4. Legal Basis for Processing

For visitors and clients located in jurisdictions that require a legal basis for processing personal data, we rely on the following grounds. Consent is used when you voluntarily provide information through our contact forms or subscribe to communications. Contractual necessity applies when processing is required to deliver the services you have requested or to take steps at your request before entering into a service agreement. Legitimate interests cover our use of data for website analytics, security monitoring, and business development, provided these interests are not overridden by your data protection rights. Legal obligation applies when we must process data to comply with applicable laws and regulations.

5. Data Sharing and Disclosure

We do not sell, rent, or trade your personal information to third parties for their marketing purposes. We may share your information only in the following limited circumstances.

5.1 Service Providers

We may engage trusted third-party companies and individuals to perform functions on our behalf, such as website hosting, email delivery, analytics, and customer relationship management. These service providers have access to personal information only as necessary to perform their functions and are contractually obligated to maintain the confidentiality and security of your data. They are not permitted to use your information for any purpose other than providing services to NiuLogic Solutions LLC.

5.2 Legal Requirements

We may disclose your information if required to do so by law or in response to valid legal requests by public authorities, including courts, law enforcement agencies, or regulatory bodies. We may also disclose information when we believe in good faith that disclosure is necessary to protect our rights, protect your safety or the safety of others, investigate fraud, or respond to a government request.

5.3 Business Transfers

In the event that NiuLogic Solutions LLC is involved in a merger, acquisition, reorganization, or sale of all or a portion of its assets, your information may be transferred as part of that transaction. We will provide notice before your personal information is transferred and becomes subject to a different privacy policy.

5.4 Aggregated and De-Identified Data

We may share aggregated, anonymized, or de-identified information that cannot reasonably be used to identify you with third parties for industry analysis, research, or other legitimate business purposes.

6. Data Retention

We retain personal information only for as long as necessary to fulfill the purposes described in this Privacy Policy, unless a longer retention period is required or permitted by law. The criteria used to determine our retention periods include the length of time we have an ongoing relationship with you, whether there is a legal obligation to which we are subject, and whether retention is advisable in light of our legal position regarding statutes of limitations, litigation, or regulatory investigations. When personal information is no longer needed, we securely delete or anonymize it in accordance with our data disposal procedures.

7. Data Security

NiuLogic Solutions LLC implements appropriate technical and organizational measures to protect your personal information against unauthorized access, alteration, disclosure, or destruction. These measures include encryption of data in transit and at rest, secure server infrastructure, access controls and authentication mechanisms, regular security assessments and vulnerability testing, employee training on data protection practices, and incident response procedures. While we strive to use commercially acceptable means to protect your personal information, no method of transmission over the Internet or electronic storage is one hundred percent secure. We cannot guarantee absolute security, but we continuously monitor and improve our security posture.
