Nomicho Terms of Service

Operator: Chris Hashimoto (橋本クリス), sole proprietor (個人事業主) Trade name: Nomicho (飲み帳) Address: Disclosed without delay upon request (contact support@nomicho.jp) Contact: support@nomicho.jp Effective date: 2026-06-11 Last updated: 2026-06-11 (v1.0)

1. Introduction

These Terms of Service (“Terms”) govern your use of the Nomicho mobile application (the “App”). Nomicho is operated by Chris Hashimoto, a sole proprietor in Japan (“we”, “us”). By using the App, you agree to these Terms. If you do not agree, please do not use the App.

2. Eligibility

The App is intended for adults in Japan aged 20 or older — the legal drinking age. As part of accepting these Terms on first launch, you affirm that you are 20 or older. Users under 20 must not use the App.

If we learn that an account is being used by a person under 20, we may suspend or terminate access to that account.

3. Account and sign-in

3.1 Use without an account

The App can be used entirely without an account. All core features (logging, BAC estimation, calendar, journal, AI features) work locally on your device.

3.2 Optional sign-in

Sign-in is required only if you want cloud sync across devices. Sign-in is provided through Sign in with Apple, Google, or LINE. The handling of account information is described in our Privacy Policy §2.2.

3.3 Your responsibility for your sign-in environment

You are responsible for maintaining the security of the device and the third-party account (Apple, Google, or LINE) used to sign in to the App. We are not responsible for losses arising from unauthorized access to those upstream accounts. If you suspect unauthorized access, sign out from the App on the affected device and revoke its access from your Apple, Google, or LINE account.

4. What the App is, and what it is not

4.1 What the App provides

Nomicho is a personal journal and prediction tool for your own drinking. It helps you:

• Log what you drank, when, and how you felt.
• Look back through a calendar, journal, and statistics, and read AI-generated reflection cards of your nights.
• See real-time, in-session estimates of your blood alcohol concentration (BAC), state-of-intoxication transitions, threshold warnings, and a hangover forecast.

4.2 What the App is not

The App is not:

• a medical device, diagnostic tool, or treatment;
• a substitute for advice from a physician or other qualified professional;
• a legal-grade alcohol breath analyzer, breathalyzer, or any other instrument suitable for legal, regulatory, employment, or insurance purposes;
• a guarantee that you are safe to drive, operate machinery, return to work, or perform any other activity.

The App makes no medical or health claims. It does not diagnose, treat, predict, or monitor any medical condition, including alcohol intoxication, alcohol use disorder, or any of their effects on the body. The hangover forecast is a non-medical, heuristic estimate of how you might subjectively feel the next day — not a medical prediction or measurement of a bodily condition.

4.3 BAC estimate disclaimer

The BAC value, intoxication-state transitions, threshold warnings, and hangover forecast shown in the App are statistical estimates based on inputs you provide (drinks, body weight, sex, time) and are subject to wide individual variation. They are not measurements.

The estimates depend on the accuracy of the drink details you record (type, volume, and ABV, including any details looked up automatically). Errors in those inputs propagate to all downstream estimates, including state transitions, threshold warnings, and the hangover forecast.

You must not use these estimates to decide whether to drive, operate machinery, or do anything else where being under the influence of alcohol could harm you or another person.

The only safe blood alcohol concentration for driving in Japan is 0. Regardless of what the App shows, driving while under the influence of alcohol — both 酒気帯び運転 and 酒酔い運転 — is prohibited under the Road Traffic Act (道路交通法) and is subject to criminal penalties.

5. AI features

The App uses AI (provided by Anthropic) to generate reflection cards from your session data. AI-generated outputs are statistical and may be wrong, incomplete, biased, or unsafe. Treat them as suggestions, not facts.

The data flow, storage, and retention for AI calls are described in the Privacy Policy §5.1.

You must not rely on AI-generated content for medical, legal, financial, or safety-critical decisions.

6. Your content

“Your content” means the drink logs, notes, feeling tags, and other material you create through the App.

6.1 You retain rights

You retain all rights in your content. We do not claim ownership.

6.2 License you grant us

To operate the App, you grant us a limited, non-exclusive, royalty-free, worldwide license to your content only to the extent necessary to:

• store it on your device;
• process it on your device for App features (logging, BAC estimation, journal, calendar);
• transmit it to and store it in our cloud infrastructure if and only if you enable sync (see Privacy Policy §4.2);
• send relevant content to AI providers when you invoke an AI feature (see Privacy Policy §5.1);
• back up and restore your data within the bounds of normal service operation.

This license is limited to delivering the App’s features to you. It does not authorize us to use your content for AI model training, advertising, marketing, public display, sale, or any other purpose.

