Privacy Policy

Privacy overview

Online Calculator Tools is designed to let visitors use calculators without creating an account. Calculator inputs are generally processed in the browser by the page's JavaScript. We do not ask users to submit calculator values to us as part of normal calculator use.

This policy describes information that may be handled by the website, your browser, hosting infrastructure, external services, and advertising technology if it is enabled in the future.

Information you provide

If you contact us by email, the information you choose to include—such as your name, email address, message, and attachments—is processed by your email provider and ours so the message can be delivered and answered.

The contact-page message builder opens your email application; it does not submit the message to a separate website database through the page itself.

Calculator inputs and browser storage

Our standard calculator pages are designed to perform calculations in your browser. The site may use browser storage for limited preferences such as remembering whether you selected the light or dark theme.

Browser storage is controlled by your browser and can generally be cleared through browser privacy or site-data settings. Calculator-specific pages may describe additional behavior when a feature needs to save a local preference or downloaded result.

Technical and hosting information

Like most websites, hosting and network infrastructure may process standard request information needed to deliver pages and protect the service. This can include an IP address, browser or device information, requested URL, date and time, and security-related logs.

Retention and security practices can depend on the hosting and infrastructure providers used by the site.

Cookies, local storage, and advertising

The website may use local browser storage for site preferences. We do not publish a fake Google AdSense publisher ID or pretend that advertising is active when it is not.

If Google AdSense or another third-party advertising service is enabled, third-party vendors including Google may use cookies to serve ads based on a visitor's prior visits to this website or other websites. Google's use of advertising cookies can enable Google and its partners to serve personalized advertising. Visitors can manage personalized advertising through Google Ads Settings.

If additional advertising vendors or networks are used, this policy should be updated to identify the relevant vendors and choices. Consent notices may also be required depending on the visitor's location and the technologies enabled.

External links

Calculator articles may link to government agencies, educational resources, or other third-party websites. Those sites have their own privacy practices and are responsible for their own content, cookies, security, and data handling.

Children's privacy

Online Calculator Tools is a general-purpose calculator website and is not designed to collect personal information from children. If you believe a child has sent personal information to us through email, contact us so the situation can be reviewed.

Your privacy choices

• Use calculator pages without creating an account.
• Clear local storage and cookies using browser controls.
• Choose not to send us an email or include personal information in a message.
• If advertising technology is enabled, use available ad-personalization and consent controls where applicable.

Changes to this policy

We may update this Privacy Policy when website features, data practices, legal requirements, hosting arrangements, analytics, or advertising services change. The date shown at the top indicates the latest published revision.
