Privacy Policy

Last updated: June 26, 2026

The short version

Kaliber does not collect your data. The app runs entirely on your device, works without an account, and does not send your race, body, or product information anywhere.

What we collect

Nothing. Kaliber performs every fueling calculation locally on your iPhone. The details you enter — your race, your body metrics, and the products you carry — stay on your device. We do not require an account, we do not operate servers that receive your data, and we run no analytics or tracking inside the app.

How we use it

Because we collect nothing, there is nothing for us to use, sell, or share. We do not transfer your information to third parties, because we never receive it in the first place.

Data retention & deletion

Your plans and inputs live only on your device, under your control. Deleting the app removes them. There is no account to close and no server-side copy for us to delete, because none exists.

Children's privacy

Kaliber is intended for a general audience and does not knowingly collect information from anyone, including children.

Changes to this policy

If a future version of the app changes what it collects, we will update this policy and the App Store privacy details before that version ships, and revise the date above.
