Zero-Upload Architektur (RAM-Only)
Alle Berechnungen und Generierungen laufen ausschliesslich lokal im Arbeitsspeicher (RAM) deines Geräts über native Browser-Schnittstellen (HTML5 Canvas, Web APIs & WebAssembly). Es werden null Bytes an einen Server gesendet.
PrivatTools processes business cards, Swiss QR-Bills, PDFs and images exclusively inside your device’s local memory (RAM). Hosted in Switzerland at Infomaniak – no cloud uploads, no tracking traps.

Traditional online converters and QR generators upload your sensitive contacts, contracts or photos to third-party servers. PrivatTools flips this model: we only ship static application code to your browser – your device does all the work locally.
All inputs are processed via HTML5 Canvas, Web Crypto API and WebAssembly directly in your device’s local memory. As soon as you close the tab, your RAM is cleared.
Recurring details (such as your company address for vCards or Swiss QR-Bills) can optionally be saved in your own browser’s localStorage – never in an external database.
Delivered from Infomaniak’s Swiss data centers (Geneva/Winterthur). Because no upload backend exists, neither we nor third parties can ever inspect your files (Swiss FADP & GDPR compliant).
