Mark of the Wild

Privacy Policy

Last updated: 23 August 2026

Mark of the Wild is a Chrome extension that stamps a shared prefix onto Steam Community nicknames so a Rust group can find each other in-game. It is not affiliated with Valve, Steam, Facepunch, or Blizzard.

We do not run a backend

The extension does not send your lists, SteamIDs, nicknames, or settings to us. There is no Mark of the Wild server, analytics pipeline, advertising SDK, or crash reporter.

What stays on your computer

Lists you create are saved in Chrome’s local extension storage on this device only (chrome.storage.local). That can include:

List names, colors, and prefixes
SteamID64s you add, plus optional custom names
Steam persona names and avatar URLs resolved from Steam Community
Settings such as request delay and prefix-shuffle options

Uninstalling the extension removes this local data.

Steam Community session

To know whether you are signed in, the extension reads the steamLoginSecure and sessionid cookies for steamcommunity.com in this Chrome profile. It uses them only to detect your SteamID and to let Steam’s own nickname request run in your session. Cookie values are not copied into extension storage and are not sent to any third party.

Network requests

The only host the extension talks to is https://steamcommunity.com. Typical requests:

Set or clear a nickname with Steam’s ajaxsetnickname call
Resolve profile URLs and look up public persona names / avatars
Show a small add/remove control on the Steam friends page

Those requests use your existing Steam Community login. We do not proxy them.

What we do not do

No account to sign up with us
No selling or renting of data
No use of data for credit, lending, or advertising
No tracking across other websites

Children

The extension is intended for people who already use Steam Community and Rust. It is not directed at children.

Changes

If this policy changes, the date at the top will be updated. Continued use of the extension after a change means you accept the updated policy.

Questions about this policy can be sent through the Chrome Web Store support email listed on the Mark of the Wild item page.
