Privacy Policy

CalculatorX is built around a simple idea: calculate in your browser, keep your inputs private by default.

Calculations

Interactive calculators and converters are designed to run locally on your device. We do not require an account, and we do not need your numbers to leave your browser in order for a tool to produce a result.

Shared URLs and remote REST/MCP calculations

Opening a shared calculation URL sends its URL parameters to our hosting service so that the result can be rendered before JavaScript runs. URLs can also remain in browser history and in hosting or intermediary access logs. A shared URL is not a private storage channel.

REST and MCP are remote services. When you call them, CalculatorX receives the calculation inputs and request metadata needed to process the request and return the result. Browser-local calculation does not mean that REST/MCP requests stay on your device. Your MCP client or AI provider may also process the request under its own privacy policy.

The service is hosted on Cloudflare. Hosting, security and analytics services may process request metadata, such as IP addresses, timestamps, requested URLs and response status, under their configurations and policies. This policy does not promise zero logging, a fixed log retention period or processing in a particular country. It does not establish a guaranteed deletion time for hosting logs; contact us through the site's Contact page for questions about a specific request. Do not send confidential or personal information in calculation inputs or shared URLs.

Analytics and advertising

To understand traffic and keep the site free, we may use standard web analytics and advertising partners (for example Microsoft Clarity and, when configured, Google Analytics / AdSense). Those services may set cookies or similar technologies and process usage data under their own policies.

What we do not do

• We do not sell your personal information.
• We do not ask you to create an account to use core tools.
• We do not use your calculator inputs as a product dataset.

Contact

If you email us, we use your message only to respond to that inquiry.

Changes

We may update this policy as the site evolves. The version on this page is the current one.
