Terms of Service

You may request a diagnosis only for domains you own, or for domains whose owner has authorized you to have them diagnosed. You agree to this each time you request a diagnosis or register a domain, and we record the date and time, source IP address and browser type of that consent.

The non-intrusive quick diagnosis uses only publicly available information and responses to ordinary requests. Active testing is carried out only when you hold legitimate administrative authority over the target domain and both ownership verification and your consent to the testing have been recorded.

• Requesting a diagnosis of, or registering, a domain without its owner's authorization
• Requesting active testing of a domain you have no authority over
• Using diagnosis results to attack the target or for any other unlawful purpose
• Interfering with the operation of the Service, or any conduct that violates laws or public order and morals

Fees for paid plans are as shown on the pricing page. Monthly plans renew automatically every month until you cancel, and a cancellation takes effect from the next renewal date.

Diagnoses show results only within the scope that could be checked; they do not guarantee that every vulnerability will be found or that damage will be prevented. You are responsible for decisions and actions you take based on the results.

If we are liable for damages in connection with the Service, our liability is limited to the total fees we received from you in the preceding 12 months. This limit does not apply in cases of our wilful misconduct or gross negligence.

These terms are governed by the laws of Japan. The Tokyo District Court has exclusive jurisdiction as the court of first instance over any dispute relating to the Service.
