This page explains how gunainaja (operated by Hayyu Tech) collects, processes, and protects your information when you use our services at gunainaja.com.
1. Core principle: privacy by design
Most of our tools process files and data directly in your browser (client-side). This means:
- PDF files, images, and data you process are never sent to our servers
- Compression, merging, resizing, watermarking, etc. all happen on your own device
- We don't store the files you process — no file database

This data is retained for a maximum of 30 days for monitoring and security purposes.
