NDLSK only uses this information for the purpose for which you provided it, such as responding to a message, improving a tool, or providing requested information.

3. Cookies and similar technologies

This website may use cookies or similar technologies to support basic website functionality, analytics, performance measurement, security, or embedded third-party content.

Cookies are small files stored on your device by your browser. You can control or disable cookies through your browser settings.

Please note that disabling cookies may affect some website features.

4. Analytics

NDLSK may use privacy-conscious analytics or standard web analytics tools to understand general website usage, such as page views, traffic sources, device types, and visitor interactions.

Analytics data is used in aggregated or technical form to improve the website. It is not used to personally identify visitors unless required for security or legal reasons.

If third-party analytics services are used, those providers may process data according to their own privacy policies.

5. Third-party services and external links

NDLSK may link to or embed content from third-party websites and services, including but not limited to:

• documentation websites;
• external tools;
• social platforms;
• video or media platforms;
• analytics providers;
• hosting, deployment, or infrastructure services;
• payment or booking services, if added in the future.

NDLSK is not responsible for the privacy practices, content, security, or policies of third-party websites. When you follow an external link, you should review the privacy policy of that website or service.

6. Data sharing

NDLSK does not sell, rent, or trade personal information.

Information may be shared only when necessary with:

• service providers that help operate, host, secure, or analyze the website;
• legal, regulatory, or government authorities, if required by law;
• security providers, if needed to prevent abuse, spam, attacks, or fraud.

Any third-party service providers are expected to process information only as necessary to provide their services.

7. Data retention

NDLSK keeps personal information only for as long as reasonably necessary for the purposes described in this Privacy Policy, unless a longer retention period is required by law.

Technical logs, analytics data, and messages may be retained for different periods depending on operational, security, or legal needs.

8. Data security

Reasonable technical and organizational measures are used to protect information from unauthorized access, misuse, loss, or disclosure.

However, no website, server, network, or online transmission is completely secure. NDLSK cannot guarantee absolute security of information transmitted through the internet.

9. International visitors

NDLSK may be accessed from different countries. Depending on your location, your information may be processed in countries other than your own.

By using this website, you understand that information may be processed according to the laws and technical infrastructure applicable to the website owner, hosting providers, and service providers.
