1. General Statement

The App allows users to select or drop a file, optionally stream clipboard content, encode supported content as HCC2D images, and display the resulting frames locally on screen for optical transfer.

The App is designed primarily for local on-device use. File content selected by the user, clipboard content explicitly requested by the user, file references, streaming settings, and generated outputs are processed on the user's Mac for the purpose of providing the requested functionality.

The App does not require a user account and does not use submitted file content or clipboard content for advertising, profiling, or analytics purposes.

By using the App, users acknowledge and agree that data may be processed locally on their device as described in this Privacy Policy.

2. Definition of Personal Information

"Personal Information" refers to any information relating to an identified or identifiable natural person, in accordance with applicable laws including the General Data Protection Regulation (GDPR) and the Personal Information Protection Law of the People's Republic of China (PIPL).

3. File Content, Clipboard Content, and Local Processing

When using the App, user-provided data may include file content selected by the user, clipboard content explicitly requested by the user, file paths selected by the user, streaming settings, and generated encoded data. Depending on what the user provides, this data may contain personal information.

This data is processed locally on the user's device in order to:

Generate HCC2D images
Prepare local optical transfer sessions
Restore limited local app state between launches
Maintain app reliability and security

We do not intentionally transmit file content or clipboard content to our servers as part of the App's normal streaming workflows.

4. Local Storage and App State

The App may store data locally on the user's device, including:

The path and security-scoped bookmark for the last selected file, where applicable
Security-scoped bookmarks for files selected by the user
The user's accepted privacy-policy version marker
The user's selected language preference
Limited local app state needed to restore continuity between launches

This information is stored solely to provide App functionality and continuity between launches.

5. No Network Communication

Core encoding and streaming workflows operate locally on the user's device.

The App is designed to function offline and does not initiate network communication as part of its normal operation.

The App does not transmit file content, clipboard content, generated encoded data, or other user content outside the user's device.

The App does not transmit personal information to any external systems. This means that the App does not transmit, upload, share, sell, rent, or trade personal information with the developer or any third parties.

6. Local Logs and Diagnostics

The App does not use advertising SDKs, third-party analytics SDKs, or profiling systems.

The App may write local diagnostic or debug information only in limited circumstances, such as when an optional debug logging mode is explicitly enabled. Such logs remain on the user's device unless the user chooses to share them.

Crash reports and system diagnostics may also be generated by macOS according to the user's system settings and Apple's platform behavior. Such reports are governed in part by Apple's operating system and account settings.

7. Legal Basis for Processing

We process personal information in accordance with applicable laws, including the General Data Protection Regulation (GDPR) and the Personal Information Protection Law of the People's Republic of China (PIPL).

Under GDPR, processing is based on:

Performance of a contract or service (Art. 6(1)(b))
Legitimate interests (Art. 6(1)(f)), limited to providing local app continuity and maintaining app reliability and security
Consent, where applicable (Art. 6(1)(a))

Under PIPL, processing is based on:

User consent
Necessity for the performance of a contract or provision of requested services
Necessity for maintaining the security and stable operation of the App
Compliance with legal obligations, where applicable

Processing is limited to what is necessary and is carried out in accordance with the principles of legality, legitimacy, necessity, and good faith.

8. Purpose of Processing

Personal information is processed solely for the following purposes:

Generating HCC2D images
Preparing and displaying local streaming sessions
Restoring limited last-used local state
Maintaining app reliability and troubleshooting local issues

9. Data Storage and Retention

We retain data only for as long as necessary for the App's local functionality or until the user deletes it.

In particular:

Last-selected file references and security-scoped bookmarks remain until replaced or cleared
Accepted privacy-policy version markers remain on the device until replaced, updated, or removed
Language preferences and other limited local app state remain until replaced, reset, or removed
Optional debug logs remain on the device until removed

Because these items are stored locally on the user's device, users generally control their retention by managing the App's files, preferences, and local system storage.

10. Data Sharing and Cross-Border Transfer

We do not sell personal information. We do not intentionally share personal information from the App with third parties as part of its normal local streaming workflows.

Because the App is designed to operate locally and without network communication, we do not intentionally transfer file content, clipboard content, generated encoded data, or other user content outside the user's device through the App's normal workflows.

11. User Rights

Under applicable laws, including GDPR and PIPL, users may have the right to:

Access their personal information
Request correction of inaccurate data
Request deletion of personal information
Restrict or object to processing
Request data portability (where applicable)
Withdraw consent (where processing is based on consent)

Certain rights may not be applicable due to the App's offline nature and absence of centralized data processing.

We will respond to requests within a reasonable timeframe, generally within 30 days.

Users may also lodge a complaint with a competent data protection authority.

The App does not provide account registration or identity-based services.

12. Data Security

We implement reasonable technical and organizational measures appropriate to the nature of the App.

Local App data is primarily protected by the user's device security, operating system permissions, sandboxing, and file-access controls. However, no method of storage or transmission is completely secure, and absolute security cannot be guaranteed.

13. Children's Privacy

The App is not specifically intended for children. Where required by applicable law, users below the applicable age of consent should use the App under the supervision of a parent or legal guardian.

14. Updates to This Policy

This Privacy Policy may be updated from time to time. The applicable version is intended to be bundled offline within the App, and any updated version will be included within a future App release.

15. Legal Compliance

This Privacy Policy is designed to comply with applicable data protection laws, including:

General Data Protection Regulation (GDPR)
Personal Information Protection Law of the People's Republic of China (PIPL), where applicable
