100% Client-Side Privacy Policy
At PortalFit, we believe your personal photos (passports, identity documents, visas) should never leave your personal device.
🛡️ Zero Network Guarantee
PortalFit is built with zero network requests. No images are uploaded to any server, cloud service, or third party. Everything is processed directly in your browser using local JavaScript HTML5 Canvas APIs.
How to Verify Local Processing Yourself (DevTools Proof)
- Open PortalFit main page (index.html).
- Press F12 (or Ctrl + Shift + I / Cmd + Option + I) to open browser Developer Tools.
- Click on the Network tab.
- Drag and drop a photo into PortalFit, adjust settings, compress, and download your image.
- Observe the Network log: Zero requests are sent during processing or download.
- Optionally, turn off your Wi-Fi or disconnect internet entirely — PortalFit will continue to work 100% offline!
Technical Principles
- No Server Uploads: Image manipulation uses local browser HTML5 `
- No Analytics Tracking: We do not track, profile, or log user activity or image metadata.
- No Cookies or LocalStorage Scraping: Your files remain transient in memory and are discarded immediately when you close or refresh the tab.
- Memory Hygiene: Generated image URLs are explicitly revoked from memory (`URL.revokeObjectURL`) to ensure your device memory is kept clean.
