1. Fundamental Architecture: On-Device Processing
PixelUp is built from the ground up as a native Windows desktop application. Unlike web-based image manipulation services, PixelUp processes all images locally on your computer hardware.
- No Image Uploads: Your source images, intermediate processing buffers, and exported files are never transmitted to external servers, cloud storage buckets, or third-party APIs.
- Local Storage: Input and output paths are located entirely within your chosen local directories (such as your Windows Pictures folder or custom chosen directories).
2. Network Activity & AI Models
Pixel Up processes images on your device. Network connections are used for the following non-image operations:
- Included AI Models: Pixel Up includes the Real-ESRGAN upscaling models and the open-source BEN2 background-removal model with the application. They run locally and are not downloaded from a remote model repository during use.
- Microsoft Store: The Microsoft Store uses an internet connection to download and update Pixel Up.
- Pro License: If you activate Pro, the application sends your license key and activation identifier to Polar to activate, revalidate, or deactivate your license. Temporary offline access may be available after a successful online verification, but continued Pro access can require a later connection.
3. Data Collection and Local History
Pixel Up does not upload or remotely collect your image contents. The Upscale tool keeps a local history of up to 200 generated outputs, including the output path, file name, dimensions, creation time, and selected model. This history is stored only in %LOCALAPPDATA%\PixelUp\history.json and is not synchronized with external servers. Entries whose output files no longer exist are pruned automatically.
The Pixel Up website uses Google Analytics 4 to measure page visits and clicks to the Microsoft Store. Google may process cookies and online identifiers, browser and device information, and approximate location under its privacy policy. Google signals and advertising personalization signals are disabled in the website tag. Website analytics does not receive your desktop image files, license key, or payment details.
The desktop application itself contains no telemetry, analytics, or third-party tracking scripts.
- We do not operate third-party tracking scripts, advertising trackers, or telemetry beacons inside the desktop software.
- Application settings (such as GPU preferences, selected tile sizes, and output paths) are stored locally in your Windows user profile folder (
%LOCALAPPDATA%\PixelUp\settings.json) and never synced to external servers.
4. Payment Processing & Commercial Orders
Pixel Up Pro checkout opens in your browser and is handled by Polar, the merchant of record. Pixel Up does not process or store payment card details, banking credentials, or billing addresses directly.
No image files, pixel buffers, or output metadata are sent to Polar. Polar collects and processes order, billing, and transaction information under its own privacy policy. A license key is delivered after purchase and used by the application for activation and validation.
