Privacy Policy

What we collect

When you visit bigintbd.com, we record a rough, anonymous visit count for each page — nothing more. We generate a one-way cryptographic hash from your IP address and browser's user-agent string purely to avoid counting the same visit twice within a short window. That hash cannot be reversed back into your IP address or used to identify you, and we do not store your raw IP address, use tracking cookies, or link visits across sessions. Visit records are automatically deleted after 90 days.

Contact form submissions

If you submit our contact form, we store the information you provide — your name, email address, and message, plus any optional fields you fill in — so we can respond to your inquiry. We also record your IP address and browser user-agent with that submission for spam prevention. We send a copy of your message to our team's email inbox. We do not sell or share this information with third parties, and we do not use it for marketing without your separate consent.

Cookies and local storage

We use your browser's local storage (not cookies) to remember your dark/light theme preference. This stays on your device and is never transmitted to our servers.

Third-party services

We use standard web infrastructure (hosting, email delivery) to operate this site. These providers process data only as needed to deliver their service to us and are bound by their own privacy commitments.

Your rights

You can ask us what information we hold about you, request a correction, or request deletion, by emailing info@bigintbd.com. We'll respond within a reasonable time.

Changes to this policy

If we materially change how we handle your information, we'll update this page and revise the date above.
