Privacy Policy

Introduction

Welcome to RanjanKumar.in. This Privacy Policy explains how we collect, use, and protect your personal information when you visit our website.

Information We Collect

Automatically Collected Information

When you visit our website, we may automatically collect certain information about your device, including:

• Browser type and version
• Operating system
• IP address
• Pages visited and time spent on pages
• Referral source

Newsletter Subscriptions

If you subscribe to the newsletter, we store your email address, the page you subscribed from, and the dates you subscribed, confirmed, and (if applicable) unsubscribed. Nothing else about you is stored, and the address is never sold, rented, or shared with anyone.

Subscription is double opt-in: an address receives nothing until you click the confirmation link we email you. The list is used only to notify subscribers when a new article is published. Every email carries a one-click unsubscribe link, and unsubscribing takes effect immediately. To have your record deleted outright rather than marked unsubscribed, just ask.

The list is stored in a database on our own server. Emails are delivered through Resend, which processes your address solely to deliver those messages. We do not track opens or clicks.

Cookies and Analytics

We use Google Analytics 4 to see which pages are read. It runs in Google Consent Mode: until you accept analytics in the cookie banner, it sets no cookies and sends Google only cookieless measurements (such as the page viewed, with no identifier that persists across visits). If you accept, it sets these cookies:

• _ga and _ga_<id> - distinguish visitors and sessions; expire after 2 years

One strictly necessary cookie, cc_cookie, remembers your cookie choice for 6 months. It is set on .ranjankumar.in, so one choice applies to this website, mermaid.ranjankumar.in and the book sites alike. No cookies are used for advertising.

You can change or withdraw your choice at any time from Cookie settings in the site footer. Withdrawing consent deletes the Google Analytics cookies. Google's handling of this data is described in the Google Privacy Policy.

The book sites linked from this website (7genai.ranjankumar.in, langgraph.ranjankumar.in, chatml.ranjankumar.in and chattemplates.ranjankumar.in) use the same Google Analytics setup, the same cookie banner and the same shared choice, and are covered by this policy. Each has its own Cookie settings link in its footer. Their fonts and scripts are served from ranjankumar.in's own server.
