プライバシーポリシー — KeepProof

KeepProof (hereinafter referred to as "the App" or "we") deeply understands the importance of privacy to you. This Privacy Policy is designed to help you understand how we handle your information.

Core Principle

All data stays on your device. We do not upload any of your data to any server, nor do we share your data with any third party.

1. Information We Collect

We Do Not Collect Any Personally Identifiable Information

KeepProof is a local-first application. All functionality is processed locally on your device. We do not collect any of the following information:

  • ❌ Document images or scans

  • ❌ OCR text results

  • ❌ Notes or annotations

  • ❌ Device information (e.g., device model, OS version, IP address, etc.)

  • ❌ Location information

  • ❌ Usage statistics or analytics

In short: Your documents, scans, notes, and reminders belong only to you and stay on your device forever.

2. Data Storage

  • Document scans and images are saved in your device's local storage

  • OCR extracted text is saved in your device's local storage

  • Notes, categories, tags, and reminder settings are saved in your device's local storage

  • App preferences (such as Face ID toggle) are saved in your device's local storage

We cannot access, read, copy, or transmit this data. When you uninstall the App, all local data will be deleted.

3. Data Deletion

You can delete your data in the following ways:

  • Delete individual documents or records directly within the App

  • Uninstall the App (all local data will be automatically cleared)

4. Permissions

This App requires the following permissions, used solely for on-device processing:

Permission Purpose Data Destination
Camera Scan receipts, warranties, IDs, and other documents Stored locally only, not uploaded
Photo Library Import existing document images or screenshots Stored locally only, not uploaded
Local Storage Save document scans, OCR text, notes, and preferences Stored locally only, not uploaded

You can enable or disable these permissions at any time in your system settings. Disabling permissions may affect the normal use of certain features.

5. Third-Party Services & Data

This App does not use any third-party data analytics services, crash collection services, or advertising services.

The OCR engine in this App runs locally on your device and does not call any cloud APIs. Therefore:

  • Your documents, images, or any data will not be sent to any third party

  • Your data will not be used to train any AI or machine learning models

  • Your data will not be used for advertising or user profiling

6. Face ID / Touch ID

KeepProof optionally uses Face ID or Touch ID to secure your sensitive documents. This authentication is handled entirely by iOS system APIs. We do not have access to your biometric data.

7. Children's Privacy

This App does not collect personal information from any user. We encourage parents to supervise their children's app usage. This App is not designed for children under 13 years of age, nor does it knowingly collect personal information from children.

8. Changes to This Privacy Policy

If we update this Privacy Policy, we will publish the updated version within the App or on the official website. Material changes will be notified through one of the following methods:

  • In-app notification

  • App update changelog

  • Official website announcement
