Privacy Policy

Last Updated: September 08, 2026

This Privacy Policy explains how AjaxCalculators.com handles information when you visit the website, use its calculators and tools, contact the website, or interact with its features.

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

Throughout this Privacy Policy, the terms “AjaxCalculators,” “we,” “us,” and “our” refer to AjaxCalculators.com and its Admin where appropriate.

Website Operator

AjaxCalculators is independently managed and maintained by its Admin.

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

The Admin is responsible for the website’s development, operation, technical maintenance, calculator implementation, testing, review, and privacy practices.

Our Privacy Approach

AjaxCalculators was created to help people solve everyday problems through practical online calculators.

We aim to collect and process only the information reasonably necessary to operate, secure, improve, and maintain the website.

We do not want users to provide unnecessary personal or sensitive information simply to use ordinary calculators.

Information You Provide Voluntarily

You may provide information directly to AjaxCalculators when you:

  • contact us by email;

  • submit a contact form;

  • report an incorrect calculator result;

  • report a technical problem;

  • suggest a calculator;

  • suggest a source or methodology;

  • send general feedback;

  • submit a privacy request; or

  • contact us for another legitimate reason.

Depending on what you submit, this information may include:

  • your name;

  • email address;

  • message content;

  • calculator URL;

  • technical details;

  • screenshots;

  • browser or device information that you provide; and

  • other information you voluntarily include in your message.

Please do not send personal information that is not necessary for your request.

Calculator Inputs

AjaxCalculators provides calculators that process values entered by users.

Where a calculator performs its calculations directly within the user’s browser, the values entered into that calculator are processed according to the technical implementation of the tool.

AjaxCalculators does not intentionally collect ordinary calculator inputs merely for the purpose of building personal profiles about users.

However, the exact technical behaviour may differ for certain tools or services if they rely on external functionality.

Where a calculator or feature requires external processing, users should be informed where appropriate.

AI-Assisted Development and User Data

Artificial intelligence may be used by the Admin as part of the website-development workflow.

AI may assist with:

  • writing or improving code;

  • debugging;

  • suggesting potential test cases;

  • organising technical research;

  • improving interfaces;

  • reviewing implementation possibilities;

  • drafting technical documentation; and

  • other development-related tasks.

The use of AI during development does not mean that ordinary calculator inputs are automatically sent to an AI provider.

Calculator development and calculator data processing are separate matters.

AjaxCalculators does not intentionally send ordinary calculator inputs to an AI service simply because AI-assisted tools were used when developing the calculator.

If a future website feature directly uses an AI or other external service to process user information, the relevant data handling should be disclosed where appropriate.

Automatically Collected Technical Information

Like most websites, AjaxCalculators may automatically receive or process certain technical information when users visit the website.

This may include:

  • IP address;

  • browser type;

  • operating system;

  • pages visited;

  • approximate geographic information;

  • date and time of access;

  • interaction data;

  • server logs;

  • error information;

  • cookie identifiers; and

  • other standard technical information.

This information may be processed for purposes such as:

  • keeping the website operational;

  • protecting the website from abuse;

  • identifying technical problems;

  • understanding website usage;

  • improving user experience;

  • improving calculators;

  • website analytics;

  • performance monitoring; and

AjaxCalculators may use analytics services such as Google Analytics or similar tools to understand how visitors use the website.

Analytics information may help us understand:

  • which pages are visited;

  • how users arrive at the website;

  • which device types are used;

  • general geographic usage;

  • engagement with website pages;

  • technical performance; and

  • overall website usage trends.

Analytics services may use cookies or similar technologies according to their own terms and privacy policies.

Where applicable, consent mechanisms may be used in accordance with legal requirements.

Cookies and Similar Technologies

AjaxCalculators may use cookies or similar technologies.

These may be used for purposes including:

  • essential website functionality;

  • consent management.

Some cookies may be set directly by AjaxCalculators, while others may be set by third-party services used by the website.

Users may be able to control or remove cookies through their browser settings.

