Privacy
Privacy. What I collect and why.
This site collects as little as it can. Here is all of it.

Who runs this site
Tanvir Chowdhury runs tanvirchowdhury.com. For anything about your data, email tanvir@tanvirchowdhury.com.
What the site itself collects
The site uses Google Analytics to count visits and see which pages help, such as how many people click Book a call. It sets Analytics cookies only if you click Allow on the cookie notice; until then, Google receives only cookieless signals (the page, browser and approximate location), with no cookie and nothing stored on your device. There is no ad tracking. You can change your choice any time with Cookie settings at the bottom of each page. Its fonts are served from this site, not from Google. The host, Vercel, keeps standard server logs (IP address, browser and the pages requested) to run and protect the site.
Booking a call
The Book a call buttons open Calendly. When you book, Calendly collects your name, email address and any answers you give, under its own privacy policy. I use them to prepare for and hold our call.
Email and follow-up
If you email me or book a call, I keep your name, email address and our messages in my email (Google Workspace) and my contact list (HubSpot), so I can reply and follow up.
The newsletter
If you subscribe to Ask Tanvir, your email address is stored with my newsletter provider, beehiiv, to send you each issue. Every issue has an unsubscribe link.
What I don’t do
I don’t sell your data. I don’t share it with anyone except the services named on this page.
Your choices
Email tanvir@tanvirchowdhury.com to see, correct or delete what I hold about you, or to stop any follow-up.
