免責事項・重要なお知らせ

最終更新日：2026年7月2日
発効日：2026年7月2日（バージョン 1.1）

このページは、「みまもり」アプリ（以下「本アプリ」）をご利用いただくにあたり、必ず知っておいていただきたいことを、丁寧にご説明するものです。本アプリは、一人暮らしのご高齢の方の見守りをお手伝いするアプリですが、安全や生命を保証できるものではありません。本ページの内容をご了承いただいたうえでご利用くださいますよう、お願い申し上げます。

⚠️ 重要：緊急のときは、本アプリだけに頼らず、必ず 119 番（消防・救急）へご連絡ください。

1. はじめに — 本アプリの位置づけ

本アプリ「みまもり」は、ご家族による見守りを補助するためのソフトウェアです。スマートフォンに搭載された加速度センサーや GPS などの情報をもとに、ご高齢の方の不活動・転倒・SOS を検知し、ご家族（ガーディアン）に通知します。

ただし、本アプリは：

医療機器ではありません。健康状態の診断・治療・予防を目的としたものではなく、薬機法（医薬品医療機器等法）上の医療機器としての承認・認証も受けていません。
緊急通報サービスではありません。119 番や 110 番のような公的な緊急通報インフラと直接連携しているものではなく、本アプリの通知がご家族（ガーディアン）以外に届くことはありません。
安全保証サービスではありません。本アプリを導入したことで「絶対に異変に気付ける」ことを保証するものではなく、後述するさまざまな理由により検知や通知が遅れたり、行われない可能性があります。

本アプリは、「気付ける可能性」を高めるための補助ツールとお考えください。

なお、本アプリは 16 歳以上の方を対象としており、見守られるシニアユーザーご本人の同意のもとでご利用いただくことを前提としています。

2. 検知や通知が届かない・遅れる主な原因

本アプリは、技術的にどうしても完全な検知・通知を保証できません。以下のような状況では、検知や通知が遅れる、または行われないことがあります。具体例を挙げてご説明します。

2-1. 通信回線の障害・遅延

通知は、お使いのスマートフォンから Google のクラウドサーバー（Firebase）を経由して、ご家族のスマートフォンに届きます。経路のどこかで通信が途絶えたり遅延したりすると、通知が届かない・遅れることがあります。

例：ご高齢の方の自宅が電波の弱い地域である
例：Wi-Fi ルーターの故障・電源切断
例：通信会社の障害（数年に一度発生する規模の大規模通信障害も含みます）

2-2. 端末のバッテリー切れ・電源 OFF・故障

端末の電源が入っていなければ、本アプリは動作しません。バッテリーが切れた・電源が切られた・端末が壊れた、というときは、検知も通知も行われません。

本アプリには「バッテリー残量低下」のお知らせ機能があります（既定 5% 以下で通知）。ご家族（ガーディアン）が気付きやすくなる工夫はしていますが、通知到着の前に電源が切れることもあり得ます。

2-3. OS によるアプリの強制終了・動作制限

Android OS は、バッテリーを節約するためや動作の安定のために、アプリの動作を自動的に制限することがあります。

例：「バッテリー最適化」機能により、バックグラウンドでの動作が制限される
例：Android が本アプリを強制終了する（メモリ不足時など）
例：「アプリの強制停止」をご本人や別のアプリが実行する
例：一部のメーカーの端末には、標準の Android より強力な独自の省電力機能・「アプリ自動終了」機能が搭載されており、「バッテリー最適化の除外」を設定済みでも見守りが停止することがある

本アプリは、初回起動時に「バッテリー最適化の除外」をお願いしていますが、設定が正しく適用されていないと動作が止まる場合があります。メーカー独自の省電力設定がある端末では、その設定でも本アプリを除外し、アプリ内の見守り稼働表示を定期的にご確認ください。

