The Services are not directed to, nor do we knowingly collect information from, children under the age of 18.

If you become aware that your child or any child under your care has provided us with information without your consent, please contact us at the contact information listed below. If we learn that we have collected personal information directly from children through our Sites without being permitted to do so by applicable law, we will delete this information


Unless indicated otherwise in this Privacy Notice, the criteria we use to decide how long we retain personal information include: (i) whether we need your personal information to perform a contract to which you are subject, to respond to your questions or provide to you with the required service or support, (ii) whether there is a legal obligation to which we are subject, or (iii) whether retention is advisable in light of our legal position (such as in regard to applicable statutes of limitations, litigation, or regulatory investigations).

We delete personal information when it is no longer necessary to retain it for the purposes described in this Privacy Notice, or when required to do so by applicable law.


We strive to have administrative, technical, and physical safeguards designed to protect the information collected by the Services. However, no information system can be 100% secure, so we cannot guarantee the absolute security of your information. Moreover, we are not responsible for the security of information you transmit to the Services over networks that we do not control, including the Internet and wireless networks.


Information collected through the Services will be processed in and subject to the laws of the United States, which, if you are not located in the United States, may not provide the same level of protection for your personal information as your home country, and may be available to the United States government or its agencies under a lawful order made in the United States. In addition, we may transfer your information outside the United States to our affiliates, business partners, and service providers located in other countries.

We have put in place appropriate safeguards (such as contractual commitments) in accordance with applicable legal requirements to provide adequate protections for your personal information. For example, if you are located in the European Economic Area (EEA), the United Kingdom (UK) or Switzerland and your personal information are transferred to Sellas, meaning in United States, or to Sella’s third-parties in other countries which have different standards of data protection to the EEA, UK and Switzerland, such transfers are governed by Standard Contractual Clauses, where appropriate, or other legally recognized measures that adequately protect the personal information.

For more information on the appropriate safeguards in place, and to obtain a copy of such safeguards, please contact us at the contact information set forth below.


If you have questions or concerns regarding the way in which your personal information has been used, please contact us at .

We are committed to working with you to obtain a fair resolution of any complaint or concern about privacy. If, however, you believe that we have not been able to assist with your complaint or concern, you may have the right to make a complaint to the data protection authority of your country of residence.


We may update this Privacy Notice from time to time. If we update this Notice, we will notify you by posting a new Privacy Notice on this page. If we make any changes that materially change the ways we process or protect your information, we will provide additional notification of the changes. When we update this Privacy Notice, we will indicate when it was most recently updated by changing the “last updated” date. Unless otherwise indicated, updates to this Privacy Notice are effective immediately upon posting.
