Your file stays close.

HXSL Tools is designed for local-first processing. A browser task uses the selected file in the current page. It does not upload automatically, write file content to localStorage, or send file bytes to analytics.

Server tasks

Tasks labelled server or hybrid require a visible consent choice before upload. A job receives an unpredictable identifier and a separate authorization token. Inputs and results live in protected temporary directories, are not placed in public static files, and are scheduled for cleanup after 15 minutes by default. Cancellation and deletion clean the job immediately.

What is retained

The build keeps only short-lived job metadata needed to process and download a result. Passwords and file contents are not written to logs. No analytics SDK is loaded by default. Operators can change limits and retention through environment configuration.

A manual language choice is saved in the hxsl-locale cookie on this browser for up to one year. It stores only a language code, not file data. Clear the site's cookies to restore browser-language detection. Explicit language links keep their language.

Limits of the promise

Temporary deletion describes application lifecycle management, not independently verifiable physical erasure from storage. Always review sensitive files before sharing.
