Minimal data, local by default

What the site does not collect

The site uses no accounts, cookies, or advertising trackers. Search, filters, the Compose editor, and the configuration generator run in your browser. Fossary does not send editor contents, generator answers, or generated secrets to its server or analytics service.

What stays in your browser

For convenience, localStorage may retain the theme, catalog view, recent searches, favorites, comparison list, server profile, Compose drafts, and editor interface state. This data remains on your device and is not synchronized by the site.

Hosting logs

The infrastructure serving static files may technically process your IP address, request time, URL, response status, and User-Agent for delivery, security, and diagnostics. Fossary does not use this data for advertising or user profiling.

Cloudflare Analytics and external links

On fossary.com, your browser loads the Cloudflare Web Analytics script and sends visit and page-performance measurements to Cloudflare, including page URL, referrer and browser information. The service does not use cookies or localStorage for analytics. We do not configure download or generator events. Application websites, GitHub, and other external resources apply their own privacy policies after you follow a link. Feedback links open prefilled GitHub issues; nothing is submitted until you submit the issue on GitHub.

Your control

You can remove local data through your browser's site settings or by clearing localStorage for fossary.com. Blocking the analytics script does not prevent using the catalog or generators. Do not post personal data, secrets or vulnerability details in public GitHub issues.
