Privacy Policy

Last updated: August 2026

This Privacy Policy explains how Detect AI ("we", "us", or "our"), available at https://detect-ai.org, collects, uses, and protects information when you use our free online AI content detector. Detect AI is operated by the team behind GPTKiller (https://gptkiller.kr). By using our website, you agree to the practices described below. Please read this policy carefully so you understand your rights and our responsibilities.

Information we collect

Detect AI does not require an account, signup, or login, so we do not ask you for your name, email address, or password to use the detector. When you visit our site, our servers and third-party providers may automatically receive standard technical data such as your IP address, browser type, device information, referring pages, and timestamps. This information is used to operate, secure, and improve the service and to serve advertising, as described in later sections.

To analyze content, you paste text into the detector and it is sent to our detection API, where it is processed in real time to return a human-versus-AI probability score. The text you submit is not stored or logged on our servers after the response is returned to you. We do not retain your submissions, we do not build a profile from them, and we do not sell any personal data to third parties.

Cookies and similar technologies

We and our partners use cookies and similar technologies (such as web beacons and local storage) to make the site work, remember preferences, measure traffic, and deliver advertising. Some cookies are essential for the site to function, while others are optional and used for analytics or personalized ads. You can control or delete cookies through your browser settings at any time, though disabling some cookies may affect how parts of the site behave.

Analytics

We may use analytics tools such as Google Analytics to understand how visitors find and use Detect AI, including which pages are viewed and how long visits last. These tools set their own cookies and may collect aggregated, pseudonymous usage data, such as approximate location and device type, to help us improve the product. Analytics data is used in aggregate and is not used to identify you personally. You can learn more from Google's privacy policy at https://policies.google.com/privacy.

Advertising

Detect AI is free to use and is supported by advertising. We display ads through Google AdSense, which allows Google and its advertising partners to show ads on our pages. Advertising helps us cover the cost of running the detection service and keep it available at no charge to you.

Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google's use of advertising cookies, including the DoubleClick cookie, enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet. These cookies may be used to show you personalized advertising that is more relevant to your interests.

You may opt out of personalized advertising by visiting Google Ads Settings at https://www.google.com/settings/ads. You can also opt out of the use of cookies for personalized advertising by many third-party vendors by visiting https://www.aboutads.info/choices. For more detail on how Google uses information from sites that use its services, please see Google's privacy policy at https://policies.google.com/privacy.

Third-party services

We rely on trusted third-party providers to operate Detect AI, including our detection API, hosting and content-delivery providers, analytics tools, and advertising networks such as Google. These providers process data only as needed to perform their services and are subject to their own privacy policies, which we encourage you to review. We are not responsible for the privacy practices of external websites that you may reach through links or advertisements on our site.

Data retention

We keep personal data only for as long as necessary to fulfill the purposes described in this policy or as required by law. As noted above, the text you submit to the detector is not stored after your result is returned. Technical logs and analytics data are retained for a limited period to support security, troubleshooting, and service improvement, after which they are deleted or anonymized.

Your rights (GDPR & CCPA)

Depending on where you live, you may have rights over your personal data. Under the GDPR, residents of the European Economic Area and the UK may request access to, correction of, deletion of, or restriction of their personal data, may object to certain processing, and may request data portability. Under the CCPA, California residents may request disclosure of the personal information we collect, request its deletion, and opt out of any sale of personal information. We do not sell your personal data. To exercise any of these rights, contact us using the details below.

Children's privacy

Detect AI is not directed to children under the age of 13 (or the minimum age required in your jurisdiction), and we do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us and we will take reasonable steps to delete it. Parents and guardians who have questions about our practices are welcome to reach out at any time.

International data transfers

Detect AI is operated with providers that may process and store data in countries other than the one in which you live, including outside the European Economic Area. Where personal data is transferred internationally, we and our providers take steps designed to ensure it receives an adequate level of protection, such as relying on recognized legal transfer mechanisms and contractual safeguards. By using the service, you understand that your information may be processed in these locations.

Changes to this policy

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, or legal requirements. When we make material changes, we will revise the "Last updated" date at the top of this page and, where appropriate, provide additional notice. We encourage you to review this policy periodically so that you stay informed about how we protect your information.

If you have questions about this Privacy Policy or wish to exercise your privacy rights, you can reach us by email at support@detect-ai.org. You may also use our contact page to get in touch. We aim to respond to all legitimate requests within a reasonable timeframe and in accordance with applicable law.
