Elden Ring Tracker extension: privacy

Updated 4 September 2026

The extension reads your Elden Ring save file from disk and hands it to the tracker page open in the same browser. It does nothing else: it has no network permissions, no server of its own and no analytics.

What data is processed

  • The contents of ER0000.sl2 — character names, levels, play time and progress. The file is read in full so it can be handed to the tracker.
  • The path of the chosen file and the Steam account folder number — shown in the extension window so you can see what it watches.
  • The file's last-modified time and the time of the last hand-off — so the same file is not sent twice.

Where the data goes

  • Only to the tracker page open in your browser: eldenring.krut.top (and localhost if you run the site yourself). The list of addresses is fixed in the extension manifest; it does not answer any other page.
  • The hand-off happens inside the browser, between the extension and the tab. The extension makes no network requests at all — it holds no permission to.
  • No third parties, ad networks, counters or analytics are involved.

What is stored, and where

  • The file path, account number, character summary and timestamps live in the browser's local extension storage (chrome.storage.local) on your computer.
  • The save contents are not stored anywhere: the file is read from disk and passed straight to the tab.
  • Removing the extension removes that local storage with it.

Permissions and why

  • File access (file:///*) — the only way to read the save: it lives in %APPDATA%\EldenRing, where a web page is not allowed to look. The extension reads ER0000.sl2 files and lists folders to find them.
  • storage — remember the chosen file between browser restarts.
  • alarms — a fallback timer that resumes watching if the browser suspends the extension's background worker.
  • No permissions for tabs, history or arbitrary sites are requested.

What the site itself does with the file

  • The save is parsed in your browser, on the tracker page. Progress, character names and coordinates stay in the tab unless you sign in and turn on syncing yourself.
  • The extension changes none of that: it hands over exactly the file you would otherwise upload by hand.