2-4. GPS の精度限界・取得不能

位置情報は GPS 衛星からの電波を受信して取得します。以下のような場所では、正確な位置を取得できない、または位置情報そのものが取得できないことがあります。

屋内（特に地下、鉄筋コンクリート建造物の中、エレベーター内）
高層ビル街（電波の反射により誤差が大きくなる）
山間部・トンネル内
端末が機内モードになっている、位置情報サービスが OFF になっている

なお、SOS 等の通知に添付される位置情報は「最後に取得できた位置」であり、最大で約 15 分前（それ以降取得できていない場合はさらに前）のものであることがあります。実際の位置と異なる場合があります。

2-5. 加速度センサーの感度限界による誤検知・検知漏れ

不活動検知・転倒検知は、端末に内蔵された加速度センサーの値をもとに判定しています。

検知漏れの例：端末がカバンや上着の中に入っていて動きを十分に拾えない／転倒したが端末は手から離れて動かなかった／不活動の判定しきい値より短い時間で「動いた」と認識される動きがあった
誤検知の例：端末を落とした・激しく振った・乗り物の急ブレーキの揺れを「転倒」と判定した

転倒検知については、誤検知を踏まえて「大丈夫ですか？」確認画面を 60 秒表示し、ご本人が「大丈夫です」と応答できる猶予を設けていますが、それでも防ぎきれない誤検知・検知漏れがあり得ます。

2-6. 利用者による設定誤り

本アプリには、利用者ご自身で調整いただける設定があります。設定によっては、検知・通知の挙動が変わります。

不活動アラートのしきい値（30 分〜48 時間）
夜間モードの開始時刻・終了時刻
各検知機能（不活動・転倒・位置情報）の ON/OFF トグル
通知種別ごとの ON/OFF（ガーディアン側）
役割（シニア／ガーディアン）の切り替え

たとえば、シニア側で「不活動検知 OFF」「位置情報 OFF」にすると、ガーディアン側に通知や位置情報が届かなくなります。本アプリは「設定を OFF にした」ことをガーディアン側にも表示しますが、設定の意味をご家族で共有しておくことを強くお勧めします。

2-7. 第三者サービスの障害

本アプリは、以下の外部サービスを利用しています。これらのサービス側で障害が発生した場合、本アプリの一部または全部の機能が停止することがあります。

Google Firebase（認証、データベース、通知配信）
携帯電話会社・インターネットプロバイダ

2-8. 不可抗力

地震・台風・大雪などの自然災害、戦争、テロ、大規模停電、その他、当社の支配下にない事由により、本サービスの全部または一部が利用できなくなることがあります。

2-9. 検知はリアルタイムではありません

本アプリは、リアルタイムの警報装置ではありません。

不活動の判定はサーバー側で約 15 分ごとに行われ、お客様が設定したしきい値（30 分〜48 時間）を経過してはじめて通知されます。しくみ上、実際の異変から通知まで数時間以上かかることがあります。
転倒の通知は、端末上の「大丈夫ですか？」確認（60 秒）などの手順を経たあとに送信されます。
通知の配信は Google のプッシュ通知基盤（Firebase Cloud Messaging）を利用しており、回線状況や受信側端末の省電力状態によって遅延することがあります。配信時間の保証はありません。

2-10. ご利用にあたってのお願い（利用者の皆さまにしていただくこと）

本アプリは、正しく設定・維持されてはじめて役に立ちます。次の事項は、シニアユーザーとご家族（ガーディアン）の皆さまご自身で行っていただく必要があります。

シニアの端末を充電し、電源を入れ、ご本人の身近に置いておくこと
端末をモバイル回線または Wi-Fi につないでおくこと
必要な権限・設定（センサー・位置情報・通知・バッテリー最適化の除外・メーカー独自の省電力設定の除外）を許可し、維持すること
利用したい検知機能を ON のままにし、各設定の意味を理解しておくこと
アプリ内の見守り稼働表示を定期的（毎日を推奨）に確認し、ガーディアン側の画面でシニアの活動状況が更新されていることを確認すること（週 1 回、および機種変更・OS アップデート・設定変更のあとを推奨）
本アプリに頼らない、日ごろの直接の連絡（電話・訪問など）と緊急時の連絡手段を維持すること

