Addendum for European Users

This Addendum for European Users supplements our Privacy Policy and applies to users of our Site who are located in the EEA or the U.K. (“European Users”). For European Users, “personal information,” as used in the Privacy Policy, means any information relating to an identified or identifiable individual.


If you are located in the EEA or the U.K., we only process your personal information when we have a valid “legal basis”, including when:

  • Consent. You have consented to the use of your personal information, for example to use cookies.
  • Contractual necessity. We need your information to provide you with the Site, for example to respond to your inquiries.
  • Compliance with a legal obligation. We have a legal obligation to use your personal information, for example to comply with tax and accounting obligations.
  • Legitimate interests. We or a third party have a legitimate interest in using your personal information. In particular, we have a legitimate interest in using your personal information for product development and internal analytics purposes, and otherwise to improve the safety, security, and performance of our Site. We only rely on our or a third party’s legitimate interests to process your personal information when these interests are not overridden by your rights and interests.


European Users have the additional rights described below.

  • You may request access to the personal information we maintain about you, update and correct inaccuracies in your personal information, restrict or object to the processing of your personal information, have the personal information anonymized or deleted, as appropriate, or exercise your right to data portability to easily transfer your personal information to another company.  In addition, you have the right to lodge a complaint with a supervisory authority, including in your country of residence, place of work or where an incident took place.
  • You may withdraw any consent you previously provided to us regarding the processing of your personal information, at any time and free of charge. We will apply your preferences going forward and this will not affect the lawfulness of the processing before you withdrew your consent.

You may exercise these rights by contacting us using the contact details at the end of the Privacy Policy. Before meeting your request, we may ask you to provide reasonable information to verify your identity. Please note that there are exceptions and limitations to each of these rights, and that while any changes you make will be reflected in active user databases instantly or within a reasonable period of time, we may retain information for backups, archiving, prevention of fraud and abuse, analytics, satisfaction of legal obligations, or where we otherwise reasonably believe that we have a legitimate reason to do so.


We take measures to delete your personal information or keep it in a form that does not permit identifying you when this personal information is no longer necessary for the purposes for which we process it, unless we are required by law to keep this personal information for a longer period. When determining the specific retention period, we take into account various criteria, such as the type of service provided to you, the nature and length of our relationship with you, and mandatory retention periods provided by law and the statute of limitations.
