This is an English translation provided for convenience. The Korean version at ketoz.app/terms is the binding original; if the two differ, the Korean text prevails.

Article 1 (Purpose)

These Terms set out the rights, obligations and responsibilities of the individual or business operating Ketoz (the "Service"; the "Operator") and of its users, in relation to the use of the Service.

Article 2 (Definitions)

"Service" means the mobile application and all related features provided by the Operator, through which users can look up nutrition information such as net carbs by scanning a barcode or taking a photo, see guidance on whether a product fits a keto diet, record what they have eaten (the Keto Diary), submit product information through photos and other means, and use community features (likes and short comments).
"User" means anyone who uses the Service under these Terms.
"Z Points" ("Z") means an internal virtual metric provided within the Service as a reward for a user's activity in the Service (contributing photos, registering information, viewing ads and so on).

Article 3 (Effect and Amendment of these Terms)

These Terms take effect when posted on a Service screen or otherwise announced.
The Operator may amend these Terms to the extent permitted by applicable law, and will give advance notice of any amendment through in-app announcements or this page. Amended Terms take effect when posted.
A user who does not agree to the amended Terms may stop using the Service and withdraw by deleting the app. Continuing to use the Service after notice of an amendment is treated as acceptance of that amendment.

Article 4 (Provision and Modification of the Service)

The Service can be used without signing up, and users are distinguished by a unique identifier issued automatically per device. Linking an account (registering an email address) is optional.
The Operator may change all or part of the Service as required by the content of the Service or by operational and technical needs.
The nutrition information, net carb calculations and keto suitability ratings provided by the Service are for reference only and are not a substitute for medical or nutritional diagnosis or prescription. Please consult a professional if you need supervised dietary management.
The nutrition information you see is collected and generated through various routes, including manufacturer labelling, user submissions and automatic AI recognition, and the Operator does not guarantee that it is complete or accurate. If you find an error, please report it through the in-app reporting feature and it will be reviewed and corrected.
The product database is built mainly from products sold in South Korea and Japan. Products from other markets may not be found, and product names and ingredient lists are stored in their original language.

Article 5 (Restriction and Suspension of the Service)

The Operator may temporarily suspend the Service for reasons of force majeure such as equipment inspection and maintenance, natural disasters or a surge in traffic, or where operationally or technically necessary.
The Operator may permanently discontinue the Service where unavoidable, and in that case will make reasonable efforts to give advance notice through in-app announcements.
The Service is a small service run by a single operator and is not guaranteed to be available continuously without interruption.

Article 6 (User Obligations)

Users must not do any of the following.

Register or submit false information (product names, nutrition information, photos and so on).
Post content that infringes the rights of others, such as copyright or likeness rights.
Post inappropriate content in short comments or elsewhere, including abuse, defamation, obscenity or advertising spam.
Upload photos unrelated to product information (nutrition labels, product fronts and the like) as submissions. In particular, please never upload photos showing your own or another person's face or body, photos containing personal or financial information such as identity documents or cards, or photos containing information that can identify a specific person such as an address or vehicle number plate. Submitted photos are reviewed by the Operator, so please take particular care not to upload photos containing personal information unrelated to the product.
Accumulate Z or abuse Service features by improper means, such as creating multiple accounts or using automation tools (bots).
Interfere with the normal operation of the Service or place an excessive load on its servers or network.
Otherwise act in breach of applicable law or these Terms.

Article 7 (User Content and Restriction Measures)

Rights in content registered by a user, such as photos and short comments, belong in principle to that user, but the Operator may use that content to the extent necessary to provide, operate and promote the Service.
The Operator may delete content that breaches Article 6 without prior notice, either on receiving a user report or at its own discretion.
The Operator may restrict a user's use of the Service (accruing Z, registering content and so on) where that user repeatedly breaches Article 6 or seriously impairs the operation of the Service.

Article 8 (Z Points)

Details concerning Z are governed by the Privacy Policy. The key points are as follows.

Z is not cash, a deposit, a gift certificate, a security or any comparable financial product, and cannot be exchanged for cash, sold, transferred or lent.
Places where Z can be spent (such as partner shops) are in preparation. Whether, when and on what conditions they launch may change at the Operator's business discretion, and they may not launch at all.
If the Service is discontinued, any Z balance held by a user will be forfeited, and the Operator has no obligation to refund or compensate for it.
Z accrued by improper means may be adjusted or reclaimed without prior notice.

Article 9 (Disclaimer)

The Operator is released from responsibility for providing the Service where it cannot do so because of a natural disaster or comparable force majeure.
The Operator is not responsible for a user failing to obtain the results they hoped for from the Service, such as health management outcomes.
The Operator is not responsible for damage arising from errors in nutrition information published in the Service, except where the Operator has acted with intent or gross negligence.
The Operator is not responsible in connection with the use of the Service provided free of charge, except where applicable law specifically provides otherwise.
