Privacy Policy

This Privacy Policy explains how Calculatorem handles information when you use the public calculator pages, contact form and related site features. It is written for this site specifically, not as a generic privacy template.

Calculator Inputs

Public calculator inputs are intended to be processed in your browser. When you type numbers, dates, grades or unit values into a calculator, those values are used to produce the result on the page. For ordinary public use, Calculatorem does not save those calculator inputs to a user account or build a personal profile from them.

You should still avoid entering sensitive information that the calculator does not need. For example, a date calculator does not need a legal case number, a grade calculator does not need a student ID and a unit converter does not need account information. If a page only asks for numbers or dates, keep the input limited to that task.

Messages Sent Through The Contact Form

If you send a message through the contact form, we collect the name, email address, subject and message you provide. We use that information to read your request, respond when appropriate, investigate reported calculator issues and keep a record of feedback that may improve the site.

Contact messages may also include technical details such as IP address and submission time. Those details help with spam prevention, abuse checks, security review and troubleshooting. We do not sell contact form messages.

Technical Data

Like most websites, the server may receive technical data when a page is requested. This can include IP address, browser type, device information, requested URL, referrer, time of request, error logs and basic performance information. This data is used to keep the site secure, diagnose problems and understand whether pages are loading correctly.

Technical logs are not meant to store the numbers you type into calculator forms. If an error report is created by a visitor, the visitor should choose what inputs to include in the message.

Cookies, Local Storage And Consent Choices

The public site uses a consent interface for optional cookies. Essential functionality can run without optional analytics or advertising cookies. Your cookie choice may be stored in your browser so the site can remember the choice instead of asking on every page.

A private session cookie is used for authorized site management. That private session is not required for public visitors to use calculator pages.

Analytics, Advertising And Third Parties

If Calculatorem adds analytics or advertising services, those services should respect the consent choice shown on the site. Optional analytics and advertising cookies should stay off unless the visitor allows them where consent is required.

Third-party providers may process limited technical information according to their own policies when their services are enabled. Examples could include analytics measurement, ad delivery, security tools or hosting infrastructure. Calculatorem should not send public calculator inputs to those services as personal calculator records.

Retention And Deletion

Contact messages may be kept while they are useful for support, correction history, abuse prevention or security review. You can ask us to delete a contact message you sent by writing to [email protected] from the same email address used in the form. We may keep limited records when needed for security, abuse prevention, legal compliance or legitimate site operation.

Children

Calculatorem is a general-use calculator site. It is not designed to collect personal information from children. Students may use grade or math calculators, but they should not send personal school records or account details through the contact form.

Contact

Privacy questions can be sent to [email protected]. If your question is about a specific message or page, include enough detail for us to identify it.
