our Sites (for example, in connection with a clinical study sponsored by Spero Therapeutics in Europe in which you participate), you will have received a separate notice concerning your personal data.  Please refer to that notice first if you have any concerns about our processing of your personal data, as that notice will contain important information and a designated contact person for concerns. This Privacy Notice does not cover other services that we may offer or provide, and does not cover information we receive from third parties.

By accessing the Site, you agree to be bound by this Privacy Notice.  If you do not agree to the terms, please do not use the Site.
