Privacy Policy
EightScan (찍먹체질) · Effective November 3, 2026 · Version 1.0
Jinjo Labs Ltd. ("we") runs EightScan, an app that reads food barcodes and ingredient labels and shows how well the ingredients suit the Eight Constitution the user chooses. This policy explains what information we handle and why, who handles it for us, how long it is kept, and your rights.
At a glance
- There are no accounts. We don't ask for your name, email or phone number.
- Your constitution, profile names, scan history and any ingredients you enter stay on your device and are never sent to us.
- To find a product we send its barcode number; to read an ingredient label we send the photo of the label. Photos are discarded as soon as they're read and are never stored.
- No ads, analytics or tracking.
1. Why we handle information
Only to:
- find product information and ingredients for a barcode;
- read the ingredient list from a label photo;
- check EightScan Pro subscriptions and restore purchases;
- keep the service reliable and secure (fixing errors, stopping abuse);
- answer your questions and meet legal obligations.
We never sell information or use it for advertising.
2. What we handle
Kept only on your device (we never receive it): your chosen constitution, profile names and constitutions, scan history, ingredients you entered or checked, and your language setting. Deleting the app deletes them.
| What | Items | Sent to | When |
|---|---|---|---|
| Product lookup | Barcode number, IP address | Our server (AWS Seoul region), Open Food Facts | When you scan a barcode (products already on your device aren't sent) |
| Label reading | The label photo (resized to 1600 pixels on the long side), IP address | Our server, Upstage Co., Ltd. | When you use label photo reading |
| Subscription | An anonymous purchaser ID created on your device, purchase history and subscription status | Apple, RevenueCat | When you buy, renew, redeem a code or restore |
The app asks you to frame only the ingredient label, but anything else in the picture is sent too, so please take care when photographing. Payments are processed by Apple or Google; we never receive payment details.
3. How long we keep it
- Label photos: discarded as soon as they're read. The app also deletes the photo from your device right after reading it.
- Server logs: our server doesn't record IP addresses. Logs hold only the barcode number and the outcome, and are deleted after 30 days.
- Product cache: product information (names, ingredients) isn't personal information; it's kept up to 30 days for later lookups.
- Subscriptions: RevenueCat keeps purchase records while needed to check and restore subscriptions; we'll help delete them on request.
4. Deletion
Information past its retention period is deleted without delay in a way that can't be recovered. Information on your device is deleted with the app.
5. Sharing
We don't share your information with third parties. To find products, the app looks barcodes up directly in Open Food Facts (an open food database), which receives the barcode number and your IP address.
6. Service providers
| Provider | Task |
|---|---|
| Amazon Web Services, Inc. | Running our server (Seoul region) |
| Upstage Co., Ltd. | Reading the ingredient list from label photos |
| RevenueCat, Inc. | Checking subscriptions and restoring purchases |
7. International transfers
| Recipient (contact) | Country | Items | Purpose |
|---|---|---|---|
| Upstage Co., Ltd. (infosec@upstage.ai) | South Korea, United States | Label photos, IP address | Reading ingredient lists |
| RevenueCat, Inc. (compliance@revenuecat.com) | United States | Anonymous purchaser ID, purchase history | Managing subscriptions |
| Open Food Facts (contact@openfoodfacts.org) | France | Barcode number, IP address | Product lookup |
Transfers happen over encrypted connections each time you use the feature, and retention follows section 3. Information held abroad is subject to that country's laws. You can avoid a transfer by not using the feature: no label photos are sent unless you use label reading, and no purchase information unless you subscribe.
8. Your rights
You can ask to access, correct, delete or stop the processing of your information at any time. Information on your device can be changed in the app or deleted with the app. We don't keep information that identifies you, so for server logs or subscription records please contact us (section 9).

10. Security
Everything is sent encrypted, server access is limited to the people who need it, and secrets such as API keys never ship in the app; they live only in our server's secret store.
11. Cookies and tracking
We don't use cookies, advertising identifiers, analytics or tracking technologies.
12. Children
Family profiles can include a child's name and constitution, but they stay on your device and are never sent to us.
13. Changes
We'll announce changes in the app and on this page. Changes that reduce your rights take effect at least 30 days after we announce them.
