Your data stays with you
Every calculator, decoder and file converter on this site runs entirely in your browser. Values you type and files you open are processed locally by JavaScript and are never transmitted to us or to any server. There are no upload endpoints, no accounts and no databases behind this site — it is served as static files.
What is stored locally
Two items of localStorage: your dark/light theme preference and your language choice. Both stay in your browser and are not readable by us. No other client-side storage is used by the site itself.
Analytics
We run no analytics and no tracking scripts of our own.
Advertising
The site is ad-supported. When advertising is active, we prefer EthicalAds, a network that serves contextual ads without cookies, tracking or personal-data collection. If Google AdSense units are ever enabled, a consent dialog compliant with Google's requirements will be shown first, and Google's own privacy policy applies. Ad scripts are the only third-party requests this site makes.
