FAQ
Frequently asked questions
Are Nalko fitness calculators really free?
Yes. Calculation and results work without an account. A free account is required only when you choose to save a result.
How does Nalko choose which tools to offer?
Every service must answer a distinct intent, use a verifiable method and connect to a tracking feature that actually exists in Nalko.
Do body data appear in the URL?
No. Weight, age, calories and performance values are never added to the page address.
