MUGSHOT Terms of Service

Last updated: July 8, 2026

These Terms of Service (the “Terms”) set out the conditions for using the application “MUGSHOT” (the “App”) provided by MIZUKICHI LAB (“we,” “us,” or “our”). Anyone who uses the App (the “User”) shall use it having agreed to these Terms.

This is a reference translation. The Japanese version is the authoritative text; if there is any discrepancy between the Japanese version and a translation, the Japanese version prevails.

Article 1 (Application)

  1. These Terms apply to all relationships between us and the User concerning use of the App.
  2. The User is deemed to have agreed to these Terms at the moment they agree on the consent screen shown when first launching the App, or at the moment they use the App.

Article 2 (Nature of the App)

  1. The App is a supplementary theft-deterrence tool that detects suspicious activity against an unattended laptop or similar device (removal of the power cable, the user stepping away, nearby motion, tampering, and the like) and then sounds an alarm, captures photo evidence, sends notifications, and so on.
  2. The App does not guarantee the prevention or detection of theft, loss, damage, or any other harm. The App is not a substitute for security services, insurance, or any other professional service.
  3. Detection by the App may produce false positives or missed detections depending on the state of the device, OS behavior, permission settings, network conditions, hardware specifications, and other factors.

Article 3 (Disclaimer)

  1. The App is provided “AS IS,” without any warranty, whether express or implied. We make no warranty whatsoever as to merchantability, fitness for a particular purpose, accuracy, completeness, availability, or continued provision.
  2. To the maximum extent permitted by law, we bear no liability whatsoever for any damages arising out of the use of or inability to use the App and incurred by the User or a third party, including those in the following items, regardless of the nature of such damages (including direct, indirect, special, incidental, or consequential damages, and lost profits):
    • Theft, loss, damage, or destruction of the device, its accessories, or the data on the device
    • Failure to capture evidence photos, blurred photos, or photos whose content is not useful for identification
    • The alarm (siren) failing to sound, being delayed, being too quiet, or causing effects due to excessive volume
    • Non-delivery, delay, misdelivery, or missing content of notifications (such as ntfy)
    • False positives (triggering when it should not) or missed detections (failing to trigger when it should)
    • Excessive battery consumption, device heating, forced termination or sleep by the OS, or background restrictions
    • Defects, bugs, or stoppage of the App, or incompatibility with other software or hardware
  3. Even where we are found to bear some liability toward the User, the total amount of our liability shall be capped at the amount most recently paid to us by the User in connection with the event that caused the damages (as the App is provided free of charge, in principle 0 yen).
  4. The disclaimers in this Article do not apply to damages arising from our willful misconduct or gross negligence, or to any extent for which disclaimer is not permitted by law.

Article 4 (User’s Responsibilities)

  1. The User shall use the App at their own risk.
  2. The User shall use the App in a manner that does not violate applicable laws or public order and morals.
  3. Note on capturing evidence photos: The App takes photos with the device’s camera when it detects a breach. The User is responsible for confirming, at their own risk, that such photography does not infringe the privacy rights, portrait rights, or other rights of third parties, and for not using the App in places or situations where photography is prohibited or restricted (including changing rooms, bathhouses, and other places where photography may be illegal). The User bears all liability arising from photography.
  4. Note on the alarm sound: The User understands that the App’s alarm sound may affect the surroundings, and shall decide at their own risk whether to use it in public places or other settings where volume is restricted.
  5. Note on notification settings: The ntfy topic name functions in effect as a password. The User is responsible for setting a hard-to-guess topic name and for not disclosing it to third parties.
  6. The User shall, at their own cost and responsibility, resolve any dispute with a third party arising out of or in connection with the User’s use of the App or breach of these Terms, and shall indemnify and hold the Provider harmless from any claim brought against the Provider by a third party (including claims relating to the infringement of a third party’s privacy or likeness rights). If the Provider incurs any cost (including reasonable attorneys’ fees) in connection with such a claim, the User shall compensate the Provider for that cost.

Article 5 (Prohibited Conduct)

In using the App, the User shall not engage in any of the following:

  1. Acts that violate laws or public order and morals
  2. Acts that infringe the rights of third parties (privacy rights, portrait rights, property rights, etc.)
  3. Impersonating another person, or configuring the App on another person’s device without permission to monitor or photograph them
  4. Reverse engineering, decompiling, or the like of the App (except to the extent permitted by law)
  5. Acts that interfere with the operation of the App or that disadvantage us or third parties

Article 6 (Intellectual Property Rights)

All intellectual property rights in and related to the App belong to us or the rightful rights holders. These Terms do not transfer these rights to the User beyond the scope necessary to use the App.

Article 7 (Changes to or Suspension of the App)

We may change the content of the App, or suspend or discontinue its provision, without prior notice to the User. We bear no liability for damages incurred by the User as a result, in accordance with the provisions up to the preceding Article.

Article 8 (Changes to These Terms)

  1. We may change these Terms without individual notice to the User whenever we deem it necessary.
  2. When making a significant change, we may again request consent on the App’s consent screen or the like. If the User uses the App after a change, the User is deemed to have agreed to the changed Terms.

Article 9 (Governing Law and Jurisdiction)

  1. These Terms are governed by the laws of Japan.
  2. Any dispute arising between us and the User concerning the App or these Terms shall be subject to the exclusive agreed jurisdiction of the Japanese court having jurisdiction over our location as the court of first instance.

Article 10 (Language)

The Japanese version of these Terms is the authoritative text. Translations into English, Chinese, Korean, or other languages may be provided, but these are translations for reference only; if there is any discrepancy between the Japanese version and a translation, the Japanese version prevails.
