Privacy Policy

Local processing

Everything you open, paste, or type into YAML Hub is processed on your PC. Formatting, validation, JSON Schema checks, conversion to other formats, Table View, Tree View, and code generation run inside the app, without a server.

The developer does not receive your documents, their content, file names, or information about how you use the app. This holds even when your content contains personal or sensitive information.

The editor, Table View, and Tree View are displayed with Microsoft Edge WebView2, a component of Windows. Their pages are bundled with the app and loaded from your PC.

Data stored on your PC

YAML Hub keeps the following in its app data folder on your PC:

• Your settings, such as theme, editor options, default action, and layout
• Schema choices you make for a document, which can include that document’s file path, so the same schema is used next time
• A list of recently used schemas
• Downloaded JSON Schemas and their download dates, kept in a size-limited cache
• A downloaded copy of the SchemaStore catalog, if you refresh it
• Temporary files created when you share a result as a file

Files you open stay where they are, and files you save go to the location you choose. None of this data is sent to the developer.

Clipboard

By default, when YAML Hub starts it reads the text on your clipboard and, if it is valid input, places it in the editor. You can turn this off in Settings → Auto paste clipboard on startup. The app also reads the clipboard when you choose Paste, and writes to it when you choose Copy. Clipboard content is used only inside the app.

Internet connections

YAML Hub makes a network request only in these cases:

• Load from URL. When you enter a URL, the app downloads the content at that address.
• Schemas your document declares. If a document declares a schema address, the app downloads that schema to validate the document.
• Schemas matched from the catalog. If a file’s name matches an entry in the bundled SchemaStore catalog, such as docker-compose.yml, the app downloads the matching schema. This is on by default; turn it off in Settings → Attach matching schemas automatically, or for one document with Detach schema or Don’t suggest for this input in the schema menu.
• Schemas you add. When you attach a schema from a URL, the app downloads it.
• Cache checks. After a downloaded schema’s cache period ends, the app asks the server whether it has changed before using it again.
• Catalog refresh. When you choose to refresh the schema catalog in Settings, the app downloads the latest catalog from schemastore.org.

These requests ask only for the file at the given address. They never include the content of your documents. Like any web request, they show the server your IP address and standard request details such as the app’s user agent. The sites you download from, including schemastore.org and the hosts its schemas point to, handle that information under their own privacy policies. SchemaStore is an independent open-source project and is not affiliated with YAML Hub.

Without an internet connection, everything except these downloads keeps working, and previously downloaded schemas are used from the cache.

Previews, saving, and sharing

HTML and Markdown output can be previewed in a separate window. The preview displays the generated output on your PC and does not follow links. If your data contains addresses of images or other resources, the preview may load them from those addresses.

When you save, copy, or share a result through the Windows share window, the destination you choose receives that content and handles it under its own terms. Links in the app, such as the bug report page, open in your web browser.

Accounts, purchases, and tracking

YAML Hub has no account or sign-in, and there is no account data to delete. It contains no in-app purchases or license keys. It does not include advertising, analytics, crash reporting, or tracking SDKs, and it does not sell or share personal information.

Microsoft Store and Windows

YAML Hub is distributed through the Microsoft Store, which handles downloads, installs, updates, and reviews under Microsoft’s privacy statement. The developer receives aggregate reports from the Store, such as install counts by country, version, or Windows version, and crash and hang reports collected by Windows according to your diagnostic data settings. These reports do not identify you to the developer.

Retention and deletion

The developer does not hold copies of anything you process in YAML Hub. Data stored by the app stays on your PC until you remove it:

• Clear downloaded schemas in Settings with Clear cache.
• Restore default settings in Settings with Reset settings.
• Uninstalling YAML Hub removes its app data folder, including settings, schema choices, and the schema cache.

Files you saved, shared, or copied elsewhere are not removed by uninstalling. Delete them separately, including any copies in cloud storage or backups.

Support and privacy requests

If you contact Mohammed Aadhil at [email protected], your email address, message, and any attachments are used to respond to your request. Email providers process that correspondence to deliver and store it. It is kept as long as needed to handle your request and any related legal obligations, and you can ask for it to be deleted. If you report a bug on GitHub, GitHub’s own privacy statement applies to what you post there.

Please do not send passwords, API keys, tokens, or confidential documents in a support request; a small sample with made-up values is enough to reproduce most problems. Depending on where you live, you may have rights to access, correct, or delete personal information held about you. Contact the same address to exercise them.

Children’s privacy

YAML Hub is a general-purpose developer utility and is not directed at children. The developer does not knowingly collect personal information from children. If you believe a child has supplied personal information in a support request, contact [email protected] to have it removed.

Changes to this policy

This policy may be updated when the app or its data practices change. The latest version will be available at this address with a revised date.
