Privacy Policy
Last updated: October 2026
Our Core Privacy Guarantee
Your files, documents, and inputs are never sent to ZainForge servers. All PDF, image, and text processing runs strictly in your local browser memory using WebAssembly and native client-side APIs.
1. Document & File Processing
When you select or drop a file into any ZainForge tool (such as Merge PDF, Compress PDF, Protect PDF, or Image Compressor), that file is read directly by your web browser via standard HTML5 File APIs. It is never uploaded to any remote server, cloud bucket, or third-party processor.
When you complete an operation or navigate away from the page, all allocated memory is released by your browser. No copy or trace of your document contents is ever retained by ZainForge.
2. Local Storage & Preferences
ZainForge uses minimal browser storage solely to remember user-controlled preferences, such as your selected color theme (Light/Dark/System). These values never leave your device and contain no personally identifiable information.
3. Network Requests & Telemetry
ZainForge may collect standard anonymous web traffic telemetry (such as page views, browser type, and referral domains) purely for operational stability, performance monitoring, and capacity planning. This telemetry contains no information about the files or content you process in our tools.
4. Third-Party Services
Our web application is delivered over secure HTTPS. Fonts and assets are self-hosted to avoid third-party network tracking. We do not sell, rent, or trade any user data with advertising networks.
5. Contact
If you have questions regarding this Privacy Policy or the security architecture of ZainForge tools, please reach out via privacy@zainforge.com or open an issue on our GitHub repository.
