Reactome is an open-source, open access, manually curated and peer-reviewed pathway database. The Reactome website is administered by the Ontario Institute for Cancer Research.   This Privacy Notice sets out how we collect, store and use your personal information that you provide when you use our website or contact us. 

Collection and Use

Aggregate information is information from which individual user identities or characteristics have been removed. When you browse or download information from the Reactome website, our servers automatically collect limited amounts of standard information for traffic monitoring and statistical purposes (e.g. browser version, pages visited, dates and times of access, etc.). The information is analyzed for operational trends, performance, ways to improve our site, and for the day-to-day administration of Reactome. None of this information is analyzed in a personally identifiable manner.

Personal information is any information about an identifiable individual. When we collect personal information about you through the website, we do so only if you consent and provide it to us. Specifically, there are four ways we may collect and use personal information about you:

  1. if you agree to act as a reviewer or author of a Reactome pathway, we collect your reviewer or author information (e.g. name, ORCID ID, email address and institutional affiliation) for the purpose of credit attribution on the published pathway;  
  1. if you contact the Reactome help desk, we collect your name, email address and information related to your request, question or concern for the purposes of responding and, if applicable, troubleshooting;
  1. if you provide your email address when using the Reactome GSA analysis service, we use it to notify you when your analysis is complete; and/or
  1. if you register to join our mailing list, we collect your email address in order to send you our publications and information about events.

Who will have access to your personal information?

Please note that authorized staff may be located outside Canada, including in the United States and Europe, and therefore, your personal information may become subject to the laws of those countries.

How long do we keep your personal information?

We will keep the personal information only as long as necessary for the fulfilment of the purposes for which it was collected and for which consent was received, unless otherwise authorized or required by law.
