Effective date: May 30, 2026 · Last revised: September 16, 2026
This is an English translation of the Korean Terms of Service, which prevail if the two differ.
Article 1 (Purpose)
These Terms set out the conditions and procedures for using the mobile app “Jann” (잔) (the “Service”), and the rights, obligations, and responsibilities of the Service operator (the “Company”) and users.
Article 2 (The Service)
The Company provides the following:
AI-based ingredient recognition and inventory management (fridge ingredients and expiry dates)
AI-based recipe generation and recommendations
Pairing recommendations based on which ingredients are used together in recipe data
Expiry reminders and weekly summary notifications
Search links to external shopping sites (Coupang, Kurly) for missing ingredients
Other additional services determined by the Company
Article 3 (Access and Accounts)
You can use the Service by signing in with Apple ID, Google, or Kakao, or without signing in via “Browse without signing in”.
Children under 14 may not use the Service.
Members are responsible for keeping their account information secure.
Article 4 (AI-Generated Content)
AI features are provided only if you agree to “Use AI features”.
AI-generated recipes and ingredient recognition results are for reference only. You are responsible for checking allergens, dietary restrictions, and food safety yourself.
The Company does not guarantee the accuracy or safety of AI-generated results.
Article 5 (Paid Services)
All features of the Service are currently free. AI features have monthly free usage limits to control costs (currently 15 AI recipe generations and 30 AI photo recognitions per month). Limits reset every month, and the app shows how many uses remain.
The Company may offer paid features in the future. If so, pricing, payment method, auto-renewal, and cancellation terms will be announced separately in advance.
If paid features are offered, payment will be made through the Apple App Store, and refunds will follow Apple App Store policy.
Article 6 (Advertising)
To keep the Service free, banner and interstitial ads may be shown in the app.
Ads are served through Google AdMob as non-personalized ads only, and the Company does not track users across apps for advertising.
Article 7 (External Links)
The Service may provide search links to external shopping sites so you can look for missing ingredients.
Purchases, payment, delivery, and refunds on external sites are transactions between you and that site, governed by its own terms and policies.
Article 8 (Prohibited Conduct)
You must not:
Interfere with the normal operation of the Service (including reverse engineering or tampering, abnormal access by automated means, or circumventing AI usage limits)
Collect or use other people’s personal information or accounts without authorization
Engage in any conduct that violates applicable law
Article 9 (Intellectual Property)
Rights in the Service and related software belong to the Company, excluding open-source components (see Open Source Licenses). (Korea Copyright Commission registration C-2026-023193)
Rights in user content, such as the fridge ingredients you record and recipes you save, belong to you.
Article 10 (Changes to and Suspension of the Service)
The Company may change or suspend part or all of the Service for operational or technical reasons.
Material changes will be announced in advance.
Article 11 (Account Deletion and Data)
Members may delete their account at any time in the app under “Me → Delete account”. Deletion removes the account and the user data stored on the device, and it cannot be restored.
User data such as fridge ingredients, saved recipes, and photos is stored on your device, and the Company does not provide server backups. Signing out or deleting the app may delete the data on your device.
Article 12 (Limitation of Liability)
The Company is not liable for damage caused by natural disasters, force majeure, or reasons attributable to the user.
The Company is not liable for temporary service interruptions caused by outages of third-party services such as Apple, Google, Kakao, OpenAI, or Cloudflare, except for damage caused by the Company’s intent or gross negligence. Nothing in these Terms limits liability that cannot be limited under the mandatory consumer-protection law of your country of residence.
Article 13 (Changes to These Terms)
The Company may amend these Terms within the limits of applicable law, and will announce the effective date and reason for any change in advance, such as through an in-app notice.
Article 14 (Dispute Resolution)
Matters not covered by these Terms are governed by the laws of the Republic of Korea and general commercial practice. Disputes relating to the Service will be resolved in the court with jurisdiction under the Korean Civil Procedure Act, without prejudice to any right you have as a consumer to bring proceedings in your country of residence.
