How we work

Simple products, fair rules

Privacy by default

We collect only what is necessary. No needless accounts, ads or trackers – your data stays with you.

Speed and reliability

Apps should start fast and keep working with a weak signal. We measure performance instead of guessing.

Reliable data

We use trusted sources, state where the data comes from and under which license, and prepare updates automatically.