本アプリは、直接の連絡・介護・公的な緊急サービスの「代わり」には決してなりません。あくまで補助としてお使いください。

Disclaimer / Important Notice

Last updated: July 2, 2026
Effective: July 2, 2026 (Version 1.1)

This page explains, in plain language, what you need to know before relying on the Mimamori app. Mimamori helps families keep an eye on elderly relatives who live alone, but it cannot guarantee safety or life. Please read and accept what is described on this page before you use the App.

PLEASE READ THIS PAGE CAREFULLY. IT CONTAINS DISCLAIMERS OF WARRANTIES, AN EXPRESS ASSUMPTION OF RISK, LIMITATIONS OF LIABILITY, AND DISPUTE-RESOLUTION TERMS — INCLUDING A CLASS-ACTION WAIVER AND A ONE-YEAR TIME LIMIT FOR BRINGING CLAIMS, WHERE PERMITTED BY LAW — THAT AFFECT YOUR LEGAL RIGHTS.

⚠️ IMPORTANT: In an emergency, do not rely on the App alone. Please call the appropriate public emergency service for your location — in Japan dial 119, in EU countries dial 112, in the United States dial 911, in the United Kingdom dial 999, in Australia dial 000, and elsewhere please use your country's emergency number.

1. Introduction — What This App Is, and What It Is Not

Mimamori is software that helps families monitor their elderly relatives. Using the smartphone's built-in accelerometer, GPS, and other sensors, the App tries to detect inactivity, falls, and SOS events, and to notify a Guardian (a linked family member).

However, the App:

Is not a medical device. It is not designed for diagnosing, treating, or preventing any health condition, and it is not authorized as a medical device under any country's medical device regulations.
Is not an emergency-dispatch service. It is not directly connected to public emergency response infrastructure such as 119 / 112 / 911 / 999, and notifications from the App are sent only to the Guardian Users you have linked.
Is not a safety guarantee service. Installing the App does not guarantee that you will always notice a problem. As described below, detection and notification can be delayed or may not happen at all.
Is not a monitoring center. No person at the developer watches, reviews, or responds to your data or alerts. The Service is fully automated software: detections and notifications are generated and delivered by machines, without human review. We do not undertake any duty to observe any User, to detect any particular event, to deliver any particular notification, or to summon, dispatch, or provide help.

Please think of the App as a supplementary tool that improves the chance of noticing a problem, not as a guaranteed safety net.

Geographic scope. The Service is currently offered and directed solely to users located in Japan. We make no representation that the App is appropriate, lawful, or available for use in any other country, and we do not target or solicit users outside Japan. If you nevertheless install or use the App from outside Japan, you do so on your own initiative and at your own risk, and you are responsible for compliance with your local laws. This English text is provided for the convenience of English-speaking users located in Japan.

The App is intended for users aged 16 or older, and is to be used with the consent of the Senior User who is being monitored. If you are under the age of majority in your jurisdiction, you may use the App only with the involvement and consent of a parent or legal guardian. If you set up the App for, or accept the Terms of Service or this Disclaimer on behalf of, a Senior User, you represent and warrant that the Senior User consents to being monitored and that you have the authority to accept these documents on the Senior User's behalf (for example, with the Senior User's informed consent, or as the Senior User's legal representative); in that case, references to "you" include the Senior User.

2. Main Reasons Why Detection or Notification May Fail or Be Delayed

We cannot, in technical practice, guarantee perfect detection or delivery of notifications. Below are concrete examples of situations in which detection or notification may be delayed or may not happen at all.

