Article 1 (Application)

These Terms of Service (the “Agreement”) govern the relationship between HOKKALON Inc. (the “Company”) and users (“Users”) of the mobile application “あと何kcal / How many kcal can you still have” (the “App”). This Agreement is concluded solely between the Company and Users; Apple Inc. and Google LLC are not parties to it. The Company alone is responsible for the App and its content.

Article 2 (Getting Started)

The App does not require account creation or sign-in. It can be used immediately after installation.
Meal records, weight entries, and other user-entered data are stored locally on the device by default. See the Privacy Policy for details.

Article 3 (Prohibited Conduct)

Users must not:

Violate any laws, regulations, or public order and morals;
Infringe intellectual property, privacy, or other rights of the Company, other users, or third parties;
Reverse engineer, decompile, or disassemble the App;
Interfere with the service, including excessive automated access or unauthorized use of the API;
Provide false information or impersonate another person;
Engage in any other conduct deemed inappropriate by the Company.

Article 4 (Subscriptions and Billing)

“あと何kcal Pro” is an auto-renewing subscription. It renews automatically unless canceled at least 24 hours before the next billing date.
All billing, cancellation, and refund processes are handled by the respective app stores (App Store / Google Play). The Company does not process refunds within the App.
The features included in Pro (such as the number of AI calorie estimations or supported widgets) may be changed at the Company’s discretion to improve the service.
Users may restore purchases on another device or after reinstallation via the “Restore” function provided by the App.

Article 5 (AI-Generated Content and Disclaimers)

The “AI Calorie Estimation” feature uses an AI model to estimate calories (kcal) based on the meal description entered by the user. All estimates are for reference only; the Company does not guarantee their accuracy, completeness, or suitability.

5-1. Nutrition and Health Information

All values shown in the App — including AI-generated calorie estimates, remaining-calorie figures, and trend charts — are estimates. The App is not a substitute for professional medical or nutritional advice. Users with conditions such as diabetes, kidney disease, eating disorders, or any dietary restrictions must consult a qualified healthcare professional and not rely solely on the values shown in the App.

5-2. Allergens and Food Safety

The App does not assess allergens or the safety of foods. Users with food allergies or intolerances must verify ingredient labels themselves. The Company bears no liability for any health impact arising from reliance on AI-generated estimates.

5-3. Dieting and Weight Management

The App is intended to make daily calorie balance visible. It does not guarantee any specific health or weight-loss outcome and does not encourage extreme calorie restriction.

Article 6 (Suspension and Modification)

The Company may suspend or modify all or part of the App without prior notice due to maintenance, force majeure, or failures of external services (Cloudflare, OpenAI, App Store, Google Play, RevenueCat, etc.). The Company is not liable for resulting damages except in cases of willful misconduct or gross negligence.

Article 7 (Disclaimer)

The Company does not warrant that the App will meet particular purposes or operate without errors or interruption.
Except in cases of willful misconduct or gross negligence, the Company bears no liability for damages arising from the use of the App.
Maintenance and support obligations rest solely with the Company; Apple and Google bear no responsibility.

Article 8 (Data Deletion)

Because data is stored locally, Users may delete all records by uninstalling the App or by using the “Delete data” option in the settings screen. For information about data retained server-side, see the Privacy Policy.

Article 9 (Intellectual Property)

All intellectual property rights in the App and its associated source code, design, logo, and text belong to the Company or other rightful owners. Users must not reproduce, modify, or redistribute these without permission.

Article 10 (Changes to the Agreement)

The Company may revise this Agreement as needed. Material changes will be announced via in-app notifications or on this website. Continued use of the App after such changes constitutes acceptance of the revised Agreement.

Article 11 (Governing Law and Jurisdiction)

This Agreement is governed by the laws of Japan. The Sapporo District Court shall have exclusive jurisdiction over the first instance of any disputes arising in connection with the App.