6.3 License termination

The license terminates when you delete the relevant content or your account. Cloud copies are deleted on the timeline described in the Privacy Policy §6.

6.4 Your responsibility for content you upload

You represent that you have the right to the content you create (for example, menu names or brand names you enter) and that doing so does not violate the rights of others or the law. You are responsible for the content you create through the App.

7. Acceptable use

You agree not to:

• reverse engineer, decompile, or disassemble the App, except to the extent expressly permitted by applicable law;
• attempt to bypass, defeat, or interfere with rate limits, daily caps, device attestation (App Attest on iOS), or other technical protections;
• access the App’s backend services other than through the App itself, or attempt to do so;
• use the App via automation, scraping, or scripted clients;
• use the App to harass, defame, or infringe the rights of others;
• use the App for any illegal purpose or in violation of any law applicable to you;
• impersonate another person or misrepresent your relationship to another person;
• attempt to disrupt the App, our infrastructure, or other users;
• resell, redistribute, or sublicense access to the App.

If we believe you are violating this section, we may suspend or terminate your access without prior notice where necessary to protect the service or other users.

8. Anti-social forces

By using the App, you represent and warrant that you are not, and are not acting on behalf of, an organized crime group (暴力団), a current member of an organized crime group (暴力団員), a former member of an organized crime group (within five years of leaving), an associate member of an organized crime group (暴力団準構成員), an entity affiliated with an organized crime group (暴力団関係企業), a corporate racketeer (総会屋), a person engaged in racketeering under the guise of social or political activism (社会運動等標榜ゴロ), a specialized-intelligence violence group (特殊知能暴力集団), or any other equivalent anti-social force, and that you have no close relationship with any of the foregoing.

If you breach this representation, we may suspend or terminate your access to the App immediately and without prior notice. We are not liable for any loss arising from such suspension or termination.

9. Fees

Core features are free to use. We also offer an optional paid subscription, Nomicho Plus. Its price and terms are shown to you before purchase, billing is handled by the App Store through your Apple ID, and you are not charged for any feature you have not purchased. You can cancel anytime from your App Store subscription settings. The annual plan includes a 7-day free trial; at the end of the trial it automatically converts to the paid annual subscription unless you cancel beforehand. The trial terms are shown before purchase and in the 特定商取引法に基づく表記.

For the paid subscription, the disclosures required of mail-order businesses under Japan’s Act on Specified Commercial Transactions (特定商取引法) are provided separately as our 特定商取引法に基づく表記, available in the App and on our website.

10. Privacy

We handle your personal information as described in our Privacy Policy. The Privacy Policy is part of these Terms. Please read it.

11. Disclaimers and limitation of liability

11.1 No warranty

The App is provided “as is” and “as available”. To the maximum extent permitted by law, we disclaim all warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, reliability, non-infringement, and uninterrupted or error-free operation.

In particular, we do not warrant that:

• BAC estimates, intoxication-state transitions, threshold warnings, hangover forecasts, AI outputs, or any other content shown in the App are accurate, complete, or fit for any specific use;
• the App will be available without interruption, free of bugs, or compatible with future versions of operating systems or devices.

11.2 No liability for drinking-related outcomes

To the maximum extent permitted by law, we are not liable for:

• any health, medical, physical, or psychological outcome related to your drinking, including hangovers, intoxication, alcohol poisoning, dependency, or chronic-disease risk;
• any decision you make about whether to drive, operate machinery, return to work, take medication, or undertake any other activity, including any decision influenced by the App’s BAC estimate or any other content;
• any criminal, civil, or administrative consequence (including under the Road Traffic Act) arising from your decisions about alcohol;
• any missed transportation (including missed last trains), or any harm arising from acting on a transportation-related notification (including last-train alerts);
• any financial, employment, relationship, or reputational outcome related to your drinking.

You are solely responsible for your own drinking decisions and for the consequences of those decisions, including any harm caused to third parties by those decisions, even where the decision was influenced by the App.

11.3 Limitation of liability

To the maximum extent permitted by law, our aggregate liability to you arising out of or relating to the App or these Terms is limited to the greater of (a) the total amount you have paid us for the App in the twelve months preceding the event giving rise to the claim, or (b) JPY 3,000.

We are not liable for indirect, incidental, special, consequential, or punitive damages, or for loss of profits, data, goodwill, or other intangible losses.

11.4 Mandatory-law carve-out

Nothing in §11.1, §11.2, or §11.3 limits or excludes:

• liability for damage to the life or body of a consumer caused by our negligence (whether light or gross);
• liability for damage caused by our intent or gross negligence; or
• any other liability that, under Japan’s Consumer Contract Act (消費者契約法 Article 8 and Article 8-2) or other mandatory law, cannot be excluded or limited by contract.

