Terms and conditions

Last updated: October 28, 2026

Acceptance of these terms

Use of ti-84calculator.com means acceptance of these terms. A visitor who disagrees with a term should stop using the site. Talha Kayani owns and operates this website, and these terms form the agreement between the visitor and the owner.

The service

This website provides free online calculators, converters, estimators, and written guides. The tools run in the visitor's browser. The site requires no account and charges no fee for its tools or articles.

Personal use

A visitor may use every tool for personal, educational, and professional day-to-day purposes at no cost. A teacher may use the tools in a classroom. A student may use the tools for study and assignments. A professional may use the tools inside ordinary work, such as an estimate for a client, with the accuracy limits in the Disclaimer in mind.

Limits on use

A visitor must not:

  • Copy the tools, page text, charts, or infographics from this site for republication on another website
  • Scrape the site at a volume that burdens the server or other visitors
  • Attempt to break, probe, or bypass the security of the site
  • Present a result from a tool on this site as an official figure from a government body, a board, a bank, or any other authority
  • Use the site or its results for an unlawful purpose

Ownership of content

The text, tool designs, charts, and infographics on this site belong to Talha Kayani unless a page credits another source. Short quotations with a clear credit line and a link back to the page are welcome. Full-page copying is not permitted.

Accuracy

The tools produce results from the formulas and rates stated on their pages. The owner tests every tool before publication and corrects reported errors. Even so, the site provides results for information and estimation, and the Disclaimer sets the limits that apply. Official sources decide official matters.

Advertising

This website displays ads through Google AdSense to keep the tools free. An ad on this site belongs to its advertiser. The presence of an ad never counts as an endorsement from the owner, and the owner's tools never change a result because of an advertiser.

Availability

The site aims for continuous availability. Maintenance, hosting faults, and events outside the owner's control can interrupt access. The owner owes no compensation for an interruption.

Changes to these terms

A change to these terms appears on this page with a new date at the top. Continued use of the site after a change means acceptance of the new terms.

Governing law

The laws of Pakistan govern these terms, and the courts of Multan, Punjab hold jurisdiction over a dispute that the parties cannot settle by email first.
