One inbox, read by the owner

Every message to this website lands in one inbox, and I read it myself. My name is Talha Kayani. I own and develop ti-84calculator.com, and I answer reader email personally rather than through a support team.

Email: contact@ti-84calculator.com

What to write to us about

• A wrong result. Tell me the tool name and the values you entered. I test the tool again by hand, and I fix a real error on the page itself.
• A tool request. Tell me the calculation you needed and could not find in a working form. Reader requests shaped this site from the start, and a good request joins the build list.
• A question about an article. Salma Tahira reviews our content, and a question about wording or a source goes to her through the same inbox.
• Business inquiries. SEO, content, and social media services run through my company, Trivexa Digital. A short email with your goal is enough to start that conversation.

Response time

I reply to most messages within two working days. A correction report about a tool result gets priority and usually receives a reply first.

What not to send

Never send a password, a bank detail, an ID card number, or any private document to this inbox. The tools on this site need no personal data, and neither does an email to us. Our Privacy Policy explains how this site handles data, in full.
