Last modified: November 8, 2022
Cesium is located at 400 Market Street, Suite 1100, Philadelphia, PA 19106.
Why are you reading this?
By using Cesium ion, the “Service”, you agree to these Terms of Service and their modifications, hereafter known as the “Terms”. They apply whether you are contributing or receiving content on Cesium ion. It is important that you understand these Terms because they govern what you can and can’t do with the Service, what your rights and liabilities are, and what Cesium’s rights and liabilities are. This agreement represents a legal contract between you and Cesium.
Cesium will revise these Terms from time to time. Please check back on this page often to ensure you are aware of any changes or updates to the Terms. If you do not agree with these Terms or any of their revisions, you must stop using Cesium ion. Your use of the Service following any amendment of these terms of service will signify your assent to and acceptance of its revised terms.
- You must sign up for a user account in order to use most Services.
- If you live in a country in the European Region, you must be at least 16 years old to use our Services or such greater age required in your country to register for or use our Services. If you live in any other country except those in the European Region, you must be at least 13 years old to use our Services or such greater age required in your country to register for or use our Services. In addition to being of the minimum required age to use our Services under applicable law, if you are not old enough to have authority to agree to our Terms in your country, your parent or guardian must agree to our Terms on your behalf.
- You must be human. No “bots” or automated registration devices are permitted to create an account.
- You are only allowed to sign up for one account, and you are the only person authorized to log into that account.
- If you enter into this Agreement on behalf of a company or legal entity, you must have the authority to bind that entity to these Terms. In that case, “you” refers to the entity. Please note, if you are a government entity, there are special terms that apply (see “U.S. Government End User Rights” below).
- You are responsible for anything that occurs on your account, whether or not you authorized it. Cesium is not responsible for any harm that may result from your use of Cesium ion, nor will Cesium be liable for any losses or damages caused by unauthorized use. However, you may be liable for the losses that Cesium or others incur due to your use of the Service or by unauthorized use of your account. If you become aware of unauthorized use, you must notify Cesium immediately and cooperate with Cesium to respond to the security breach.
