Privacy Policy

Effective date: September 25, 2026

Taptwice Media (“we,” “us,” or “our”) operates Hierarchical Navigable Small World at hierarchicalnavigablesmallworld.com (the “Site”). This Privacy Policy explains what information we collect when you visit the Site, how we use it, and the choices you have.

Who we are

The Site is an educational documentation project about Hierarchical Navigable Small World (HNSW) indexing and related approximate nearest-neighbor topics. It is published by Taptwice Media. For privacy questions, contact us at markshubh@gmail.com.

Information we collect

Information you provide

We do not require an account to read the documentation. If you email us, we receive whatever you include in that message (typically your email address and the content of your inquiry). We use that information only to respond.

Information collected automatically

Like most websites, our hosting environment and WordPress may process standard technical data when you visit, such as IP address, browser type, requested URLs, and timestamps in server logs. We use this for security, abuse prevention, and keeping the Site available.

Cookies and similar technologies

WordPress may set essential cookies when you are a logged-in administrator or when other core features require them. We do not currently run third-party advertising cookies or a marketing pixel on the Site. See our Cookie Policy for details.

How we use information

We use the information described above to:

• Operate, maintain, and secure the Site
• Respond to messages you send us
• Diagnose technical issues and prevent abuse
• Comply with legal obligations when required

We do not sell your personal information.

Sharing of information

We may share limited information with service providers who help us run the Site (for example, web hosting and backup). Those providers process data on our behalf under their own security and privacy practices. We may also disclose information if required by law, or to protect the rights, safety, and integrity of the Site and its users.

Retention

Server logs are retained according to our hosting provider’s defaults and operational needs. Email correspondence is kept only as long as needed to handle your request and any follow-up. Backup copies may persist for a limited recovery window.

International visitors

The Site may be hosted or accessed from locations outside your country. If you visit from the European Economic Area, United Kingdom, or a similar jurisdiction, the legal bases for processing typically include legitimate interests in operating a public documentation site and security, and performance of a request when you contact us.

Your rights

Depending on where you live, you may have rights to access, correct, delete, or restrict processing of personal data we hold about you, or to object to certain processing. To exercise these rights, email markshubh@gmail.com. We may need to verify your request before acting on it.

Children

The Site is not directed at children under 16, and we do not knowingly collect personal information from them.

Changes

We may update this Privacy Policy from time to time. The effective date at the top of this page will change when we do. Continued use of the Site after an update means you accept the revised policy.