12. Changes to or discontinuation of the App

We may add, change, suspend, or discontinue features of the App at any time. Where a change materially reduces functionality you rely on, we will give reasonable advance notice in the App.

We may discontinue the App altogether. If we do, we will give at least 30 days’ advance notice in the App and, where you have enabled sync, by email. During that notice period, you will be able to export your data via Settings → Export Data.

13. Termination and account deletion

13.1 By you

You can stop using the App at any time. If you have an account, you can delete it via Settings → Delete Account. The data lifecycle following deletion is described in the Privacy Policy §6.

You can also export all of your data as JSON via Settings → Export Data at any time before deletion.

13.2 By us

We may suspend or terminate your access to the App if you materially breach these Terms (in particular §3.3, §6.4, §7, or §8), if required by law, or to protect the service or other users. Where it is reasonable to do so, we will give you advance notice and an opportunity to cure.

13.3 Effect of termination

Sections that by their nature are intended to survive termination — including §6.4, §7 (in respect of past acts), §10, §11, §15, §16, §17, §19, and any accrued rights and obligations — survive termination of these Terms.

14. Changes to these Terms

We may revise these Terms when the law changes, when we add or change features, or when our operations change. Where the change is a unilateral amendment to a standard-form contract, we will follow the procedures of the Civil Code (民法) Articles 548-2 through 548-4 governing standard-form contracts (定型約款).

The substance of any unilateral amendment will be limited to what is reasonable in light of the necessity of the change, the appropriateness of the post-amendment content, and the substance of the change, in accordance with 民法 Article 548-4.

For material changes, we will give at least 30 days’ advance notice through an in-App notification and, where you have enabled sync, by email. The notice will identify the effective date and the substance of the change.

If you continue to use the App on or after the effective date of a change, you accept the revised Terms. If you do not accept them, please stop using the App and, if applicable, delete your account before the effective date.

The revision history is in §20.

15. Severability

If any provision of these Terms is held to be invalid, illegal, or unenforceable, that provision is severed from these Terms and the remaining provisions remain in full force and effect.

16. Assignment

You may not assign or transfer any of your rights or obligations under these Terms without our prior written consent.

We may assign or transfer these Terms — including all of our rights and obligations under them — to a successor entity that takes over the operation of the App, including in connection with the incorporation of the operator’s business as a kabushiki-kaisha (株式会社), a merger, a corporate split, or other corporate restructuring, or a business transfer (事業譲渡). Any such assignment is limited to a transfer in connection with the business operating the App and will not worsen the terms applicable to you; you agree in advance to such an assignment or transfer, and you remain free to stop using the App and export your data under §13 if you do not wish to continue under the successor.

Any successor is bound by the Privacy Policy in effect at the time of transfer. Any subsequent change by the successor is subject to §14.

17. Governing law and jurisdiction

These Terms are governed by the laws of Japan, without regard to its conflict-of-laws rules.

Depending on the value of the claim, the Tokyo Summary Court (東京簡易裁判所) or the Tokyo District Court (東京地方裁判所) has exclusive jurisdiction as the court of first instance over any dispute arising out of or relating to these Terms or the App.

Where you are a consumer, this clause is subject to the protections of the Consumer Contract Act (消費者契約法) and Code of Civil Procedure (民事訴訟法), including any mandatory venue rules that cannot be displaced by agreement.

18. Contact

For questions about these Terms or the App:

• Email: support@nomicho.jp
• Operator: Chris Hashimoto (橋本クリス), sole proprietor

We will respond within a reasonable period (typically within two weeks).

19. Apple App Store terms

Because the App is distributed through the Apple App Store, the following terms apply. In the event of any conflict with the rest of these Terms as to your relationship with Apple Inc. (“Apple”), these terms govern:

• These Terms are concluded between you and us (the operator) only, not with Apple. We — not Apple — are solely responsible for the App and its content.
• Your licence to use the App is a non-transferable licence to use it on any Apple-branded device you own or control, as permitted by the App Store Terms of Service.
• Apple has no obligation to furnish any maintenance or support services for the App.
• To the maximum extent permitted by law, Apple gives no warranty for the App. If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) you paid for it; to the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App.
• We, not Apple, are responsible for addressing any claims by you or a third party relating to the App or your use of it — including product-liability, consumer-protection, and intellectual-property claims — to the extent required by these Terms and applicable law.
• You represent that you are not located in a country subject to a U.S. Government embargo or designated by the U.S. Government as a “terrorist supporting” country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
• Apple and Apple’s subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance Apple has the right (and is deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.
