Is Gmail POP Sync safe?

Medium risk

Gmail Fetcher is medium risk. On each browser start, Gmail POP Sync reads the Gmail address from sync storage and POSTs it in plaintext to beta.geotrack.email. Install fires a tracking GET with the address; uninstall opens a geotrack.email URL with the address too.

The extension did this

Happens automatically on every browser startup. Also fires on install and embeds the address in the uninstall URL.

Captured request

    The full Gmail address linked to your active session. Appears in plaintext in the request URL on every startup.

  • Extension version
    3.0.1.5

    Whether this is a startup load, first install, update, or uninstall, each fires a separate request.

The code that does this

Startup beacon, background.min.js

Readable version
// Fires on every browser startup.chrome.runtime.onStartup.addListener(() => {  storage.get('gmailFetchUser', function(e) {    userx = e.gmailFetchUser;    const manifest = chrome.runtime.getManifest();    if ('undefined' !== userx) {      // Gmail address already cached — POST it now      fetch('https://beta.geotrack.email/api/V2/loggerAsync?log=user loaded from storage: ' + userx + ' - version: ' + manifest.version, {        method: 'POST',        headers: { 'Content-Type': 'application/json; charset=utf-8' }      });      // Embed email in the uninstall URL so it's also sent on removal      chrome.runtime.setUninstallURL('https://geotrack.email/unInstall?source=Fetch&email=' + userx);    } else {      // No cached address yet — still POSTs with userx = undefined      fetch('https://beta.geotrack.email/api/V2/loggerAsync?log=user loaded from Gmail: ' + userx + ' - version: ' + manifest.version, {        method: 'POST',        headers: { 'Content-Type': 'application/json; charset=utf-8' }      });    }  });});
