By donating to the White Heart Foundation you agree to these terms: The White Heart Foundation reserves the right for its discretion and control over all contributions. The White Heart Foundation may endeavor to honor donors' wishes that designate the use of donated funds. White Heart, though, must legally maintain control over the ultimate determination of how all donated funds are allocated. Please be aware that, although White Heart will make every effort to honor the donors' contribution designation, contributions become the property of White Heart, and White Heart has the discretion to determine how best to use all contributions to carry out it's functions and purposes.
