Privacy Architecture

The Zero-Upload Technical Guarantee

PixelPlane operates entirely within your browser's local sandbox using the modern HTML5 Canvas API, FileReader, and JavaScript TypedArrays. When you drag an image onto PixelPlane:

🔒

No Network Transmission

Your image is decoded into volatile browser RAM. Not a single byte is transmitted across the internet to any API, server, or cloud storage bucket.

⚡

DevTools Verifiable

You can verify this yourself: open your browser's Developer Tools (F12) > Network tab, process an image, and see that zero outbound HTTP POST/PUT requests occur.

How PixelPlane Compares to Cloud Image Tools

Cloud-based image utilities collect your media on their disks, analyze them, and often enforce strict bandwidth caps or watermarks. Here is how PixelPlane is fundamentally different:

Factor	Traditional Cloud Editors	PixelPlane Architecture
Image Destination	Uploaded to remote cloud servers	Remains 100% on your local machine
Server Disk Retention	Saved on disks (1 hour to indefinite)	Never touches any disk outside your device
Internet / Bandwidth Latency	Subject to upload and download speeds	Instant zero-latency GPU rendering
Account / Login Requirement	Email, account, or credit card required	No accounts, no logins, no paywalls
Cookies & User Tracking	Marketing trackers & analytics pixels	Zero tracking pixels, zero analytics scripts
Offline Capability	Fails without an active connection	Works completely offline once loaded

Metadata & EXIF Protection

Smartphones and digital cameras automatically inject rich metadata into every photo you take. This often includes:

Exact GPS coordinates (latitude, longitude, altitude) pointing directly to your home or office
Device serial numbers and unique hardware identifiers
Exact capture timestamps, lens configuration, and exposure settings
Embedded thumbnail caches of previous uncropped edits

When you use PixelPlane's Clean & Strip EXIF tool or re-export through our compression pipeline, the image pixels are rendered afresh onto an HTML5 canvas element. This mathematically discards all embedded EXIF, IPTC, and XMP metadata chunks, ensuring your shared media is sterile and safe.

What Information Is Stored Locally?

PixelPlane uses browser localStorage strictly for user convenience to remember your visual theme preference:

pixelplane-theme: Set to either "dark" or "light" so your theme preference persists between browser visits. No personal data, session tokens, or image history is ever written to storage.
