7. California Privacy Rights

California residents may have certain rights concerning their personal information under applicable California privacy laws. Depending on the law’s applicability and available exemptions, these may include rights to request access to, correction of, or deletion of certain personal information and to obtain information regarding how personal information is collected, used, or disclosed.

Certain uses of cookies, pixels, and advertising technologies may constitute “sharing” or other regulated processing under applicable California privacy law even when no money is exchanged. Where applicable, COSF will provide appropriate mechanisms to exercise legally required opt-out rights.

COSF will not discriminate against an individual for exercising an applicable privacy right.

Requests concerning privacy rights may be submitted using the contact information below. We may need to verify your identity before fulfilling certain requests.

8. International Visitors

COSF welcomes supporters from around the world. Personal information may be transferred to and processed in the United States and other jurisdictions where COSF’s service providers operate.

For individuals in the European Economic Area or United Kingdom, where applicable, COSF’s bases for processing may include consent, performance of a transaction or agreement, compliance with legal obligations, and COSF’s legitimate interests.

Where applicable, individuals may have rights to access, correct, delete, restrict, or object to certain processing of their personal information, withdraw consent, and lodge a complaint with an appropriate data protection authority.

9. Data Retention

We retain personal information for as long as reasonably necessary for the purposes for which it was collected, including maintaining donation, tax, accounting, event, organizational, and legal records and resolving disputes.

Retention periods may vary depending on the type of information and applicable legal requirements.

10. Data Security

COSF maintains reasonable administrative, technical, and physical safeguards designed to protect personal information. However, no website, electronic transmission, or storage system can be guaranteed to be completely secure.

11. Children’s Privacy

Our general website is not directed to children under 13, and we do not knowingly collect personal information online from children under 13 through the general website without appropriate authorization.

Because COSF’s charitable mission relates to pediatric oncology, information relating to children or families may be collected in connection with particular programs, grants, stories, events, or initiatives. Where appropriate, COSF will seek authorization or consent from a parent, guardian, or other authorized individual before collecting or publicly using a child’s personal information.

12. Communications and Marketing Choices

You may unsubscribe from COSF marketing emails at any time by using the unsubscribe link included in the communication.

You may also contact COSF regarding your communication preferences or privacy rights.

Opting out of marketing communications does not prevent COSF from sending transactional or administrative communications relating to donations, registrations, transactions, or other interactions with COSF.

13. Third-Party Websites

Our website may contain links to third-party websites, social networks, payment processors, event platforms, or other services. COSF is not responsible for the privacy practices of third parties, and we encourage visitors to review the privacy policies of those services.