2-1. Network failures and delays

Notifications travel from the Senior User's phone, through Google's cloud servers (Firebase), to the Guardian User's phone. If communications fail or are delayed anywhere along that path, notifications may not arrive — or may arrive late.

Example: the Senior User's home is in an area with poor mobile signal.
Example: the home Wi-Fi router malfunctions or is unplugged.
Example: a large-scale outage at the mobile carrier (the kind that affects a whole country once every few years).

2-2. Battery depletion, device powered off, or device failure

The App cannot operate if the device is off. If the battery is depleted, the device is switched off, or the device is broken, no detection or notification will occur.

The App includes a low-battery notification feature (the default threshold is 5%) to help Guardians notice before the battery is fully depleted. However, the device can run out of power before that notification arrives.

2-3. Operating-system enforcement and restrictions

Android may restrict the App's background activity to save battery or to keep the system stable.

Example: the "Battery optimization" feature restricts the App from running in the background.
Example: Android forcibly stops the App (e.g., under low-memory conditions).
Example: the user, or another app, executes "Force stop" on the App.
Example: some device manufacturers ship proprietary battery-saving or "app cleaning" functions that terminate background apps far more aggressively than standard Android — on some models, monitoring can stop even after the standard Battery Optimization exemption has been granted.

The App requests an exemption from Battery Optimization during first-run setup, but if this setting is not granted (or is later changed), operation can stop. Where your device has manufacturer-specific power-management settings, please also exempt the App there, and check the App's monitoring-status display regularly.

2-4. GPS accuracy limits and unavailability

Location is obtained from GPS satellites. In some places, accurate location cannot be obtained, or location data cannot be obtained at all.

Indoors (especially basements, reinforced concrete buildings, elevators)
High-rise urban areas (signal reflection introduces large errors)
Mountainous areas or tunnels
When the device is in airplane mode, or when location services are turned off

Also note: the location attached to an SOS or other alert is the most recently stored location, which may be up to about 15 minutes old (or older, if no newer location could be obtained). It may therefore differ from the User's actual location at the time of the event.

2-5. Sensor limitations leading to false positives or missed detections

Inactivity and fall detection are based on the values read from the device's accelerometer.

Missed detection examples: the device is in a bag or coat and cannot pick up motion well; the user fell, but the device became separated from the user and stopped moving on its own; activity within the inactivity threshold causes the system to consider the user "active."
False positive examples: the device was dropped or shaken hard; a vehicle's sudden braking shook the device and was classified as a fall.

For fall detection, to allow for false positives, the App shows an "Are you okay?" check for 60 seconds before alerting the family, giving the user time to dismiss the alarm. Even with this safeguard, false positives and missed detections cannot be fully eliminated.

2-6. User configuration mistakes

The App has settings that you can adjust. Depending on those settings, the App's detection and notification behavior changes.

Inactivity alert threshold (30 minutes to 48 hours)
Night-mode start and end times
On/off toggles for each detection feature (inactivity, fall, location)
Per-notification on/off settings for Guardians
Switching role (Senior / Guardian)

For example, if the Senior turns off "Inactivity detection" or "Location sharing," notifications and location data will no longer reach the Guardian. The App tries to show the Guardian that the Senior has turned a feature off, but we strongly recommend that families discuss the meaning of these settings together.

2-7. Outages of third-party services

The App relies on the following external services. If any of these services experiences an outage, some or all of the App's features may be unavailable.

Google Firebase (authentication, database, push notifications)
Mobile carriers and internet service providers

2-8. Force majeure

Earthquakes, typhoons, heavy snow, wars, terrorism, large-scale power outages, and any other events outside our reasonable control may cause all or part of the Service to become unavailable.

2-9. Detection is not real-time

The Service is not a real-time alarm system.

