Privacy Policy

This policy applies to your access to and use of the GongJu online toolbox, including every tool page. The Site is maintained as an open-source project; there is no account system, and no registration or login is required.

The Site is built on a local-first principle: every computation runs in your browser. Apart from the static assets needed to load the pages themselves, the Site sends none of your data to any server.

In short: no accounts and no tracking; your data stays on your device; only interface preferences, notes and clipboard history are stored locally; device permissions such as camera and clipboard are requested on demand and used only with your consent.

By using the Site you confirm that you have read and understood this policy. If you disagree with any part of it, please stop using the Site.

The Site does not actively collect any information that identifies you. Specifically:

• No third-party analytics, measurement or advertising scripts are loaded;
• No cookies, pixel tags or device-fingerprinting techniques are used to track you;
• No text you enter, file you upload or result you produce is recorded;
• We do not sell, rent or share your data with any third party — because we never hold it.

Text, files, images, audio and video you work with exist only in browser memory for the duration of the computation and disappear when the page is closed or reloaded. Content is kept on your device only when you deliberately use the Notepad or Clipboard History tools, as described below.

One exception must be stated honestly: the hosting layer. When you visit the Site, the hosting provider and content delivery network (CDN) keep standard access logs, which may include your IP address, browser identifier (User-Agent), request time and the page path requested. Such logs serve security and troubleshooting; the Site does not use them for profiling, tracking or advertising.

The Site uses no cookies. The following items are kept on your device through browser localStorage only — never synced, never uploaded:

• gongju-locale (interface language): stores your Chinese / English choice until you clear site data.
• theme (appearance): stores light / dark / system preference until you clear site data.
• orkest-high-contrast (high contrast): stores the high-contrast toggle until you clear site data.
• gongju-view (home layout): stores the card / list layout preference until you clear site data.
• gongju.notes.v1 (notepad): notes you deliberately save; you add and delete them, and can clear them all inside the tool.
• gongju.clipboard.v1 (clipboard history): text you copy or paste on this Site, up to 50 entries; can be cleared inside the tool.

How to erase: use the Clear button inside the relevant tool, or delete this Site's data in your browser settings. Erasure is irreversible, so export anything important first. localStorage is isolated per origin: other websites cannot read these keys, and they play no part in cross-site tracking.

The Site uses the following permissions only in these scenarios and only after the browser has asked for your consent. Declining a permission does not affect any other tool:

• Camera: used by QR Code Reader (optional live scanning). Frames are decoded locally in real time; nothing is recorded, stored or uploaded, and the camera stops when you leave the tool.
• Clipboard read: used by Clipboard History (when you press “Read clipboard”). The text read is kept only in localStorage on your device and can be cleared at any time.
• Clipboard write: used by the Copy button in every tool. Result text is written to the system clipboard only when you click Copy.

The Site requests no other permissions such as microphone, geolocation or notifications. Any permission you have granted can be revoked at any time in your browser's site settings.

The Site integrates no third-party SDKs, analytics services, ad networks or social plugins. Fonts are downloaded at build time and self-hosted with the Site, so no requests are made to font providers at runtime.

The Site contains links to external websites, such as the GitHub project repository and the Tally feedback forms. Once you click, you leave the Site; those websites' data practices are governed by their own privacy policies, and the Site is not responsible for their content or practices. Anything you submit through the feedback forms is processed by Tally under its own privacy policy and is not sent back to the Site.

Because all processing happens locally, your data never crosses the network, which removes the transmission and server-storage exposure by design. The Site is fully static and keeps no user database, so there is no server-side personal data to breach.

Encryption tools (such as AES-GCM text encryption and file encryption) implement standard algorithms through the browser's native Web Crypto API. Passwords and keys exist only on your device; the Site cannot access them and cannot recover a forgotten password — if you forget it, the encrypted content is unrecoverable.

After using the Site on a shared device, consider clearing its site data so others cannot see your notes or clipboard history.

The Site provides tools to the general public and does not knowingly collect any information from children (in fact, it collects no user information at all). Minors should use the Site under the guidance of a guardian, and encryption or file-handling operations should be carried out with a guardian's knowledge.

This policy applies from the effective date shown at the top of this page. If the Site's features or data practices change — for example, a feature that requires network access is added — we will update this policy and show the new effective date here, with prominent notice for material changes.

We recommend reviewing this page periodically. Continued use of the Site after an update constitutes acceptance of the revised policy.

For any question, comment or complaint about this policy or your data, open a privacy-related question or suggestion through GitHub Issues (Chinese or English both welcome):

We will respond within a reasonable time. Because the Site holds none of your personal data, we cannot fulfil requests to “look up or delete server-side personal data” — your data is always managed by you, on your own device.
