Privacy Policy

This Privacy Policy explains how Pattern Index ("we", "us", or "our") collects, uses, and protects information when you use patternindex.io (the "Site") and the related tests, articles, and AI-generated protocols (collectively, the "Service").

This Policy is written in general terms and is not a complete summary of all applicable legal requirements. Depending on where you live, additional rights and obligations may apply under local privacy laws.

1. Information we collect

The Service is designed to minimize the amount of personal data we process. In practice, information we may collect falls into the following categories:

1.1. Information you provide directly

When you use our tests or contact us, you may choose to provide:

• contact details such as an email address (for example, if you write to us or subscribe to updates);
• responses to test questions and other input you provide to the Service;
• any other information you voluntarily send to us.

1.2. Usage and technical data

When you access the Site, some technical information is typically collected automatically by your browser or device, such as:

• IP address and approximate region or country;
• browser type and version, device type, operating system;
• pages visited, time and date of visit, referring pages.

This kind of data is commonly used to keep the Site secure and to understand how people use the Service in aggregate (for example, which pages are visited most often). [web:198][web:208]

1.3. Cookies and similar technologies

The Site may use cookies or similar technologies to support basic functionality, such as remembering certain preferences or enabling analytics. You can control cookies through your browser settings. If we use third-party analytics or measurement tools, those providers may also set cookies or similar identifiers; please refer to their respective policies for details. [web:208][web:209]

2. How we use information

We use the information described above for the following purposes:

• to operate, maintain, and improve the Site and Service;
• to generate test results and AI-based protocols based on the input you provide;
• to monitor performance, detect problems, and protect the security of the Service;
• to answer questions or respond to messages you send us;
• to comply with legal obligations and enforce our Terms of Service.

We do not sell your personal information to third parties. If we use third-party providers (for example, analytics or infrastructure services), they act on our behalf and are only allowed to use the data as needed to provide their services to us. [web:198][web:204]

3. AI-generated content and data

The Service uses AI systems to generate test content, explanations, and protocols. When you interact with these features, your inputs (for example, answers to test questions) may be sent to AI providers to generate the relevant output.

We aim to limit inputs to what is necessary for the Service to work, and we encourage you not to include directly identifying information (such as full names, addresses, or identification numbers) in free-text fields. Where feasible, we configure AI tools and infrastructure so that your data is not used to train general-purpose models beyond our use of the Service. [web:201][web:204]

4. Legal bases (for users in the EU/EEA)

If you are located in the European Economic Area, the United Kingdom, or a region with similar laws, we process your personal data based on one or more of the following legal grounds:

• Consent – where you have given clear consent (for example, when you choose to send us an email or submit information);
• Contract – where processing is necessary to provide the Service you requested;
• Legitimate interests – such as improving the Service, keeping it secure, and understanding how it is used, where these interests are not overridden by your rights and freedoms;
• Legal obligation – where we must process data to meet applicable legal requirements. [web:203][web:206][web:209]

5. Data retention

We keep personal data only for as long as reasonably necessary to fulfil the purposes described in this Policy, including:

• to provide the Service and maintain your interactions with it;
• to meet legal, accounting, or reporting requirements;
• to resolve disputes and enforce our agreements.

Where data is no longer needed, we take steps to delete or anonymize it.

6. How we protect information

We use reasonable technical and organizational measures to protect information against unauthorized access, loss, or misuse. However, no method of transmission over the internet or method of electronic storage is completely secure, and we cannot guarantee absolute security. [web:198][web:209]

7. Your rights

Depending on where you live, you may have certain rights in relation to your personal data, such as the rights to:

• access the personal data we hold about you;
• request correction of inaccurate or incomplete data;
• request deletion of your personal data, subject to legal exceptions;
• object to or restrict certain types of processing;
• withdraw consent where processing is based on consent;
• lodge a complaint with a data protection authority in your region.

To exercise any of these rights, you can contact us using the details provided below. We may need to verify your identity before processing certain requests. [web:203][web:209]

8. Third-party services

The Service may contain links to third-party websites or services that are not controlled by us. This Privacy Policy does not cover those services, and we are not responsible for their content or privacy practices. We encourage you to review the privacy policies of any third-party services you use. [web:198][web:209]

9. Children's privacy

The Service is not intended for children under the age of 18, and we do not knowingly collect personal data from children. If you believe that a child has provided us with personal information, please contact us so that we can take appropriate steps to delete it. [web:198]

10. Changes to this Privacy Policy

We may update this Privacy Policy from time to time. When we make material changes, we will update the "last updated" date at the top of this page. Your continued use of the Service after changes take effect indicates that you have read and understood the updated Policy. [web:198][web:206]