Inactivity is evaluated periodically on the server (approximately every 15 minutes) against the threshold you configure (30 minutes to 48 hours). By design, an inactivity alert arrives only after the configured period has elapsed — potentially many hours after the underlying event.
Fall alerts are sent only after the on-device confirmation window ("Are you okay?", 60 seconds) and any escalation steps have passed.
Notifications are delivered through Google's push-notification infrastructure (Firebase Cloud Messaging), which is a best-effort service: delivery can be delayed by the network or by the receiving device's power-saving state, and no delivery time is guaranteed.

2-10. Your responsibilities

The App can help only if it is set up and maintained correctly. The following are things that you — the Senior User and the Guardian Users, together as a family — are responsible for doing:

keeping the Senior User's device charged, powered on, and carried on or near the Senior User;
keeping the device connected to a working mobile or Wi-Fi network;
granting and maintaining the required permissions and settings (sensors, location, notifications, the Battery Optimization exemption, and any manufacturer-specific power-management exemptions);
keeping the detection features you rely on turned ON, and understanding what each setting does;
checking the App's monitoring-status display regularly (we recommend daily), and confirming on the Guardian's screen that the Senior User's activity status is updating (we recommend weekly, and after every device change, OS update, or settings change);
maintaining regular direct contact with the Senior User (calls, visits) and independent emergency arrangements that do not depend on the App.

The App is a supplement to — never a replacement for — direct human contact, caregiving, and professional emergency services.

3. How the App Is Provided, and Limitation of Liability

Building on the technical and service-level limitations described above, we set out below the basis on which the App is provided, and the scope of the developer's liability.

3-1. "AS IS" / "AS AVAILABLE" basis

THE APP IS PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE DEVELOPER (WATER INC.) AND ITS AFFILIATES, OFFICERS, EMPLOYEES, AGENTS, AND CONTRACTORS DISCLAIM ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING WITHOUT LIMITATION:

WARRANTIES OF MERCHANTABILITY
WARRANTIES OF FITNESS FOR A PARTICULAR PURPOSE
WARRANTIES OF ACCURACY, TIMELINESS, OR RELIABILITY OF DETECTION OR NOTIFICATIONS
WARRANTIES OF UNINTERRUPTED OR ERROR-FREE OPERATION
WARRANTIES OF NON-INFRINGEMENT
WARRANTIES ARISING FROM COURSE OF DEALING, COURSE OF PERFORMANCE, OR TRADE USAGE

NO ADVICE OR INFORMATION, WHETHER ORAL OR WRITTEN, OBTAINED FROM THE DEVELOPER OR THROUGH THE APP, SHALL CREATE ANY WARRANTY NOT EXPRESSLY STATED IN THIS DISCLAIMER.

THE DEVELOPER IS NOT AN INSURER. ANY FEES FOR THE SERVICE ARE NOT INSURANCE PREMIUMS: THEY ARE NOT RELATED TO THE VALUE OF THE SENIOR USER'S LIFE, HEALTH, OR PROPERTY, AND THEY DO NOT COMPENSATE THE DEVELOPER FOR ASSUMING ANY RISK OF LOSS. IF YOU WANT PROTECTION AGAINST SUCH LOSS, YOU SHOULD OBTAIN APPROPRIATE INSURANCE. THE DISCLAIMERS AND LIMITATIONS IN THIS DISCLAIMER AND IN SECTION 11 OF THE TERMS OF SERVICE REFLECT THIS ALLOCATION OF RISK, WHICH IS A PART OF THE BARGAIN BETWEEN YOU AND THE DEVELOPER AND IS REFLECTED IN THE PRICE (INCLUDING A FREE PRICE) OF THE SERVICE.

