Privacy Policy

Last Updated: September 11, 2026

Welcome to FoodLog (hereinafter referred to as "the App"). We value your privacy and strive to handle data in a transparent, necessary, and minimal manner. This policy explains: the types of information the App may process when you use its features, how such information is used, and how you can manage and delete related data.

1. Scope of Application

This policy applies to data processing activities when you use features such as food logging (photos or text), nutrition statistics and weekly reports, weight, water, steps, and exercise tracking, record synchronization, account sign-in, membership services, and related functionalities through the App.

2. What Information We Process and How We Use It

During your use of the App, we may process the following types of information based on the features you enable, device permissions you grant, and your actual operations. Some information is processed and stored only on your device and is not uploaded to our servers; when you actively use online features, data directly related to those features will be sent to the corresponding services only to the extent necessary.

• Information you actively provide or configure: For example, the meals you log (photos and text notes), your daily calorie goal, health records such as weight and water intake, and information you submit when using account sign-in, membership, or other online services, used to provide the relevant features and respond to your actions.
• Information processed and stored only on your device: For example, food records, calorie goals, preference settings, cache, on-device identifiers, and local login status, used to save usage state, maintain continuity of experience, and support troubleshooting. Such information is stored locally on your device by default and is not collected online by us.
• Information required for online features: When you use account sign-in (including tourist or email sign-in), record synchronization, membership purchase verification, or other online features, the App may send device information, app and version information, session or identity identifiers, purchase-related credentials, and other data necessary to complete the corresponding features to the relevant services, for the purposes of providing services, verifying identity or entitlements, ensuring security, and complying with legal requirements. In particular, when tourist sign-in is used, the App generates an anonymous device identifier to create a tourist account; food and health records sync automatically after they are saved, records are kept on your device when the network is unavailable, and synchronization resumes once the network is restored.

We follow the principle of minimum necessity when processing the above information, primarily using it to provide core features, ensure service security, maintain service and transaction status, improve product experience, and comply with legal requirements.

3. Food Photo Recognition

The App provides a food photo recognition feature to help you log meals quickly. When you use this feature:

• The App may send photos you take or select to our server for recognition processing.
• Recognition processing is performed entirely on our own servers. Your photo data is never forwarded to or shared with any third party.
• Photo data is used solely to recognize foods and generate record entries. It is deleted immediately upon completion of processing, and we do not retain your photo data.
• The recognized record entries are returned to your device for local storage and saved after your confirmation; no photos or recognition results are retained on the server.
• If you do not use this feature, you can log meals with text instead, and no photo data will be uploaded.

4. Health Data and Device Permissions

• Camera and Photo Library Permissions: When you take photos of meals or choose images from your photo library, the App will request the corresponding permissions. You can grant full access, limited access, or deny authorization.
• Location Permission: When you use the exercise feature to record walking, running, or cycling routes, the App will use location information during use, with your authorization, to track routes and calculate distance, duration, and estimated energy expenditure. You can deny the permission or allow access only while using the App.
• Health Data Permission: When you use health metric features such as steps and weight, the App will request access to system health data (HealthKit on iPhone, Health Connect on Android). Such data (e.g., steps, weight) is used only for display and statistics within the App, and we will not use it for advertising or provide it to unrelated third parties.
• Permission Revocation: You can revoke the above permissions at any time in your device's system settings. After revocation, the related features may no longer be available.

5. Data Sharing and Third-Party Services

We do not sell your personal information. Only to the extent necessary to provide services, complete transactions, or fulfill legal obligations, will we provide data to the following categories of third parties or external services:

• App distribution and account service providers: When you use purchases, subscriptions, or restore purchases within app stores, the related transactions are processed by platforms such as Apple or Google, and we obtain the necessary verification results to confirm your entitlements.
• Payment and transaction-related service providers: When you use payments, order verification, membership synchronization, or similar services, related data may be provided to payment processors or transaction verification service providers.
• Map and location infrastructure services: The exercise route feature may rely on location capabilities provided by the device system or map infrastructure services, and route data is processed in accordance with this policy.
• Legal requirements or rights protection: When required by laws and regulations, legitimate requests from regulatory authorities, or when necessary to protect the legitimate rights and interests of us, users, and the public.

For third-party service providers who access user data pursuant to law or to provide related services, we require them to process the related data with protective measures no less stringent than those described in this policy.

6. Data Storage and Retention

Unless otherwise required by laws, regulations, or regulatory authorities, we only store your personal information for the minimum period necessary for the purposes described in this policy.

If we cease services or operations, we will promptly stop collecting your personal information, notify you in advance in accordance with applicable legal requirements, and delete or anonymize your personal information after the termination of services or operations, unless otherwise required by laws, regulations, or regulatory authorities.

7. Data Security

We have comprehensive encryption and security mechanisms to prevent the leakage of your personal information. We have adopted industry-standard technical and administrative measures to protect the security of your data:

• Local records and configurations are stored in your device's local storage by default and are protected by system-level security.
• Network communications with online services are transmitted through encrypted protocols such as HTTPS to ensure the confidentiality of data during transmission.
• We take reasonable technical and administrative measures to reduce the risk of unauthorized access, disclosure, or misuse, but please understand that no system can guarantee absolute security.

8. Your Rights and Choices

• You can revoke permissions for camera, photo library, location, and health data at any time in your device's system settings.
• You can use the logging features locally only; when you do not use online features, the corresponding data will generally not be sent to our services.
• You can delete specific food or health records within the App. To delete your server-side account and all synchronized data, or to submit a data processing request, you can contact us through the contact information provided in this policy. To protect account and device security, we may need you to provide necessary information to verify the request.

9. Protection of Minors

The App is not designed for children under the age of 13, and we do not knowingly collect personal information from children under 13. If a guardian discovers that a minor has provided personal information to us without consent, please contact us through the contact information in this policy, and we will handle it in accordance with the law after verification.

10. Updates to This Privacy Policy

We may update this privacy policy based on product features, service capabilities, or legal requirements. Updated versions will be published on this page with the latest update date noted at the top. If updates involve significant changes, we will notify you through appropriate means.
