Privacy Policy

Last Updated: April 15, 2026

Welcome to AI Detector Checker (“we,” “us,” or “our”). This Privacy Policy explains what information we collect when you use our AI detector website, how we use and protect that information, and the choices you have regarding your data.

Detector-Checker AI is a free, no-login AI detection service. You can use the tool by pasting text directly or by uploading supported document files for text extraction and analysis. By using our website, you agree to the practices described in this Privacy Policy.

Important summary: We do not require account creation. We do not sell your submitted text, uploaded documents, or contact information. We do not use your submitted content to train AI models. Submitted text, uploaded files, and extracted document text are processed only to provide your AI detection result and are not stored after processing is complete.

What We Collect

We collect only the information needed to operate, secure, improve, and support our service.

  • Text Input and Uploaded Documents: When you paste text into our AI detector or upload a supported file, we process that content to generate a probability-based AI detection result. Supported file types may include PDF, DOCX, TXT, and RTF, currently up to the file-size limit shown in the interface, such as 5 MB. Uploaded files are processed to extract readable text for analysis. We do not store the original file, extracted text, or submitted text after the result is generated.
  • Document Metadata: Some uploaded documents may technically include metadata, file names, comments, tracked changes, hidden text, or embedded information. We do not need this information for our service and do not intentionally retain it. We recommend removing sensitive metadata before uploading any document.
  • Contact Data: If you contact us by email or through a contact form, we may collect your name, email address, and the content of your message. We use this information only to respond to your inquiry.
  • Usage and Technical Data: We may automatically collect limited technical information such as IP address, browser type, device information, pages visited, referring URLs, approximate location, timestamps, and server log data. We use this information for analytics, performance monitoring, fraud prevention, rate limiting, abuse detection, and security.
  • Cookies and Similar Technologies: We use cookies and similar technologies for analytics, advertising, cookie consent, and basic website functionality. These may include cookies from Google Analytics and Google AdSense.

Please do not submit highly sensitive personal information, confidential business documents, financial records, health information, government IDs, passwords, or other private data unless you are comfortable processing that content through our tool.

How We Use Information

  • To Provide the AI Detection Service: We use submitted text and uploaded documents only to extract text, analyze it, and display an AI detection result.
  • To Process Uploaded Files: Uploaded documents are temporarily processed so that readable text can be extracted and checked. Where temporary storage is technically required during extraction, it is used only for processing and then deleted after analysis is complete.
  • To Improve the Website: We use aggregated analytics to understand how visitors use our site, which pages are useful, and how we can improve performance and content.
  • To Display Ads: We use Google AdSense to support the free service. Advertising cookies may be used by Google and its partners to serve ads, measure ad performance, prevent fraud, and manage ad frequency.
  • To Maintain Security: We may use IP addresses, server logs, rate-limiting signals, and security data to prevent spam, automated abuse, scraping, attacks, misuse, and unauthorized access.
  • To Communicate With You: If you contact us, we use your provided information to respond to your message or request.

We do not use your submitted text, uploaded files, extracted document text, or AI detection results to train AI models. We also do not share submitted content with advertisers.

Uploaded Files and Submitted Content

Our detector is designed to analyze text. When you upload a supported document, the file is used only to extract readable text and run the AI detection analysis.

  • We do not permanently store uploaded files.
  • We do not permanently store extracted text.
  • We do not permanently store pasted text submissions.
  • We do not use submitted content for AI model training.
  • We do not sell, rent, or disclose submitted content to advertisers.
  • We do not create user accounts or long-term user profiles from submitted content.

AI detection results are probability-based review signals and should not be treated as absolute proof of authorship.

Cookies and Tracking Technologies

Cookies are small text files stored on your device when you visit a website. We use cookies and similar technologies for analytics, advertising, consent management, and essential site functionality.

  • Analytics Cookies: Google Analytics helps us understand website traffic, page performance, and user behavior in aggregated form. We do not use analytics data to identify individual users.
  • Advertising Cookies: Google AdSense and its advertising partners may use cookies to display ads, personalize ads where permitted, measure ad performance, prevent fraud, and limit how often ads are shown.
  • Essential Cookies: We may use minimal cookies for essential functions, such as remembering cookie consent choices or supporting basic site security.

You can control cookies through your browser settings. If you disable cookies, the core AI detection tool should still function, but analytics, advertising personalization, or consent preferences may be affected.

Google Analytics and Google AdSense

We may use Google Analytics to collect aggregated website usage statistics. Google Analytics may process information such as pages visited, device type, browser type, approximate location, referral source, and interaction data. Where available, we use privacy-friendly settings such as IP anonymization.

We may use Google AdSense to display advertisements. Google and its partners may use cookies or similar technologies to serve ads based on your visits to our site or other websites, where permitted by law and your consent settings.

We do not provide your submitted text, uploaded files, extracted document text, or AI detection results to Google Analytics or Google AdSense.

Service Providers

We may use trusted service providers to operate our website, host infrastructure, provide security, analyze traffic, display ads, process contact messages, and support the AI detection service. These providers may process limited information only as needed to provide their services to us and are not permitted to use your submitted content for their own purposes.

We may disclose information if required by law, legal process, security obligations, or to protect our rights, users, and service.

Data Retention

  • Submitted Text: Processed temporarily to generate your result, then discarded.
  • Uploaded Files: Temporarily processed for text extraction and analysis, then deleted after processing is complete.
  • Extracted Document Text: Used only to generate the AI detection result, then discarded.
  • Contact Messages: Kept only as long as needed to respond to your inquiry or comply with legal obligations.
  • Analytics Data: Retained according to our analytics settings and Google’s applicable retention policies.
  • Security and Server Logs: Retained for a limited period as needed for security, troubleshooting, fraud prevention, and legal compliance.

Data Security

We use reasonable technical and organizational measures to protect information processed through our website. These measures may include HTTPS encryption, access controls, firewalls, monitoring, rate limiting, abuse detection, and regular security updates.

No online service can guarantee absolute security. You use the service at your own risk, and you should avoid submitting sensitive or confidential information that is not necessary for AI detection.

Your Privacy Rights

Depending on your location, you may have rights to access, correct, delete, restrict, or object to certain processing of your personal information. You may also have the right to withdraw consent for optional cookies or request information about how your data is used.

If you are located in the EEA, UK, California, or another region with privacy laws, you may contact us to exercise your applicable rights. Because we do not create user accounts and do not retain submitted text or uploaded files after processing, we may have limited personal data available to access or delete.

California residents may have the right to know, delete, correct, and opt out of certain “sale” or “sharing” of personal information. We do not sell your submitted content or contact information for money. Where advertising cookies may be considered “sharing” under applicable law, you can manage preferences through cookie controls, browser settings, or Google ad settings.

Children’s Privacy

Our website is not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided personal information to us, please contact us and we will take appropriate steps to delete it.

International Users

Our website may be accessed from different countries. Your information may be processed in countries other than your own, including countries that may have different data protection laws. Where required, we rely on appropriate safeguards for international data transfers.

Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our service, legal requirements, security practices, advertising tools, analytics tools, or file processing features. When we update the policy, we will revise the “Last Updated” date above.
