Privacy Policy

Effective Date: September 17, 2026

At matrixrrefsolver.com (“we,” “us,” or “the Site”), we respect the privacy of our visitors. This Privacy Policy explains what information may be collected when you use the Site, why it is collected, how it is used, and the choices available to you.

matrixrrefsolver.com is a free website that provides an RREF (Reduced Row Echelon Form) calculator and educational articles relating to matrices, linear algebra, and related mathematical topics.

1. Information We Do Not Ask You to Provide

You do not need to create an account, register, or provide personal information in order to use matrixrrefsolver.com.

We do not ask visitors to provide their name, email address, mailing address, telephone number, credit or debit card information, bank account information, passwords, or other account credentials.

The Site does not currently sell products or services and does not process payments.

2. Information Collected Automatically

Although we do not ask you to submit personal information, we use Google Analytics to understand how visitors use the Site.

Subject to the cookie-consent rules described below, Google Analytics may collect information about how you interact with matrixrrefsolver.com. This may include pages visited, time spent on pages, referring websites or search engines, general interaction information, browser type, device type, operating system, screen characteristics, approximate geographic location such as country or city, session information, and pseudonymous identifiers used to distinguish users or sessions.

We use this information primarily in aggregated form to understand how the Site is being used and to improve its calculators, articles, usability, and performance.

We do not intentionally use Google Analytics to determine the real-world identity of individual visitors.

3. Google Analytics

matrixrrefsolver.com uses Google Analytics, a web analytics service provided by Google.

Google Analytics helps us understand matters such as which pages visitors use, which articles are useful, how visitors reach the Site, how long people interact with particular pages, and whether particular parts of the Site need improvement.

Google Analytics may use cookies or similar technologies to distinguish visitors and sessions.

Google may process technical information, including an IP address, as part of providing the Analytics service. Google states that Google Analytics 4 does not log or store individual IP addresses.

Information processed through Google Analytics is also subject to Google's applicable privacy policies and data-protection terms.

4. Cookies and Similar Technologies

A cookie is a small piece of data that a website or service stores on a visitor's browser or device.

matrixrrefsolver.com may use cookies that are necessary for functions such as remembering a visitor's privacy or cookie-consent choices.

We also use Google Analytics cookies where the visitor has provided any consent required by applicable law.

Google Analytics commonly uses cookies including _ga, which is used to distinguish users, and _ga_<container-id>, which is used to maintain session information. Google's default expiration period for these cookies is two years, although the actual duration may vary depending on configuration and subsequent changes to Google's services.

Analytics cookies are not necessary for you to use the RREF calculator or read the Site's articles.

5. Cookie Consent for Visitors in the EEA and United Kingdom

For visitors in the European Economic Area (“EEA”) and the United Kingdom, analytics cookies and similar non-essential technologies are not activated unless the visitor has provided the required consent.

When applicable, you will be presented with a cookie-consent notice that allows you to accept or reject analytics cookies.

Rejecting analytics cookies will not prevent you from using the RREF calculator, reading articles, or otherwise accessing the ordinary content of matrixrrefsolver.com.

We do not treat continued browsing, scrolling, inactivity, or merely closing a notice as consent to analytics cookies.

Where consent is required, Google Analytics is configured so that analytics storage is denied until the visitor provides consent.

You may withdraw or change your consent at any time using the cookie or privacy settings made available on the Site. Withdrawing consent will not affect the lawfulness of processing that occurred while valid consent was previously in effect.

6. Legal Basis for Analytics Processing

Where applicable data-protection law requires consent before analytics technologies can be used, we rely on your consent.

Consent is optional. You may refuse analytics cookies without losing access to the Site's calculator or educational content.

Where consent has been refused or withdrawn, we will not intentionally activate Google Analytics cookies that require such consent.

7. How We Use Analytics Information

Analytics information is used to understand how visitors use matrixrrefsolver.com and to improve the Site.

