Bug Bounty Program

Our Bug Bounty Program allows us to recognize and reward members of the community for helping us find and address significant bugs, in accordance with the terms of the Bug Bounty Program set out below.

Although our team of experts has made every effort to squash all the bugs in our systems, there's always the chance that we might have missed one posing a significant vulnerability. If you discover a bug, we appreciate your cooperation in responsibly investigating and reporting it to us so that we can address it as soon as possible. For significant bugs we offer reward and recognition.


If you comply with the policies below when reporting a security issue, we will not initiate a lawsuit or law enforcement investigation against you in response to your report. We ask that:

  • You give us reasonable time to investigate and mitigate an issue that you report before making any information about the report public or sharing such information with others.
  • You do not exploit a security issue that you discover for any reason.
  • You do not interact with an individual account (which includes modifying or accessing data from the account) if the account owner has not consented to such actions.
  • You do not intentionally violate any other applicable laws or regulations, including (but not limited to) laws and regulations prohibiting the unauthorised access to data.
  • You make a good faith effort to avoid privacy violations and disruptions to others, including (but not limited to) unauthorised access to or destruction of data, and interruption or degradation of our services.
  • For the purposes of this policy, you are not authorised to access user data or company data, including (but not limited to) personally identifiable information and data relating to an identified or identifiable natural person.