3-2. Not a medical device or emergency-dispatch service

The App is NONE of the following:

A medical device under any country's medical-device, drug, or health-product regulations (including but not limited to the U.S. Food, Drug, and Cosmetic Act; EU Medical Device Regulation (EU) 2017/745; Japan's Pharmaceuticals and Medical Devices Act; UK MHRA regulations)
An emergency-dispatch or 911 / 112 / 999 service, or any other public emergency-response infrastructure
A Personal Emergency Response System (PERS)
A substitute for professional medical, safety, or caregiving services

The App has not been reviewed, cleared, or approved by the U.S. Food and Drug Administration (FDA), by Japan's PMDA, or by any other medical-device regulator. It is offered as a general family-awareness aid and makes no medical, diagnostic, therapeutic, or preventive claims.

DO NOT USE THE APP FOR ANY MEDICAL DECISION, DIAGNOSIS, OR TREATMENT, OR AS YOUR PRIMARY MEANS OF SUMMONING EMERGENCY HELP.

3-3. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL THE DEVELOPER (WATER INC.) OR ITS AFFILIATES, OFFICERS, EMPLOYEES, AGENTS, OR CONTRACTORS BE LIABLE FOR ANY:

DIRECT, INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, PUNITIVE, OR EXEMPLARY DAMAGES
DAMAGES FOR PERSONAL INJURY, DEATH, OR LOSS OF LIFE
DAMAGES FOR EMOTIONAL DISTRESS OR MENTAL ANGUISH
DAMAGES FOR LOSS OF PROFITS, REVENUE, BUSINESS, DATA, USE, GOODWILL, OR OTHER INTANGIBLE LOSSES
DAMAGES FOR LOSS OR DAMAGE TO PROPERTY

ARISING OUT OF OR RELATED TO YOUR ACCESS TO, USE OF, OR INABILITY TO USE THE APP, OR YOUR RELIANCE ON ANY DETECTION OR NOTIFICATION (OR THE ABSENCE OR DELAY THEREOF), WHETHER BASED ON WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR ANY OTHER LEGAL THEORY, AND EVEN IF THE DEVELOPER HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

Where, despite the foregoing, the developer is found liable, the developer's aggregate liability is subject to the monetary cap set out in Section 11.3 of the Terms of Service (which is the legally binding limitation-of-liability provision).

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, YOUR SOLE AND EXCLUSIVE REMEDY FOR ANY DISSATISFACTION WITH THE APP, THE SERVICE, OR THIS DISCLAIMER IS TO STOP USING THE APP AND DELETE YOUR ACCOUNT (TOGETHER WITH ANY REFUND EXPRESSLY PROVIDED FOR BY THE STORE'S REFUND POLICY, FOR PAID PLANS).

To the fullest extent permitted by applicable law, the exclusions and limitations in this Section 3 and in Section 11 of the Terms of Service also apply to claims brought by or on behalf of a User's heirs, estate, executors, family members, successors, or assigns — including wrongful-death and survival claims — and each User accepts these provisions on their own behalf and, to the extent permitted, on behalf of those persons.

Mandatory-law carve-out. Some jurisdictions do not allow the exclusion or limitation of certain warranties or liabilities (for example, for personal injury caused by negligence, or for fraud or willful misconduct). In those jurisdictions, the exclusions and limitations above apply only to the extent permitted by applicable law, and the developer's liability is limited to the minimum permitted by law. In particular, under the Consumer Contract Act of Japan (Article 8, Paragraph 1), provisions that fully exclude the developer's liability for damages caused by the developer's willful misconduct or gross negligence are void; the provisions above are not intended to, and do not, exclude such liability. Notice to New Jersey residents: the exclusions and limitations in this Disclaimer are intended to apply to you only to the extent permitted by New Jersey law, and nothing in this Disclaimer limits or waives any right or remedy that New Jersey law does not permit to be limited or waived.

