Privacy Policy

Last updated: March 2026

Overview

ToolCenterLab is designed with privacy as a core principle. All 96 tools — from PDF compressors and mergers to text formatters, image editors, and developer utilities — process your data entirely within your web browser using client-side JavaScript and WebAssembly.

No files, text, images, or calculations are ever sent to our servers. When you compress a PDF, generate a password, or remove an image background, your data never leaves your device.

Data We Do Not Collect

Because all processing happens client-side, we do not collect, store, or have access to:

  • PDFs, images, or files you edit, convert, or compress
  • Text you format, count, or transform
  • Passwords, hashes, or codes you generate
  • Calculation inputs, outputs, or conversion results
  • Personal information such as name, email, or address
  • Login credentials — we have no accounts or signup

Local Storage

We use your browser's localStorage to save your preferences, such as favorite tools and recently used tools. This data is stored only on your device and is never transmitted to any server. You can clear it at any time through your browser settings.

Analytics

We use Google Analytics 4 to understand how visitors interact with the site — which pages are visited, how long sessions last, and which tools are most popular. Google Analytics collects anonymized usage data and may set cookies. No personally identifiable information is collected through analytics. You can opt out by using a browser extension like Google Analytics Opt-out.

Advertising

We use Google AdSense to display ads. Google AdSense may use cookies and similar technologies to serve ads based on your prior visits to this or other websites. You can manage your ad personalization preferences at Google Ads Settings. You can opt out of personalized advertising by visiting aboutads.info.

Cookies

The cookies used on this site come exclusively from third-party services:

  • Google Analytics — anonymized site usage analytics
  • Google AdSense — ad serving and personalization

ToolCenterLab itself does not set any cookies. We use localStorage (not cookies) for user preferences.

Your Rights

Since we do not collect personal data, there is generally nothing to request deletion of. However, you can clear all locally stored preferences (favorites, recent tools) by clearing your browser's site data for toolcenterlab.com. If you have any privacy-related concerns, contact us and we will respond promptly.

Changes to This Policy

We may update this privacy policy from time to time. Any changes will be reflected on this page with an updated "Last updated" date.
