Privacy Policy

Utilistack is designed with privacy as a core principle. Here's how each tool handles your data:

• Image Converter: Uses the HTML5 Canvas API to process images entirely in your browser. Images are never uploaded to any server.
• QR Code Generator: Generates QR codes using client-side JavaScript. Your URLs, WiFi passwords, and contact information stay on your device.
• JSON Formatter: Parses and formats JSON using browser-native JSON methods. Your data never leaves the page.
• Password Generator: Uses the Web Crypto API (crypto.getRandomValues) for cryptographically secure random password generation. No server communication occurs.
• YouTube Thumbnail: Fetches publicly available thumbnail images directly from YouTube's CDN (img.youtube.com). Only the video ID is used to construct the URL.

We use minimal browser storage for essential functionality only:

• Theme Preference: Stores your light/dark mode preference in localStorage.
• Tool History: Some tools store recent items in sessionStorage (cleared when you close the tab).

We do not use tracking cookies, advertising cookies, or any third-party analytics that track individual users.

We may use privacy-respecting analytics (such as Plausible or Umami) to understand aggregate usage patterns. These services:

• Do not use cookies
• Do not collect personal information
• Do not track individual users across websites
• Are fully GDPR and CCPA compliant
