Privacy Policy

The short version: your data never leaves your browser, because there’s nowhere for it to go.

Last updated: August 22, 2026

What happens to the content you paste

Nothing leaves your device. Conversion, validation, and formatting all run as JavaScript inside the page. This site is a set of static files with no backend, so there’s no conversion endpoint that your YAML could be sent to, and no server-side logs containing it.

You don’t have to trust that statement. Open your browser’s developer tools, switch to the Network tab, and convert something — no request carries your content. Or load the page, disconnect from the internet, and keep working: everything still functions, because everything needed is already local.

What is stored on your device

One entry in your browser’s localStorage, under the key ytj:options, remembering your formatting preferences — indentation width, YAML version, key sorting, and how multiple documents are combined. It never contains the content you convert. Clearing your browser storage removes it.

Cookies

None. The site sets no cookies, so there’s no consent banner to dismiss.

Third parties

Fonts are self-hosted and served from this domain rather than a font CDN. Any third-party page services are separate from the converter itself: the content you paste is handled in your browser and isn’t sent by the converter.

Server logs

Requesting a web page inevitably reveals your IP address and browser user agent to whoever serves it, and our host may retain those in standard access logs for operational and security purposes. That applies to the page itself — never to the content you convert, which is never transmitted.

Changes

If this policy changes, the change will appear on this page. The client-side-only guarantee is the reason this tool exists, so it isn’t something we intend to revisit.
