Terms of Use
By using the 界 Kai extension, you agree to the terms below.
1. The service
界 Kai is an on-device browser tool that detects credential-harvesting UI — fake login windows, overlay phishing, browser-in-the-browser spoofs, cross-origin login forms and seed-phrase prompts — and can inform, warn, or block submission. It is explainable and runs locally.
2. "As is" & no warranty
界 Kai is provided "as is" and "as available" without warranties of any kind. Phishing evolves constantly; 界 Kai is a heuristic, additive detector and cannot guarantee detection or blocking of every threat, nor that every flag is malicious. It is one layer of defense in depth and does not replace your own judgment, your browser's protections, or other security measures.
3. Your responsibilities
- Use your own judgment before entering credentials or a recovery phrase anywhere.
- Curate your allowlist responsibly; trusting a site disables protection on it.
- Comply with the laws applicable in your region.
4. Privacy & limitation of liability
Your data is governed by our Privacy Policy, which is part of these terms; detection is on-device and nothing is sent off-device. To the maximum extent permitted by law, rmthreat.com is not liable for any direct, indirect, incidental or consequential damages arising from use of, or inability to use, the extension.
5. License & changes
界 Kai is released under the license in its repository; these terms govern your use of the published builds. We may update these terms from time to time and will update the date above. Continued use means you accept the updated terms. Questions: privacy@rmthreat.com.
