exif.pl — Copyright and Proprietary Rights Notice

Copyright © 2026 Lilo Huang. All rights reserved.

1. Ownership and scope

Except for the third-party materials identified in THIRD_PARTY_NOTICES.md and published at https://exif.pl/legal/THIRD_PARTY_NOTICES.html, all original portions of exif.pl and its EXIF metadata viewer are proprietary works owned by Lilo Huang, to the extent protected by applicable law. Protected material includes, without limitation, original source and object code, metadata-processing integration, application logic, the selection and arrangement of features, user-interface design and interactions, documentation, text, graphics, icons, styling, and other original creative content.

This notice claims rights only in protectable material owned by Lilo Huang. It does not claim exclusive rights in ideas, facts, metadata values, file formats, methods of operation, public standards, browser APIs, generic photographic techniques, third-party materials, or user content.

2. Limited permission for normal use

Visitors may access and run the official exif.pl service at https://exif.pl/ for its intended end-user functions. This limited permission includes only the transient and cached browser copies technically necessary to load and run the authorized service and to save metadata exports generated through normal use. It does not transfer ownership or authorize redistribution, publication, or deployment of any protected part of the service.

3. Rights expressly reserved

Unless Lilo Huang gives prior written permission, or applicable law grants a right that cannot be waived, no permission is granted to:

- reproduce, retain, or download protected material for redistribution or deployment;
- copy, modify, translate, adapt, or create derivative works from protected material;
- distribute, publish, sublicense, sell, rent, commercially exploit, or otherwise make protected material available to others;
- host, mirror, clone, frame, proxy, embed, white-label, repackage, or redeploy the site or application, in whole or in substantial part, on another domain, service, application, repository, or distribution channel;
- extract or reuse original interface assets, documentation, layouts, styling, or other substantial parts of the application;
- remove, conceal, alter, or falsify copyright, attribution, provenance, build, or rights-management information; or
- use the exif.pl name, branding, visual identity, or domain in a manner likely to imply authorization, sponsorship, affiliation, or origin.

4. Official deployment and unauthorized copies

The authorized public deployment is https://exif.pl/, unless Lilo Huang expressly identifies another deployment in writing. A copy appearing at any other domain or in another product should not be assumed to be authorized. The presence of this notice, the exif.pl name, or a copied attribution line on another service does not authorize that copy and does not transfer any rights.

5. User content and exports

exif.pl does not claim ownership of photographs, files, metadata, or exported data supplied or created by its users. Rights in those materials remain with their respective owners. Users are responsible for ensuring that they have the rights necessary to process, inspect, export, and share their materials.

6. Third-party materials

Third-party authors and licensors retain all rights in their respective components. Those components are governed solely by the licenses and notices identified in THIRD_PARTY_NOTICES.md and its published copy. Nothing in this notice limits rights granted directly by a third-party license, and no third-party license grants any right to exif.pl's original proprietary material.

7. Terms of Use

Access to and use of the service are also governed by the Terms of Use published at https://exif.pl/legal/TERMS_OF_USE.html.

8. No implied license or waiver

No license is granted by implication, estoppel, public availability, access to browser-delivered code, or otherwise. Failure to enforce a right in one instance is not a waiver of that right in any other instance. All rights not expressly granted are reserved.

This document is a copyright and proprietary-rights notice. It is not an open-source license.
