You have a meaningful ability to limit how Nintendo and its advertising partners use your data to serve you personalized ads, but you may need to take active steps to exercise this right.
Nintendo collects extensive personal data including gameplay habits, purchase history, device identifiers, and communications, and may share this with third-party advertising and analytics partners. Children under 13 receive additional protections through parental consent requirements under COPPA, and California residents have rights to access, correct, delete, or opt out of the sale or sharing of their personal information. You can submit a privacy rights request through Nintendo's dedicated privacy request portal at https://www.nintendo.com/us/privacy-policy/.
