# OnceKit Privacy Policy

Last updated: June 7, 2026

This Privacy Policy explains how OnceKit collects, uses, stores, shares, and protects your information. By using the OnceKit app, website, or related services, you acknowledge the data practices described in this policy.

OnceKit is provided by ZAADN INFORMATION CO., LTD. If you have questions about this policy, data deletion, or privacy rights, contact us at support@zaadndesign.com.

## 1. Scope

This policy applies to the OnceKit app, OnceKit website, cloud synchronization, recognition features, subscriptions, and related services.

This policy does not apply to third-party websites, stores, or service providers acting under their own privacy policies. When you use Apple, Google, or another third-party service, that provider may process your data under its own policy.

## 2. Information We Collect

OnceKit collects information depending on the features you use.

### 2.1 Account and Login Information

- Email address, display name, user ID, and OnceKit ID.
- Login method, provider identifiers, and verification status.
- Account creation time, update time, language, and region preferences.

### 2.2 Content You Enter, Upload, or Import

- Text records, diary entries, life events, tags, summaries, timestamps, locations, amounts, health-related fields, and workout-related fields.
- Photos, image content, screenshots, and recognition results used for camera recognition, album import, or screenshot import.
- Life records, weekly reviews, overviews, and related structured content that you choose to save.

### 2.3 Location and Context Information

- Location information you provide or allow OnceKit to access.
- Place names, addresses, coordinates, or nearby place information associated with your records.

### 2.4 Subscription, Payment, and Usage Quota Information

- OnceKit Pro subscription status, purchase or restore results, and access status.
- Monthly free quota usage, image recognition quota usage, record creation counts, and anti-abuse usage data.
- OnceKit does not store full payment card numbers on its own servers. Payments are processed by the store used for purchase, and subscription service providers help verify access and restore purchases.

### 2.5 Technical, Device, and Security Information

- Device type, operating system, app version, language settings, and network request information.
- Error logs, diagnostics, security logs, abuse prevention data, and service stability information.

## 3. How We Use Information

We use information to:

- Create, authenticate, verify, and maintain your account.
- Turn your inputs and imports into life records, overviews, weekly reviews, and personalized content.
- Perform AI text parsing, image recognition, classification, summarization, search, and structured extraction.
- Sync, back up, and restore your data across devices or after reinstalling the app.
- Verify OnceKit Pro subscription status, restore purchases, manage free quotas, and prevent abuse.
- Maintain service security, troubleshoot errors, improve product quality, and send important service notifications.
- Comply with legal, tax, accounting, security, and dispute-resolution obligations.

## 4. AI, Photos, and Screenshots

When you use text input, camera recognition, album image selection, screenshot import, or diary mode, OnceKit may send relevant content to AI service providers for recognition, classification, summarization, field extraction, or structuring.

AI output may be incomplete, inaccurate, or not reflect your actual situation. You should review records, amounts, calories, exercise details, health fields, places, and other AI-generated fields yourself. OnceKit AI output is not medical, legal, financial, tax, or other professional advice.

## 5. How We Share Information

OnceKit does not sell your personal information.

We share or disclose information only in the following situations:

- With cloud hosting, database, storage, AI, notification, analytics, error diagnosis, or security service providers as necessary to provide the service.
- With Apple, Google, or other store and subscription service providers for payments, subscriptions, purchase restoration, and access verification.
- When you actively share content through a system sharing feature, recipients may see the information you choose to share.
- When necessary to comply with law, court orders, regulatory requests, protect user safety, investigate abuse, or protect OnceKit rights.

## 6. Third-Party Services

OnceKit may use third-party services such as:

- Cloud hosting and database services for API delivery, synchronization, and storage.
- Login, notification, analytics, or crash-diagnostics service providers.
- Apple, Google, and subscription service providers for store payments, subscription verification, and purchase restoration.
- AI service providers for text, image, and screenshot recognition and summarization.

Third-party providers may process information under their own policies. OnceKit uses these services only as needed to provide and improve the service.

## 7. Data Retention and Deletion

We retain information for as long as necessary to provide the service, maintain accounts, synchronize data, process subscriptions, comply with legal obligations, resolve disputes, prevent abuse, and maintain security.

You may request account and personal data deletion through the app settings or by contacting support@zaadndesign.com. We will process deletion requests within a reasonable period, but some information may be retained when required for legal, accounting, security, dispute-resolution, or anti-abuse purposes.

Deleting your account may prevent you from accessing saved records, subscription associations, and personalized data.

## 8. Security

OnceKit uses reasonable technical and administrative measures to protect information, including access controls, database and API security, login verification, error monitoring, and abuse monitoring.

No internet service can guarantee absolute security. You are also responsible for protecting your account, password, device, and login credentials.

## 9. Children and Minors

OnceKit is not designed for children under 13. If your jurisdiction requires a higher minimum age, you must meet that minimum age or use the service with required consent from a parent or legal guardian.

If we learn that a child below the applicable age has provided personal information without required consent, we will take reasonable steps to delete that information.

## 10. International Data Transfers

OnceKit uses cloud hosting, AI, subscription verification, and other service providers that may be located outside your country or region. By using OnceKit, your information may be transferred to, stored in, or processed in other regions as described in this policy.

## 11. Your Rights

Depending on your location, you may have rights to:

- Access personal information we hold about you.
- Correct inaccurate or incomplete information.
- Request deletion of your account or personal information.
- Object to or restrict certain processing.
- Request a portable copy of your data.
- Withdraw certain consents.

To exercise these rights, contact support@zaadndesign.com. We may need to verify your identity before processing requests.

## 12. Policy Updates

We may update this policy from time to time. If changes are material, we will notify you through the app, website, or another reasonable method. Continuing to use OnceKit after an update means you understand the updated policy.
