Celo Foundation Brand Policy

These Rules apply to any licensee’s use of the Celo Foundation’s wordmarks, designmarks, and similar intellectual property (the “Brand Assets”). By using or reproducing a Brand Asset each licensee (hereinafter referred to individually as “you”) is agreeing to abide by this policy that forms a binding agreement between you and the Celo Foundation (the “Foundation”). If you are using a Brand Asset on behalf of a legal entity such as your employer, you represent that you have the authority to bind such entity, and the terms “you” or “your” shall include such entity. If you do not agree to these Rules, you are not authorized to use the Brand Assets. This policy may be updated by the Foundation at its discretion from time to time.
This policy is intended to promote consistent use of the Brand Assets for the larger community. This makes it easier for people to instantly recognize references to Celo, a decentralized technology, and related products, and prevents market confusion. This policy is also intended to protect the Brand Assets. In following this policy, you help the Celo community protect valuable trademark rights from dilution and disparagement, while strengthening the Celo technology brand identity.

Ownership of Brand Assets

You acknowledge that the Foundation is the sole and exclusive owner of Celo related trademarks, brand assets, and derivatives thereof. You promise that you will not interfere with the Foundation’s rights in the Brand Assets, including by challenging the Foundation’s use, registration, or application to register any Brand Asset or by registering any Brand Asset (including any derivative form, and foreign translation or transliteration thereof) yourself anywhere in the world.

Social Media Guidelines

In addition to the Trademark Guidelines above, the name and handle of your social media account and any and all pages should not begin with a Celo related trademark. In addition, Celo logos cannot be used in a way that might suggest affiliation with the Celo Foundation, including, but not limited to, the account, profile, or header images. The only exception to these requirements is if you’ve received prior permission from the Celo Foundation.
For example, you cannot name your account, page, or community “Celo Representatives” or “Celo Software.” However, it would be acceptable to name your account, page, or community “Fans of Celo” or “Information about Celo Platform” as long as you do not use the Celo logos or otherwise suggest any affiliation with the Celo Foundation.
