Terms and Conditions

Last Updated: September 08, 2026

These Terms and Conditions govern your use of AjaxCalculators.com, including its calculators, converters, content, and related website features.

By using AjaxCalculators, you agree to these Terms. If you do not agree, please discontinue use of the website.

AjaxCalculators.com is independently owned and operated by Arefin Bappy, who serves as the website’s Owner and Admin.

1. Purpose of AjaxCalculators

AjaxCalculators was created to help people solve everyday problems through practical online calculators and related informational resources.

The website includes tools covering areas such as mathematics, finance, science, health and fitness, construction, measurements, conversions, education, and other practical calculations.

The calculators and supporting information are provided primarily for general informational, educational, and decision-support purposes.

2. Ownership and Administration

AjaxCalculators is independently managed, developed, tested, reviewed, and maintained by its Admin.

Owner & Admin: Arefin Bappy
Website: AjaxCalculators.com
Contact: support@ajaxcalculators.com

The Admin is responsible for the website’s development, calculator implementation, review, maintenance, and administration.

3. Calculator Development, Testing, and AI Assistance

AjaxCalculators aims to build calculators using an established, widely accepted, or otherwise appropriate method for the intended calculation.

Depending on the subject, this may include mathematical formulas, scientific equations, conversion relationships, financial formulas, statistical methods, recognised estimation methods, reference values, published guidelines, or technical standards.

Where multiple recognised methods exist and the difference may materially affect the result, the relevant calculator may explain which method is used.

Calculators are individually tested and reviewed. Testing may include manual calculations, known examples, different input values, unit conversions, validation, edge cases, rounding, and desktop or mobile functionality.

Artificial intelligence may assist the Admin with coding, debugging, research organisation, test-case suggestions, documentation, and other development tasks. AI-generated output is not automatically considered accurate. The Admin remains responsible for reviewing, testing, modifying, and deciding what is published.

10. No Professional Relationship

Using AjaxCalculators does not create a medical, financial, legal, engineering, accounting, tax, or other regulated professional relationship.

The Admin is a professional web developer responsible for the technical development and review of the website. He does not claim regulated professional qualifications through AjaxCalculators unless specifically stated.

Health, financial, construction, technical, and other high-impact calculator results should not replace qualified professional guidance where such guidance is required.
