Privacy Policy

Last updated: 20 October 2026

Overview

JsonYard is a free, browser-based workbench for formatting, validating, and converting JSON, YAML, and CSV on your device. This policy explains what happens when you use the site at the published JsonYard origin (and any future domain for the same product).

In short: parsing and conversion run locally in your browser. We do not operate a cloud formatter API for your documents, we do not require accounts, and we do not show ads.

What we process — and what we don’t

We do not receive the text you paste for formatting, validation, or conversion. When you use the workbench, JSON.parse, YAML parsing (via a same-origin library), CSV helpers, and downloads run in your browser. Document contents are not uploaded to JsonYard servers as part of the tool flow.

We do not ask you to create an account. We do not collect names, email addresses, or payment details through this product — there is no checkout and no paid plan.

We do not sell personal data. We do not use advertising networks on this site.

Local processing

Beautify/minify, validation messages, YAML↔JSON and CSV↔JSON conversion, Copy, and Download are handled on the device running your browser. Output files are generated locally and saved through your browser’s normal download mechanism.

Optional preferences — such as language (jsonyard-lang-v1), workbench mode, and indent — may be stored in your browser’s localStorage so they persist between visits on that same browser and device. You can clear them by clearing site data in your browser settings.

Hosting and network logs

The site is a static site hosted on Cloudflare Pages. Like most websites, requesting pages, scripts, styles, and public assets may create standard edge or access logs at the hosting/CDN layer (for example IP address, user agent, URL path, and timestamps). Those logs are used for operating and securing the delivery of the site.

We do not use hosting logs to inspect or reconstruct the content of documents you process, because those documents are not sent to us for processing.

Cookies and local storage

JsonYard does not rely on third-party advertising cookies. We may use browser localStorage (and similar browser storage) for preferences described above. If Cloudflare or the browser itself sets strictly technical cookies for delivery or security, that is outside the workbench tool and is not used by us to track document content.

Analytics

We do not run third-party analytics (such as Google Analytics or Plausible) on this site at the time of this update. If that ever changes, we will update this policy before enabling it.

Third-party scripts

Processing runs with browser APIs and same-origin vendor scripts (for example js-yaml) bundled with the site, not loaded from unrelated third-party ad or tracker domains for the core tool.

Children

JsonYard is a general-purpose utility. We do not knowingly collect personal information from children. Because processing is local and we do not require accounts, we do not solicit such information through the product.

International users

The product UI defaults to English. A Chinese language option is available only when you choose it. Selecting a language stores a preference locally; it does not create an account profile on our servers.

Changes

We may update this policy as the product or hosting setup changes. The “Last updated” date at the top will change when we do. Continued use of the site after an update means you accept the revised policy.

Optional feedback form. If you use the floating Feedback button, we store the email address you enter, your message, which JsonYard site you came from, the page URL, a basic browser user-agent string, and the time of submission in our database so we can read and respond. Tool file processing still runs locally in your browser and is separate from this form. 中文：若你使用右下角「反馈」按钮，我们会保存你填写的邮箱、反馈内容、来源站点、页面地址、浏览器信息和提交时间，便于回复；工具本身的文件处理仍在本地完成。

Contact

For privacy questions about JsonYard, contact the operator via the channels published with the SqueezeCodex / product launch materials for this site. Because we do not hold your pasted documents, we typically cannot retrieve or delete document content from our servers — it was not uploaded for processing.
