Privacy policy

Last updated: 15 November 2026

Ocellus is a static site. There is no server application behind it, no database and no account system. This page states exactly what that means for your data.

What this site does not do

  • No account is required, and none can be created.
  • No cookies are set by this site.
  • No analytics, telemetry or error reporting service is loaded.
  • No third-party scripts are loaded by these pages. The fonts are self-hosted and served from this origin, so no font CDN sees a page view.
  • No tracking pixels, no fingerprinting, no advertising identifiers.

What happens when you run a scan

Your browser sends the hostname you entered to the public services listed on the method page. Those services see the scanned hostname and your IP address, in the same way any website you visit sees them. Their own handling of that request is governed by their policies, not by this one.

Nothing is sent to a server operated by this site, because there is no such server. The requests are made by your browser directly to each source, and the answers are processed in the page.

What is stored on your device

Two values are written to browser storage, and both stay on your device:

  • The last report, in sessionStorage under the key ocellus.report.v1, so that reloading the results page still shows the report you just ran. Session storage is cleared when the tab or browser is closed.
  • Your theme choice, in localStorage under the key ocellus.theme, so the site does not flash the wrong theme on the next visit. You can clear it at any time through your browser settings, and the site will follow your system preference again.

Both are readable only by this site in your browser. Neither is transmitted anywhere. If storage is blocked or unavailable, the scan still runs; it simply cannot restore the report after a reload.

Personal data

No personal data is collected, stored, sold or shared by this site. There is no database of scans, no list of visitors and no profile of anyone. A scanned hostname is not personal data in the hands of this site, because this site never receives it.

Contact

There is no email address for this project. Any question, correction or data request can be raised as an issue at https://github.com/izynu/ocellus/issues, which is public by design.

Changes

If this policy changes, the date at the top of the page changes with it. Because the site stores nothing about you, a change is unlikely to affect data already held: there is none.
