Nintendo says it uses reasonable security measures to protect your data but explicitly states it cannot guarantee your information will never be accessed without authorization.
This analysis describes what Nintendo's agreement states, permits, or reserves. It does not constitute a legal determination about enforceability. Regulatory applicability and practical outcomes may vary by jurisdiction, enforcement context, and individual circumstances. Read our methodology
Nintendo's qualified security assurance means that in the event of a data breach, the company's contractual exposure may be limited by this disclaimer, and users should understand that no absolute security guarantee is made for payment card data, account credentials, or gameplay records.
Nintendo now explicitly discloses that it collects persistent identifiers (IP addresses, device IDs) from child users for operational, security, fraud prevention, and service improvement purposes, and states that contractual restrictions limit how service providers can use this data. Parents gain enhanced transparency by being able to view a named list of third-party games and applications authorized to access their child's account, rather than just managing access through settings. The policy also clarifies that location information may be used for check-ins at Nintendo locations and events in addition to location-based games. You can review and manage which third-party apps have access to your child's account through your Nintendo Account profile settings.
View change record →Nintendo now discloses that it uses location data not only for location-based games and friend connections, but also to enable check-ins at specific events and Nintendo locations, which is a new explicit use case. The policy now details how child user data including persistent identifiers like IP addresses and device IDs are collected and retained, with commitments to delete or de-identify data based on sensitivity and account activity. Parents can now see which third-party apps have been authorized to access their child's account before deciding whether to allow continued access, giving more visibility into connected applications.
View change record →The revised policy simplifies how Nintendo describes data retention, now stating information is retained only as long as reasonably necessary in accordance with applicable law, without prior detail about sensitivity-based retention practices. For child users, the policy no longer explicitly lists persistent identifiers (IP addresses, device identifiers) that Nintendo and service providers collect, removing specific disclosure language that previously detailed collection purposes for child accounts. The policy now indicates it collects error information from both users and devices, broadening the prior language focused on device errors only. The privacy certification body changed from CARU to ESRB, meaning independent audits and enforcement are now administered by the Entertainment Software Rating Board rather than the Children's Advertising Review Unit.
View change record →While Nintendo states it uses reasonable security measures, the policy's disclaimer that no transmission is completely secure means your personal and payment data carries inherent risk of unauthorized access, and Nintendo does not guarantee its protection.

"We use reasonable administrative, technical, and physical safeguards to protect your personal information from unauthorized access, use, and disclosure. However, no method of transmission over the Internet or electronic storage is completely secure, and we cannot guarantee the security of your information.— Excerpt from Nintendo's Nintendo Privacy Policy
REGULATORY LANDSCAPE: Security disclaimers of this type are standard in the industry but do not eliminate regulatory obligations under state data breach notification laws (all 50 US states have enacted such laws), FTC Act Section 5 (requiring reasonable security as an unfair practice standard), PCI DSS for payment card data, and GDPR Article 32 (requiring appropriate technical and organizational measures). The FTC has brought enforcement actions against companies whose security measures were found inadequate regardless of policy disclaimers. GOVERNANCE EXPOSURE: Low to Medium. The disclaimer is standard boilerplate but does not insulate Nintendo from regulatory scrutiny if a breach occurs and security measures are found inadequate. The breadth of data Nintendo holds (payment cards, account credentials, gameplay history across millions of users) makes the security posture particularly material. JURISDICTION FLAGS: All 50 US states require breach notification to affected consumers and state regulators, with varying timelines and thresholds. California, New York (SHIELD Act), and Illinois impose more specific security requirements and shorter notification windows. GDPR requires notification to supervisory authorities within 72 hours of discovering a breach affecting EU users. CONTRACT AND VENDOR IMPLICATIONS: Security obligations should flow down to all vendors and service providers with access to Nintendo customer data, including payment processors, cloud hosting providers, and analytics partners. Vendor contracts should specify minimum security standards, breach notification obligations, and audit rights. PCI DSS compliance should be verified for all parties in the payment data chain. COMPLIANCE CONSIDERATIONS: Legal teams should verify that Nintendo's incident response plan addresses all applicable state and international breach notification timelines. An independent assessment of technical and organizational security measures against the FTC's reasonable security standard and GDPR Article 32 requirements is advisable. The policy should be reviewed to confirm that security disclosures accurately reflect the current security posture.