For example, the information may help us determine which calculator features are useful, which educational articles receive the most interest, where visitors encounter problems, how the Site performs on different devices, what topics visitors are interested in, and what improvements or new content may be worthwhile.

We do not sell Google Analytics information to third parties.

8. Calculator Use

The RREF calculator is intended for mathematical input.

You do not need to provide personal information to use the calculator.

You should not enter names, email addresses, financial information, passwords, confidential information, medical information, or other personal information into calculator input fields.

The calculator should be used only for mathematical values and expressions relevant to the calculation being performed.

9. Data Retention

Google Analytics provides configurable data-retention settings.

The length of time analytics information is retained may depend on our Google Analytics configuration, the type of information involved, and Google's applicable retention practices.

We aim to retain analytics information only for as long as it is reasonably useful for understanding and improving matrixrrefsolver.com.

Cookies stored on your device may remain there until they expire or until you delete them through your browser, unless they are removed earlier.

10. Sharing and Processing of Information

We do not sell, rent, or trade visitors' personal information.

Because we use Google Analytics, information collected through that service may be processed by Google as necessary to provide analytics services.

Google may process information in countries outside the country in which you live. Where European or UK data-protection rules apply to international transfers, Google states that it uses applicable legal safeguards and data-transfer mechanisms under its data-protection terms.

Information may also be disclosed where required by applicable law, legal process, court order, or a valid request from an appropriate governmental or regulatory authority.

11. Your Privacy and Cookie Choices

You may reject analytics cookies when the Site presents you with a consent request.

If you previously accepted analytics cookies, you may later change your preference using the Site's cookie or privacy settings.

You can also remove previously stored cookies using your browser settings and may configure your browser to block some or all cookies.

Google also provides tools and browser controls that may allow users to limit Google Analytics tracking.

Blocking or rejecting analytics cookies does not prevent you from using the primary functions of matrixrrefsolver.com.

12. Privacy Rights for EEA and UK Visitors

Depending on the circumstances and applicable law, visitors in the EEA or United Kingdom may have rights relating to personal data about them, including rights of access, correction, deletion, restriction, objection, data portability, and withdrawal of consent.

Some of these rights apply only in particular circumstances.

Because matrixrrefsolver.com does not require user accounts and does not ordinarily collect names, email addresses, or similar direct identifiers, we may not always be able to associate particular analytics information with a specific individual.

You may also have the right to lodge a complaint with the data-protection supervisory authority responsible for your country or region.

13. International Data Processing

Google operates services internationally. As a result, information processed through Google Analytics may be processed in countries other than the country in which you are located.

Google maintains data-protection terms and mechanisms relating to international data transfers. Visitors who would like additional information about Google's processing practices should review Google's privacy and data-protection documentation.

14. Children's Privacy

matrixrrefsolver.com is a general mathematical and educational website and is not specifically directed toward children.

We do not knowingly ask children to provide names, email addresses, payment information, or other personal information through the Site.

If we become aware that personal information has been collected from a child in circumstances where applicable law requires its deletion or other action, we will take reasonable steps to address the matter.

15. Links to Other Websites

Our articles or other pages may contain links to third-party websites.

When you leave matrixrrefsolver.com and visit another website, that website's own privacy practices and policies apply.

We are not responsible for the privacy practices, security, content, or operation of third-party websites.

16. Changes to Your Cookie Preferences

Where a cookie-consent mechanism is provided, you may change your analytics preference after your initial choice.

A link such as Cookie Settings, Privacy Settings, or a similar control will be made available on the Site so that you can review or change your preference.

If you withdraw consent, analytics technologies requiring that consent will no longer be intentionally activated for future use of the Site, subject to the operation of the consent-management system.

You may separately delete cookies already stored on your device through your browser settings.

17. Changes to This Privacy Policy

We may update this Privacy Policy if the Site changes, if we add or remove third-party services, if our analytics practices change, or if applicable privacy requirements change.

When this policy is updated, the revised version will be posted on this page and the Effective Date at the top of the policy will be updated.

Visitors are encouraged to review this page periodically.
