F4 uses administrative, technical, and organizational safeguards intended to protect personal information and Customer Materials against unauthorized access, loss, misuse, alteration, or disclosure.

No system or transmission method is completely secure. Customers are responsible for protecting their credentials, devices, authorized-user access, and downloaded Deliverables.

If F4 confirms a security incident involving personal information, F4 will provide notices required by applicable law and any separately signed agreement.

#8. Retention and Deletion

Final Deliverables are ordinarily available for six calendar months after the final Deliverables become available. The platform may display the exact expiration date.
