Terms of Use
Acceptance of Terms
By accessing or using CheckThatURL at checkthaturl.com ("the Service"), you agree to be bound by these Terms of Use. If you do not agree, do not use the Service.
These terms apply to all users of the Service including individuals, organisations, and institutional clients.
Service Description
CheckThatURL is a URL analysis and phishing detection platform. The Service includes:
- A free URL scanner accessible via the web interface and API
- Hunter — an autonomous threat hunting module (commercial)
- Radar — a threat intelligence dashboard (commercial)
We reserve the right to modify, suspend, or discontinue any part of the Service at any time with or without notice.
Acceptable Use
You may use the Service for lawful security research, threat detection, and URL analysis purposes. You agree not to:
- Use the Service to scan URLs for the purpose of evading detection for malicious activity
- Attempt to reverse-engineer, scrape, or systematically extract the model or its outputs at scale
- Circumvent rate limits or access controls
- Submit URLs containing personally identifiable information of third parties without their consent
- Use the Service in any manner that violates applicable law
Institutional access to the API is subject to a separate usage agreement.
Accuracy & Limitations
CheckThatURL uses machine learning and heuristic analysis. No automated system achieves perfect accuracy. The Service may produce:
- False positives — legitimate sites flagged as suspicious or phishing
- False negatives — malicious sites classified as legitimate
- Partial results — when a site is unreachable, protected by anti-bot measures, or times out
You are solely responsible for decisions made on the basis of scan results. We recommend corroborating results with additional verification, especially for high-stakes security decisions.
Intellectual Property
The Service, including its machine learning models, source code, visual design, and documentation, is the intellectual property of CheckThatURL and its contributors.
The core scanner is planned for open-source release under the Apache 2.0 licence for use by African financial institutions. Hunter and Radar remain proprietary commercial software.
Scan results produced by the Service are provided to you under a limited, non-exclusive licence for your own security use. You may not resell or redistribute scan results as a commercial service without a separate agreement.
Disclaimer of Liability
The Service is provided "as is" and "as available" without warranties of any kind, express or implied, including fitness for a particular purpose or non-infringement.
To the maximum extent permitted by applicable law, CheckThatURL shall not be liable for any direct, indirect, incidental, consequential, or punitive damages arising from your use of or reliance on the Service, including but not limited to financial losses, security incidents, or data breaches resulting from decisions informed by scan results.
Service Availability
We aim to maintain high availability but do not guarantee uninterrupted service. Scheduled maintenance, infrastructure incidents, or third-party service outages may affect availability. We are not liable for downtime or service interruptions.
Changes to Terms
We may update these Terms at any time. Changes will be reflected by an updated "last updated" date at the top of this page. Continued use of the Service after changes constitutes acceptance of the new Terms.
Governing Law
These Terms shall be governed by and construed in accordance with applicable law. Any disputes shall be subject to the exclusive jurisdiction of the relevant courts, unless otherwise agreed in a separate institutional agreement.
For questions regarding these Terms, contact us through the CheckThatURL GitHub repository or institutional contact channels.
