needing an internet connection and without asking for any permissions.

The app covers 12 categories and more than one hundred individual units.
You can convert length, mass, temperature, area, volume, time, speed,
data storage, energy, pressure, frequency, and fuel economy. Each
category includes both metric and imperial units where applicable, so
you can move between systems with ease.

kilometer, inch, foot, yard, mile, and nautical mile. Mass includes
microgram, milligram, gram, kilogram, metric ton, ounce, pound, stone,

The interface is built with Material 3 and supports both light and dark
themes. Right-to-left language layouts are supported. The app is
lightweight, opens quickly, and runs on Android 7.0 and newer.

Privacy is a core part of the design. The app does not request any
runtime permissions. It does not access the internet, your contacts,
your location, your files, your camera, or your microphone. There are
no ads, no sign-up, no account, and no tracking. Your inputs stay on
your device.

Alhaya Unit Converter is suitable for students working through physics,
chemistry, or math problems, for engineers and technicians who need
quick reference values, for cooks converting between metric and
US or UK measures, for travellers comparing distance, speed, and fuel
units, and for anyone who simply wants a converter that opens and
works.

The app is built and maintained as an independent Android project.
