Elden Ring & Dark Souls Tracker extension: privacy

Updated 23 September 2026

The extension reads your Elden Ring, Dark Souls III and Dark Souls II save files from disk and hands each one to the tracker page of its game, 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 the save file - ER0000.sl2 (or ER0000.co2 of the Seamless Co-op mod) for Elden Ring, DS30000.sl2 for Dark Souls III, DS2SOFS0000.sl2 for Dark Souls II: 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 darksouls.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. Each game's save goes only to that game's tracker 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, %APPDATA%\DarkSoulsIII or %APPDATA%\DarkSoulsII, where a web page is not allowed to look. The extension reads only these games' save files and lists folders to find them.
  • storage - remember the chosen files (one per game) 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.
