We strive for transparency in our operations and finances to be accountable to our stakeholders and the public. A full description of this rationale is in our Partnership Framework.

We ask for your help in honoring this commitment to transparency. If you decide to donate to COS we request that you also allow us to publicly recognize you for your generosity. We will list you as a donor on our website and in our annual reporting documents but will not list your donation amount. If you prefer to remain anonymous, we encourage you to take advantage of another way of donating. You can give anonymously to COS via PayPal Giving Fund, Network for Good, or major donor-advised funds. This way, you will remain anonymous to both COS and the public, and your donation will still have the full impact you intend.

Please contact the COS Development Team with any questions at giving@cos.io or at (434) 207-2133.
