Terms of Use

EightScan (찍먹체질) · Effective November 3, 2026 · Version 1.0

1. About these terms

These terms set out how you may use EightScan (the "app"), provided by Jinjo Labs Ltd. ("we"), and the rights and duties of both of us.

2. Agreement

By using the app you agree to these terms and to our Privacy Policy. Both are always available in the app and on this site.

3. What the app does

The app finds a food's ingredients from its barcode or a photo of its ingredient label, and shows on a five-level scale how well each ingredient, and the product overall, suits the Eight Constitution you chose. Product information comes from open data such as Food Safety Korea (Ministry of Food and Drug Safety) and Open Food Facts.

4. The nature of constitution information

  1. The verdicts are reference information based on an Eight Constitution food table. The app doesn't determine your constitution; you choose the one you already know.
  2. Verdicts are not medical advice and don't replace a doctor's judgment or care. If you have a medical condition or plan a major change to your diet, talk to a doctor first.
  3. Allergen information is shown exactly as the source gives it and never affects a verdict. If you have allergies, always check the label on the package.

5. Accuracy of product information

Product information and ingredients come automatically from open data and label photos, so they can be missing or wrong and may not reflect recent product changes. You can check and correct the text read from a label photo before it's rated. Check the package itself before making important decisions.

6. Free use and EightScan Pro

  1. Free: scanning, verdicts, scan history, label photo reading and the food list for your own constitution have no usage limits.
  2. EightScan Pro: family profiles (up to 6, including you) with side-by-side verdicts, and food lists for every constitution. Pro is a monthly or annual auto-renewing subscription; prices are shown in the app before you buy.
  3. Billing and renewal: subscriptions are sold by Apple (App Store) or Google (Google Play) and charged to your store account. A subscription renews automatically on the same terms unless you turn off auto-renew in your store account settings at least 24 hours before the current period ends. If you cancel, you keep Pro until the end of the period you've paid for.
  4. When a subscription ends: family profiles are kept, locked, never deleted, and come back when you subscribe again.
  5. Restoring: there are no accounts, so after reinstalling or on a new device, use "Restore purchases" in Settings to restore the subscription from the same store account.
  6. Refunds: Apple or Google handle refunds under their own policies. Nothing in these terms limits your statutory rights, such as cancellation rights under applicable law.
  7. Offer codes: subscription codes are redeemed in the app store and follow the store's terms.
  8. Price changes: we'll tell you before a new price applies. Where the store asks for your consent to a price increase, the subscription won't renew at the new price without it.

7. Your data

Your constitution, profiles, scan history and entered ingredients are stored only on your device; we don't back them up. Deleting the app deletes them permanently.

8. Our rights

The app, its design and software belong to us or their rightful owners. We give you a personal, non-commercial right to use the app under these terms. Data sources and their licenses are listed in the app under "Data sources & licenses".

9. Your obligations

Don't use the app unlawfully, overload our servers, decompile or tamper with the app, or harvest its data in bulk.

10. Changes to the app

We may change features to improve the app. We'll give notice before changes that disadvantage Pro subscribers or before shutting the app down, and handle periods already paid for under applicable law and store policies.

11. Limitation of liability

  1. We provide the app with reasonable care but don't guarantee that verdicts or product information are accurate or that the app is always available.
  2. Nothing in these terms limits liability that can't be limited by law, such as for our intent or gross negligence, or your rights under the consumer protection laws of the country where you live.

12. Apple and Google

These terms are between you and us, not Apple or Google. We, not Apple or Google, are responsible for the app, its content, maintenance and support. If you downloaded the app from the App Store:

  1. your right to use the app is limited to Apple devices you own or control, as permitted by the App Store usage rules;
  2. if the app fails to meet any applicable warranty, you may notify Apple, which will refund any purchase price for the app; Apple has no other warranty obligation for the app;
  3. we, not Apple, handle claims about the app, including product liability, legal or regulatory requirements, and consumer or privacy law;
  4. we, not Apple, are responsible for investigating and resolving claims that the app infringes third-party intellectual property;
  5. you must comply with the App Store usage rules and the terms of third-party services you use with the app;
  6. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you.

13. Changes to these terms

We'll announce changes in the app at least 30 days before they take effect and explain what changes and why. If you don't agree, you can turn off auto-renew in your store account settings before the effective date and stop using the app at no cost.

14. Governing law

These terms are governed by the laws of British Columbia and the federal laws of Canada that apply there, and disputes are resolved in the courts of British Columbia. If you live in South Korea, the mandatory provisions of Korean consumer protection law still apply to you, and you keep the right to bring a claim in a Korean court.

15. General

  1. If any part of these terms is invalid, the rest remains in effect.
  2. These terms and the Privacy Policy are the whole agreement between you and us about the app.
  3. These terms are also available in Korean. If the versions differ, the English version prevails, unless the law where you live allows you to rely on another version.