Disabling certain cookies may affect how some website features operate.

Advertising

AjaxCalculators may display advertising provided by third-party advertising services.

Advertising providers may use cookies, identifiers, or similar technologies to:

  • deliver advertisements;

  • measure advertisement performance;

  • limit repeated advertisements;

Third-party advertising providers process information according to their own privacy policies and applicable legal requirements.

Where legally required, consent may be requested before certain advertising technologies are used.

Google Services

AjaxCalculators may use services provided by Google, such as:

  • Google Analytics;

  • Google Search-related services;

  • advertising services; or

  • other website measurement and management technologies.

Google may process information in accordance with its own privacy policies, terms, and service configurations.

Users should review Google’s privacy information if they want to understand how Google handles information across its services.

Contact Forms and Email

When you contact AjaxCalculators, information you provide may be used to:

  • respond to your inquiry;

  • investigate calculator errors;

  • reproduce technical problems;

  • evaluate suggested methodologies;

  • review source corrections;

  • respond to privacy requests;

Messages may be retained for a reasonable period where necessary to:

  • respond to the request;

  • maintain a record of technical reports;

  • investigate recurring issues;

Error Reports

When users report an incorrect calculator result, the Admin may use the information provided to reproduce and investigate the calculation.

This may include:

  • input values;

  • units;

  • displayed result;

  • expected result;

  • supporting formulas;

  • source links;

  • screenshots; and

  • technical details.

Users should avoid including unnecessary personal information when reporting calculator problems.

Hosting and Server Logs

AjaxCalculators is hosted using third-party hosting and infrastructure services.

Hosting providers may automatically process technical information required to:

  • deliver website content;

  • maintain server security;

  • detect malicious activity;

  • troubleshoot server problems;

  • maintain backups; and

  • operate hosting infrastructure.

Server logs may include information such as IP addresses, requested URLs, timestamps, browser information, and server-response information.

Security

AjaxCalculators uses reasonable measures intended to protect the website and information processed through it.

These measures may include:

  • HTTPS encryption;

  • hosting security;

  • software updates;

  • access controls;

  • security monitoring;

  • anti-spam measures;

  • backups; and

  • other appropriate technical protections.

However, no website, internet transmission, hosting platform, or electronic storage system can guarantee absolute security.

Users should therefore avoid sending unnecessary confidential or sensitive information through the website.

Information We Do Not Ask You to Send

Please do not send AjaxCalculators unnecessary sensitive information such as:

  • passwords;

  • authentication credentials;

  • banking passwords;

  • full payment-card information;

  • government identification documents;

  • confidential tax records;

  • private medical records;

  • authentication codes;

  • security questions and answers; or

  • other highly sensitive information.

If a screenshot is required to explain a technical issue, remove or hide unrelated personal information before sending it.

AjaxCalculators may contain links to:

  • source material;

  • government websites;

  • scientific organisations;

  • professional organisations;

  • documentation;

  • educational resources;

  • external services; or

  • other third-party websites.

This Privacy Policy does not govern third-party websites.

Each external website is responsible for its own privacy practices, cookies, security, and data processing.

Users should review the privacy policies of third-party services they choose to visit.

Embedded Content and External Services

Certain pages may include functionality, media, scripts, or resources provided by third parties.

Depending on the service, the third party may receive technical information such as:

  • IP address;

  • browser information;

  • device information;

Sale of Personal Information

AjaxCalculators does not operate as a business whose purpose is to sell users’ personal information.

Where applicable privacy laws define terms such as “sale” or “sharing” more broadly in relation to advertising technologies, users may have additional legal rights concerning those activities.

Data Retention

Information is kept only for as long as reasonably necessary for the purpose for which it was collected or as required for legitimate operational, security, legal, or compliance reasons.

Retention periods can differ depending on the type of information.

For example:

  • temporary technical logs may be retained for security or troubleshooting;

  • analytics information may follow the retention settings of the analytics service;

  • contact messages may be retained while an inquiry or technical report remains relevant; and
