Your file stays yours.

Local file inspection

The inspector reads only the first 26 bytes of a file you select. It does not upload the file, save it to a server, or change it. The report and filename exist in page memory until you clear the result or leave the page. Downloading a report saves a file on your device.

Preferences and accounts

There is no account, payment flow, advertising script or browser storage for your files. Checklist progress and filters reset on reload. Your browser may retain its own history and downloads.

Optional action measurement

Production builds may count a small fixed list of actions, such as opening official resources or exporting a report, through our own server. These event requests do not include filenames, file contents, dimensions or a user identifier. Local previews, automated browser checks and visits marked with ?qa=1 do not send these events. QA mode follows same-site page links for that visit. Browser Do Not Track and Global Privacy Control disable them.

Hosting and external links

Our hosting infrastructure may record ordinary access logs including IP addresses, requested paths and browser information for operations and security. External sites such as GitHub have their own policies when you follow a link. Contact support@sailtoworld.com with privacy questions.