3-4. Assumption of risk

BY USING THE APP, YOU ACKNOWLEDGE AND AGREE THAT YOU HAVE READ AND UNDERSTOOD THE LIMITATIONS DESCRIBED IN THIS DISCLAIMER, THAT YOU USE THE APP AT YOUR OWN RISK AND AT YOUR OWN JUDGMENT, AND THAT YOU EXPRESSLY AND VOLUNTARILY ASSUME ALL RISKS ASSOCIATED WITH YOUR USE OF, AND RELIANCE ON, THE APP, INCLUDING WITHOUT LIMITATION THE RISKS THAT:

A FALL, A PERIOD OF INACTIVITY, AN SOS, OR ANY OTHER EVENT IS NOT DETECTED, OR IS DETECTED LATE;
A NOTIFICATION IS DELAYED, MISDELIVERED, OR NEVER DELIVERED;
LOCATION INFORMATION IS INACCURATE OR OUTDATED (INCLUDING UP TO ABOUT 15 MINUTES OLD, OR OLDER);
MONITORING STOPS OR DEGRADES BECAUSE OF DEVICE, BATTERY, NETWORK, OPERATING-SYSTEM, MANUFACTURER POWER-MANAGEMENT, CONFIGURATION, OR THIRD-PARTY SERVICE CONDITIONS;
FALSE ALARMS OCCUR; AND
INJURY, DEATH, OR PROPERTY DAMAGE OCCURS THAT MIGHT HAVE BEEN AVOIDED IF DETECTION OR NOTIFICATION HAD OCCURRED EARLIER OR AT ALL.

THIS EXPRESS ASSUMPTION OF RISK IS A MATERIAL PART OF THE BASIS ON WHICH THE DEVELOPER OFFERS THE APP. IT IS MADE BY EACH USER ON THEIR OWN BEHALF AND, TO THE EXTENT PERMITTED BY APPLICABLE LAW, ON BEHALF OF THE USER'S HEIRS, ESTATE, AND SUCCESSORS.

3-5. Indemnification

You agree to indemnify, defend, and hold harmless the developer (Water Inc.) and its affiliates, officers, employees, agents, and contractors from and against any and all third-party claims, damages, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or related to your misuse of the App, your violation of this Disclaimer or the Terms of Service, or your violation of any applicable law or the rights of any third party.

3-6. No duty to monitor; no special relationship

The developer provides automated software only. The developer does not operate a monitoring center, does not employ or engage any person to watch, review, or respond to Users' data or alerts, and does not undertake to protect the safety of any person. Nothing in the Service, this Disclaimer, or the Terms of Service creates any fiduciary, custodial, caregiving, bailment, or other special relationship between the developer and any User or monitored person, and the developer assumes no duty of care beyond the express commitments stated in the Terms of Service. No voluntary act by the developer (for example, answering a support inquiry) shall be construed as an undertaking to render protective services or as an assumption of any such duty.

3-7. Dispute resolution; class-action waiver; time limit for claims

(a) Talk to us first (mandatory informal resolution). If you have any concern, complaint, or claim, you agree to contact us first at water.inc.holdings@gmail.com (subject: "Mimamori — Dispute Notice") with a written description of the issue and the remedy you seek, and to try in good faith to resolve the matter with us informally for at least 60 days before starting any court or other formal proceeding. Most issues can be resolved this way, quickly and at no cost to you.
(b) Individual capacity only. To the fullest extent permitted by applicable law, any claim against the developer must be brought in your individual capacity only, and not as a plaintiff or member of a class in any purported class, collective, consolidated, or representative proceeding.
(c) Jury waiver. To the extent a dispute proceeds in a court that gives effect to pre-dispute jury-trial waivers, you and the developer each waive any right to a trial by jury. (This waiver does not apply where such waivers are not enforceable — for example, in California state courts.)
(d) Time limit for claims. To the fullest extent permitted by applicable law, any claim arising out of or relating to the App, the Service, or this Disclaimer must be filed within one (1) year after the claim accrues; claims not filed within that period are permanently barred. This limit does not apply where prohibited by mandatory law.
(e) Forum and governing law. Except where mandatory consumer-protection law of your place of residence provides otherwise, disputes are governed by Japanese law and are subject to the exclusive jurisdiction of the Tokyo District Court, as set out in Section 14 of the Terms of Service.

