Privacy Policy & Data Security

Privacy Policy & Data Security — Hayyan Tools

Effective Date: 2026

At Hayyan Tools, we are passionately committed to uncompromising digital privacy and security. Our architecture is founded on a core engineering principle: «Your Privacy Is Non-Negotiable». This document transparently outlines our data practices:

1. 100% On-Device Client-Side Processing

All utilities and tools provided on Hayyan Tools — including image resizing, compression, format conversion, PDF merging and extraction, code and JSON formatters, QR code operations, and multimedia processing — execute strictly within your local browser sandbox via modern Web APIs, WebAssembly, and HTML5 Canvas.

2. Zero Server File Uploads

We never upload, read, process, or retain any personal files, photos, or confidential documents on remote servers. All file operations occur entirely in temporary browser memory and are permanently released when the page or tab is closed.

3. Local Storage Disclosure

We utilize your browser's LocalStorage solely to persist interface preferences:

• Theme preference (Dark or Light mode).
• Preferred language (Arabic or English).
• Local administrative overrides saved by the site owner.

These records are never transmitted or used for tracking.

4. Advertising Policy

If advertisements are enabled on the platform (such as Google AdSense or certified ad partners), ad scripts operate strictly within standard sandboxed frames. They have zero access to your uploaded files, processed documents, or clipboard contents.

5. Anonymous & Registration-Free Experience

We do not require accounts, logins, or personal credentials to access our utilities, guaranteeing a fully private, anonymous, and unconstrained user experience.

6. Inquiries and Contact

If you have any questions or feedback regarding our privacy standards, feel free to reach out via our Contact Page or official support channels.
