Privacy Policy

Effective Date: September 1, 2026  |  Last Updated: September 1, 2026

This Privacy Policy explains how Slope-Calculator.org ("we," "us," or "our") handles information in connection with your use of https://slope-calculator.org/ (the "Website"). We are committed to protecting your privacy and being transparent about our limited data practices. By using the Website, you acknowledge that you have read and understood this Privacy Policy.

1. Scope of This Policy

This Policy applies to information processed through the Website. It does not apply to third-party websites, services, or advertisers that may be linked from or displayed on the Website. Those third parties operate under their own privacy policies, which we encourage you to review.

2. Information We Collect and Do Not Collect

We do not require account registration and do not intentionally collect profile information directly from visitors. Any values you enter into our calculators run in your browser and are not transmitted to or stored by us. Specifically:

  • We do not offer user registration or user accounts.
  • We do not require you to provide your name, email address, or other personal contact details in order to use the Website.
  • We do not offer third-party login (for example, Google or Facebook sign-in).
  • We do not build advertising or behavioral profiles of individual visitors ourselves, and we do not sell personal information.

However, some personal information may still be processed in connection with your visit — for example, if you email us, or through cookies, analytics, advertising, and standard server logs, as described below. Where this happens, it is largely carried out by the third-party services and providers we use, under their own privacy policies.

3. Information Processed Automatically

We do not build profiles of visitors on our own systems. However, technical information may be processed by the third-party services we use (Google Analytics and Google AdSense) and generated in standard server logs by our hosting and content-delivery providers, including:

  • IP address (which may be truncated or anonymized by the relevant provider).
  • Browser type and version, device type, and operating system.
  • Referring and exit pages, pages viewed, and the date and time of your visit.
  • General, approximate geographic location derived from your IP address.
  • Interaction data, such as clicks and time spent on pages.

This information is collected and processed by those providers under their own privacy policies. We generally access it through aggregated reports and do not intentionally use it to identify individual visitors.

4. Cookies and Similar Technologies

We do not use cookies to collect directly identifying personal information such as your name or email address. The cookies used on the Website are set by the third-party services we use (Google Analytics and Google AdSense). For full details about these cookies and how to manage or disable them, please see our separate Cookie Policy.

5. Google Analytics

We use Google Analytics, a web analytics service provided by Google LLC, to help us understand how visitors engage with the Website. Google Analytics uses cookies and similar identifiers to collect standard internet log information and visitor behavior information.

In providing this service, Google may process online identifiers, cookie identifiers, IP-derived information, and event data. We generally access Google Analytics through aggregated reports and do not intentionally use it to identify individual visitors.

You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on (tools.google.com/dlpage/gaoptout). For more information, see Google's Privacy Policy (policies.google.com/privacy).

6. Advertising and Google AdSense

The Website is supported by advertising. We use Google AdSense, an advertising service provided by Google LLC, to display ads. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to the Website and other websites.

  • Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to the Website and/or other sites on the internet.
  • You may opt out of personalized advertising by visiting Google Ads Settings (google.com).
  • You may also opt out of some third-party vendors' use of cookies for personalized advertising at aboutads.info or youronlinechoices.eu (for users in Europe).

For more information about how advertising and affiliate links work on the Website, please also review the Advertising and Affiliate Disclosure section of our Disclaimer.

7. How We Use Information

The limited information described above is used to:

  • Operate, maintain, and secure the Website.
  • Analyze traffic and usage trends to improve content and performance.
  • Display and measure advertising.
  • Detect, prevent, and address technical issues, fraud, or abuse.
  • Comply with applicable legal obligations.

8. Legal Bases for Processing (EEA/UK Visitors)

To the extent the General Data Protection Regulation (GDPR) or the UK GDPR applies to processing of your information, we rely on the following legal bases:

  • Consent: For non-essential cookies and similar technologies — including analytics and advertising cookies — where required by law, we rely on your consent, which you may withdraw at any time.
  • Legitimate interests: For essential website operation, security, and the prevention of fraud and abuse, we rely on our legitimate interest in providing, maintaining, and protecting a functional and secure Website. We have weighed these interests against your rights and freedoms and limit this processing to what is necessary for those purposes.
  • Legal obligation: Where processing is necessary to comply with the law.

9. Your Rights Under the GDPR (EEA/UK)

To the extent the GDPR or UK GDPR applies, you have the right to: access the personal data held about you; request correction or erasure; restrict or object to processing; data portability; and withdraw consent at any time. You also have the right to lodge a complaint with your local data protection authority. To exercise these rights, contact us at the email address below. Because we do not maintain accounts, we may need additional information to verify your request, and in some cases we may be unable to identify data associated with a specific individual.

10. Your Rights Under California Law (CCPA/CPRA)

To the extent the California Consumer Privacy Act (as amended by the CPRA) applies to us, California residents have certain rights regarding their personal information, including the right to know what personal information is collected, the right to request deletion, the right to correct inaccurate information, and the right to opt out of the "sale" or "sharing" of personal information.

We do not sell your personal information for money. However, our use of advertising technologies may constitute "sharing" for cross-context behavioral advertising, and may constitute a "sale" under certain state privacy laws. You can opt out by adjusting your cookie choices, using the opt-out links in Sections 5 and 6, or, where the CCPA applies and our systems support it, by enabling a Global Privacy Control (GPC) signal in a supported browser, which we treat as a valid opt-out request. Where we have actual knowledge that a user is under 16, we do not sell or share their personal information without opt-in consent (from the user if aged 13 to 15, or from a parent or guardian if under 13).

You have the right not to receive discriminatory treatment for exercising your privacy rights. To make a request, contact us at the email address below.

11. Data Retention

We do not retain personal information about visitors in a directly identifiable form on our own systems. If you email us, we keep your message only as long as reasonably necessary to respond to and manage your inquiry. Google Analytics data is retained for the period configured in our Google Analytics account (event-level data is typically retained between 2 and 14 months); standard technical logs generated by our hosting and content-delivery providers are generally kept for a short period (commonly up to about 90 days) in accordance with those providers' terms, privacy policies, and our configuration; and any cookie-consent records are kept only as long as needed to evidence your choice.

12. Data Security

We and our service providers take reasonable technical and organizational measures to protect the information processed through the Website. However, no method of transmission over the internet or method of electronic storage is completely secure, and we cannot guarantee absolute security.

13. International Data Transfers

The Website is operated with a global audience in mind. Our third-party providers (such as Google) may process data in the United States and other countries. Where required, these providers rely on appropriate safeguards for international data transfers, for example the European Commission's Standard Contractual Clauses, as described in their own privacy and data-transfer documentation.

14. Third-Party Links

The Website may contain links to third-party websites and services. We are not responsible for the privacy practices or content of those third parties. We encourage you to read the privacy policies of any website you visit.

15. Children's Privacy

The Website is intended for a general audience and is not directed to children under 13. Consistent with the U.S. Children's Online Privacy Protection Act (COPPA), we do not knowingly collect personal information from children under 13. If you believe that a child under 13 has provided personal information through the Website, please contact us and we will take appropriate steps to delete it.

16. Do Not Track

Some browsers offer a "Do Not Track" (DNT) signal. Because there is no consistent industry standard for DNT, the Website does not currently respond to DNT signals. We do, however, honor recognized opt-out mechanisms such as the Global Privacy Control where required.

17. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. When we do, we will revise the "Last Updated" date above and post the updated Policy on this page. Where required by law, we will seek your consent to any material changes.