【弁護士判断・経営判断: Before any distribution of the App in the United States, add a binding individual-arbitration agreement to Section 14 of the Terms of Service (e.g., AAA Consumer Arbitration Rules or JAMS, with a small-claims carve-out, a 30-day opt-out right, mass-arbitration batching procedures, and a class-action waiver). Items (b)–(d) above are materially more enforceable inside such an arbitration agreement (AT&T Mobility v. Concepcion line) than standing alone.】

3-8. Relationship to the Terms of Service; survival

This Disclaimer forms part of the Terms of Service. The governing law (Japanese law), jurisdiction, and severability provisions of the Terms of Service (Sections 14 and 15) apply equally to this Disclaimer. If any provision of this Disclaimer is held invalid or unenforceable, the remaining provisions will continue in full force and effect. Sections 3-1 through 3-7 of this Disclaimer survive any deletion of your Account and any termination of the Terms of Service.

4. In an Emergency

We have said this above, but it is worth saying again: in an emergency, do not rely on the App alone.

For a life-threatening emergency:
- Japan: 119 (fire / ambulance)
- EU member states: 112 (single European emergency number)
- United States: 911
- United Kingdom: 999 (and 112 also works)
- Australia: 000
- In other countries, please use the appropriate emergency number for your location
For crime or accidents: please use your country's police number (e.g., Japan: 110; US: 911; UK: 101 non-emergency, 999 emergency)
For health advice: please contact your usual medical provider, or your country's health advice line

The App is a tool that increases the chance that families will notice a problem. The response after noticing depends on the family and the public services in your country.

5. Intentional Misuse

The App is designed to be used with the consent of the Senior User. The following uses are prohibited by the Terms of Service, and we cannot support them:

Tracking or monitoring a spouse, family member, or acquaintance without that person's consent
Stalking or any other conduct that threatens another person's freedom or safety
Workplace employee monitoring or movement tracking, or any other use outside the App's intended purpose

As a rule, linking happens when the Senior User actively creates an account and shares an invite code with their family. We cannot detect or prevent linking that occurs through stolen invite codes or against the Senior User's will. Please manage your invite code carefully and verify who you are linking with.

However, after the initial invite-code link has been established, co-managers (additional administrators) added by the representative Guardian via QR code, and — under the Facility Plan — facility staff, may also access the Senior User's data (location, audio, activity status, and so on) without the Senior User's separate, per-instance consent (see Privacy Policy §6.1 for details: https://sites.google.com/site/keicesoftjp/mimamori/mimamori_privacy). 【弁護士判断: Lawfulness of adding co-managers / facility staff without the Senior User's per-instance consent (APPI third-party provision vs joint use)】

Audio recordings. When an SOS is triggered, the App records about 10 seconds of ambient audio, which may capture the voices of people nearby. You are responsible for using the App — including its recording feature — in compliance with the laws that apply to you, including any laws that require the consent of the persons being recorded.

6. Please Use the App with an Understanding of Its Limits

As you have read, the App has many technical and service-level limitations. We have built it nonetheless, in the hope that it can help:

families who think, "If only we had noticed a bit earlier..."
families who think, "I worry about my distant parent, but calling every day is a burden..."
elderly users who think, "I live alone, but I don't want to worry my family..."

The App is a tool that increases the chance of noticing. It is not a safety guarantee. Detection may be delayed or may not happen at all. In an emergency, please do not rely on the App alone. We hope that families will discuss these limits together and use the App with that understanding.

7. Changes to this Disclaimer

We may amend this Disclaimer as needed. If we make a material change, we will give notice at least 30 days before the change takes effect, in the App or on the web. For material changes, we may ask you to consent again (for example, via the first-launch modal). The version and effective date of this Disclaimer are tracked in the header above and in the Revision History below.
