MUGSHOT Terms of Service

Document version: 3

Effective and last updated: July 11, 2026

These Terms govern use of the MUGSHOT application (the “App”) provided by 株式会社MIZUKICHI Lab (the registered Japanese company name; “we,” “us,” or “our”). A user may use the App after reviewing and accepting these Terms on the consent screen shown at first launch or another appropriate time.

This is a reference translation. The Japanese version is authoritative, subject to mandatory law.

Article 1 (Application)

  1. These Terms apply to the relationship between us and the user concerning the App.
  2. Terms of an app store or other distributor may also apply. Mandatory law and applicable distributor terms prevail in the event of a conflict.

Article 2 (Nature of the App)

  1. The App is a supplementary theft-deterrence tool that may detect supported suspicious events and provide an alarm, on-device photo storage explicitly enabled by the user, and text notifications. Public distribution builds disable external upload of evidence photos.
  2. The App does not guarantee prevention or detection of theft, loss, or damage, or delivery of an alert. It is not a substitute for security, insurance, emergency calling, or another professional service.
  3. OS behavior, permissions, network conditions, hardware, and placement can cause false positives, missed detections, delayed or undelivered notifications, or unavailable features. Test the App in your own environment before relying on it.
  4. Monitoring operates only while the App process is running. It does not continue after the App quits or is forcibly terminated, or after OS shutdown or restart, and it does not start or resume automatically.

Article 3 (Warranty and scope of liability)

  1. We provide the App with reasonable care, but, to the extent permitted by law, do not warrant fitness for a particular purpose, completeness, uninterrupted availability, or error-free operation.
  2. If our ordinary negligence causes loss, we are responsible for direct, actual, and ordinary loss foreseeably caused by that negligence. Our aggregate liability is reasonably capped at the greater of the amount the user paid us for the App during the 12 months before the loss or JPY 10,000. Special, indirect, and lost-profit damages are excluded unless we foresaw or could have foreseen them.
  3. These limits do not apply to our intentional misconduct or gross negligence, death or personal injury, or liability that cannot be limited under the Consumer Contract Act or other mandatory law. These Terms do not restrict a consumer’s statutory rights.
  4. Theft, unclear photos, alarm failure or excessive volume, failure to change or restore system output volume on supported platforms, temporary effects on other apps’ volume, delayed or failed notifications, battery drain, heat, OS termination, and compatibility issues are inherent risks. This paragraph does not categorically exclude liability imposed by law.

Article 4 (Safe and lawful use)

  1. Follow applicable law, facility rules, and third-party rights, and use the App only on a device you control. Do not install it on another person’s device to monitor or photograph them without permission.
  2. Camera use occurs only after explicit opt-in. Do not use it in changing rooms, bathing facilities, private areas, or other places where photography is prohibited or restricted, and respect privacy and likeness rights.
  3. The siren can be loud. On Android, macOS, and Windows, the App may temporarily set system output volume to the configured level during a breach and attempts restoration on disarm or stop; either operation can fail and other apps’ volume may be affected. It does not change system output volume on iOS. Do not use it close to ears, while headphones are connected, where quiet is required, or where it could create danger. Test safe volume and restoration first.
  4. Select only custom audio that you have the right to copy and play.
  5. Use a long, unpredictable ntfy topic as a secret and do not disclose it. Do not include secrets or sensitive information in notifications.

Article 5 (Prohibited conduct)

Users must not violate law or public order, infringe third-party rights, monitor or photograph without authorization, interfere with a service, gain unauthorized access, analyze or modify the App beyond what law permits, or use it to harm anyone.

Article 6 (Third-party claims)

If a user’s intentional or negligent breach of these Terms causes a third-party claim against us, the user will compensate us, within their share of responsibility, for reasonable and direct costs and losses actually incurred. This provision does not transfer our responsibility to the user and does not apply where prohibited by consumer or other mandatory law.

Article 7 (Intellectual property)

Rights in the App and materials we provide belong to us or their lawful owners. These Terms do not transfer rights beyond what is necessary to use the App. Rights in user-selected custom audio remain with its owner.

Article 8 (Changes, suspension, and discontinuation)

We may change, suspend, or discontinue the App for reasonable reasons such as safety, law, OS or distribution requirements, and maintenance. Except for urgent security action, we will give reasonable advance notice where user impact is substantial.

Article 9 (Changes to these Terms)

  1. We may change these Terms where there is a reasonable reason, such as a change in law, features, or security, and the change is reasonable in light of the purpose of use.
  2. We will normally announce the reason, content, and effective date in the App or on the website before effectiveness. In an emergency, we will notify users as soon as reasonably possible.
  3. We will request renewed explicit consent where a change is materially adverse or consent is required by law. A user who does not agree may stop using the App before the change takes effect.

Article 10 (Governing law, disputes, and language)

  1. These Terms are governed by Japanese law. Courts in Japan with jurisdiction under applicable law will hear disputes at first instance. Mandatory consumer rights concerning local law or venue are not excluded.
  2. The Japanese version is authoritative in the event of a discrepancy, to the extent consistent with mandatory law.
