Recipe Ledger values the protection of your personal information and business data. This Privacy Policy explains how we process your personal information, recipe and production data when you use Recipe Ledger, and the rights available to you.
Please read this Policy carefully before use. By using the App, you acknowledge the information-processing practices applicable to the features you choose.
Recipe Ledger stores business data primarily on your device. Data is transmitted to our servers or third-party services only within the scope described here when you actively use connected features such as accounts, membership, cloud backup, or feedback.
1. Information We Process
1.1 Account and identity information
When you register, sign in, edit your profile, reset a password, purchase membership, or close an account, we may process your email address, phone number, nickname, avatar URL, account ID, login method, identifiers supplied by Apple or Google, membership status, encrypted password result, verification result, and operation time.
We do not store login passwords in plain text. Passwords are encrypted or hashed for authentication and account protection.
1.2 Recipe and business data you provide
When you use ingredient, purchasing, recipe, production, and analysis features, the App processes locally entered, imported, or generated data, including:
- Ingredient name, category, unit, specification, purchase price, usable yield, supplier, purchase location, purchase records, and notes;
- Recipe name, images, ingredient quantities, product yield, cost snapshots, selling price, gross margin, versions, steps, process parameters, and development notes;
- Preparation plans, purchase lists, progress, actual usage and output, qualified output, waste, tasting quantities, loss, time spent, and production reviews;
- Costs, profits, price-change impacts, analysis results, and prompts calculated from that data.
This data is mainly stored on your current device to provide recipe management, cost calculations, production scaling, and business analysis.
1.3 Images, files, and feedback
When you select an image for a recipe, production record, or feedback, the App reads the selected file. Recipe and production images are stored for local display by default. Feedback images you actively submit are uploaded to object storage so we can identify and resolve your issue.
We may also process the feedback type and content, contact details, submission time, replies, and image links you provide.
1.4 Backup, import/export, and membership information
When you export, import, back up, or restore data, we may process selected files, backup contents, time, file size, backup and restore records, and account ID. For membership purchase, restore, or synchronization, we may process order identifiers, transaction receipts, purchase and expiry times, membership level, and platform status.
1.5 Device and service-operation information
To operate connected services and troubleshoot errors, we may process operating-system type, app version, request time, IP address, API errors, login state, and an app-generated guest identifier. We do not actively collect contacts, SMS or call history, precise location, microphone recordings, health information, or identity-document information.

We do not use your personal information or business data for other purposes unless described in this Policy, separately authorized by you, or required by law.

4. Storage and Protection
4.1 Location and retention
Local business data is stored on your current device. When you actively use cloud backup, accounts, membership, or feedback, related data is stored on servers or object storage located in the People’s Republic of China. We retain it only as needed to provide the feature, resolve disputes, meet legal obligations, and maintain security.
4.2 Security measures
We use reasonable technical and organizational safeguards, including encrypted transmission, password hashing, access controls, backup access verification, object-storage upload policies, audit logs, and abnormal-request protection. No internet environment is absolutely secure, so protect your account, verification codes, device, and exported files.
4.3 Local data reminder
Uninstalling the App, clearing app data, device damage, system reset, or changing devices without a completed backup may cause local data loss. Export backups regularly and export current data before restoring a backup.
5. Sharing, Transfer, and Public Disclosure
We do not sell your personal information or business data such as recipes, purchasing, or production records. To provide services, we may share necessary information with:
| Provider | Purpose | Information that may be processed |
| Apple | Sign in with Apple and App Store membership purchase/restore | Apple identifier, transaction receipt, and subscription status |
| Alibaba Cloud services | Server operation, object storage, SMS, and cloud infrastructure | Account data, backup files, feedback images, and necessary request information |
| Email service provider | Email verification, password reset, and necessary account notices | Email address and delivery status |
| Google | Google sign-in when you choose it | Google authorization identifier, nickname, or email |
Sharing is limited to what is necessary to provide services. We do not transfer or publicly disclose personal information except with your express consent, as required by law, to protect users or public safety, or in a lawful merger, division, or reorganization.
6. Your Rights
Subject to applicable law, you may access, review, correct, supplement, delete, withdraw consent, close your account, request a copy, complain, or provide feedback.
- Review, edit, or delete local business data from the ingredient, recipe, production, and analysis pages;
- Edit your nickname, sign out, or close your account under Me - Account;
- Export a backup under Me - Data Backup / Restore, or use cloud backup and restore when eligible;
- Submit privacy, account, data, or service questions under Me - Feedback;
- Contact kefu@jizekj.com. We may request necessary information to verify your identity and protect your account.
After account closure, we stop account-related services and delete, anonymize, or retain necessary information as required by law. Closing an account does not automatically erase local data on the current device. Cloud backups, membership, and order data are handled according to legal and service requirements.
7. Children
Recipe Ledger is primarily intended for adults, operators, and professionals who manage recipes, production, and costs. If you are a minor, use the App with consent and guidance from a guardian. If we discover that a minor’s personal information was processed without required guardian consent, we will take appropriate measures as required by law.
8. Policy Updates and Contact
We may update this Policy due to changes in law, product features, third-party services, or operations. Material changes will be communicated through the App, this page, or other reasonable means. Continued use means you acknowledge the updated Policy.
