Hankki (한끼채움, "Hankki Chaeum") is a service operated by an individual developer. Our principle is to process your personal information only to the extent necessary and to protect it securely.
The current version does not create member accounts. Your profile, meal records and original photos are stored on your iPhone.
If you have explicitly consented to precise AI analysis, your meal photo is downscaled and sent to the Hankki relay server and to an AI analysis provider. The default analysis provider is the Gemini API of Google LLC; in the event of an outage, Workers AI of Cloudflare, Inc. is used. Data processing by the Google Gemini API is governed by the Google Privacy Policy and the Gemini API Terms of Service. While the free tier of the Gemini API is used, Google may use the photos you send to improve its services, so please make sure your photos do not contain sensitive information such as faces or documents. The Hankki relay server does not store original photos; to prevent duplicate requests, it may keep a one-way identifier generated from the photo, together with the resulting food candidates, for up to 24 hours. You can withdraw your consent to precise analysis at any time in the app settings.
We do not use any external search connection feature for photo analysis.
If you edit a food name in an analysis result and then choose "Report misrecognition / send correction" yourself, the food name found by the AI and the food name you corrected are sent for review to improve recognition. This report does not store your photo, profile, meal time or any IP-based identifier. Reports are kept for up to 90 days and then deleted, and a single report does not immediately change results for other users.
Which "Next meal" suggestions you were shown, opened or logged is stored only on your iPhone for up to 90 days, so the same dishes aren’t suggested again too soon and to power future personalized meal-plan features. It is never sent off your device.
When you tap "Find nearby", only the dish name is passed as a search term to the map app or website you choose (Google Maps or Apple Maps; in Korea also Naver Map and KakaoMap). Hankki does not request, collect or send your location; what happens next is governed by that map service’s privacy policy.
Subscription payments are processed by Apple. Hankki only checks whether a subscription is active and does not directly collect or store payment card information.
You can delete individual meal records within the app. If you delete the app, the profile and meal data kept in the app's on-device storage are deleted along with it. You can change the camera, photo and notification permissions at any time in iPhone Settings.
Misrecognition reports require your separate consent each time you submit one and are never sent automatically. Submitted reports contain no identifying information that could be linked to a person or device, so they cannot be traced back to the submitter, and they are automatically deleted after up to 90 days.
Free users of Hankki see ads (banner ads, a native ad on the meal-suggestion detail screen, and rewarded ads) served through Google AdMob.
The calorie and nutrition analysis provided by Hankki is an estimate and is not a substitute for medical diagnosis or treatment. The precise AI photo analysis service is intended for users aged 18 or older.
For inquiries about the processing of personal information, or for requests to access, correct or delete it, please contact us at the e-mail address above.
Whether you are in the European Economic Area, the United Kingdom, California or elsewhere, you have the right to access, rectify, delete and port your personal data. Because Hankki keeps your data on your device and has no account system, you can exercise most of these rights directly in the app: view and edit your profile and meal records, delete individual records or delete the app to erase everything, and use the export feature under Settings > My data to obtain a portable copy. For any request, or if you need help, e-mail us at the contact address above. Since no account exists, there is no server-side profile for us to delete. The legal basis for processing your photos for precise AI analysis is your consent, which is optional and can be withdrawn at any time in the app settings. Please note that photos sent for analysis are processed by Google LLC (Gemini API) and Cloudflare, Inc. under their own terms and privacy policies, and may therefore be transferred to and processed in countries outside your own, including the United States. We do not sell your personal information.
If our service features or data processing practices change, we will update this policy and announce significant changes in the app or on this public page.
If you have questions, bug reports or suggestions while using Hankki, please contact us at the e-mail address below at any time.
We will do our best to reply within 1–2 business days.
