Client-Side by Design
AquaCalc performs all calculations in your browser using JavaScript. No tank metrics, water parameters, or personal information are sent to a server. Because nothing leaves your device, there is no server-side store of your data to breach.

Static Delivery
The site is a set of static pages served over HTTPS. There is no user account system, database, or authentication layer, which keeps the attack surface minimal.
