Privacy Policy

At Vintix, we build tools that respect your privacy by design. We believe that you shouldn't have to sacrifice your personal details or file security to use basic utility web apps.

No File Uploads for Processing

When you convert an image, crop photos, or upload brand logos to overlay on QR codes, the files are processed entirely inside your local browser sandbox. They are decoded and compressed locally using WebAssembly and Web Workers. We do not maintain any conversion APIs, cloud databases, or remote file servers, which means your sensitive files never travel over the network.

Local QR Code Generation

Traditional QR generator sites route your Wi-Fi passwords, contact cards, private text messages, or site URLs through their servers to generate the code image. Vintix does this completely client-side in JavaScript. Your private payloads remain strictly in the browser tab memory.

Temporary Memory and Sandbox Lifecycle

Your uploaded assets and generated images temporarily occupy the browser's local RAM. We create temporary local Object URLs so that the browser can display previews and trigger downloads. Once you close or reload the browser tab, this memory is automatically cleared by the browser's garbage collection.

Harmless Local Preferences

Vintix does not use tracking cookies or analytics software. We save a small number of configuration preferences inside the browser's `localStorage` to improve your workflow:

Your selected UI theme setting (Light, Dark, or System).
Your last used QR export download format preference (PNG, SVG, WebP).
Your preferred image conversion format and quality thresholds.

We never save private QR input strings, Wi-Fi credentials, or calendar details to `localStorage` or any form of persistent browser cache.

Architecture & Security Scope

While Vintix is engineered as a client-side utility sandbox, we do not claim that we can never access anything under any circumstance. Security is a shared responsibility:

Browser Extensions: Malicious browser extensions or spyware on your local device may be able to read input fields or screen captures. Keep your browser and extensions up to date.
Network Delivery: The Vintix website files (HTML, JavaScript, WASM modules) are delivered to your browser via secure HTTPS. If your network connection is intercepted, or if hosting assets are compromised, the scripts could theoretically be modified. We utilize standard SSL certificates and secure CDN delivery to minimize this risk.
