Privacy policy

Last updated: 23 September 2026 · Published by Eric Bagnaro, Lyon, France · support@kalkomaths.com

In short

Kalko collects no personal data. There is no account, no sign-in, no advertising and no analytics software in the app.

A children's app

Kalko is designed for children aged 6 to 11 and is published in the App Store Kids Category. Because we collect no personal information from anyone, including children, no parental consent is required under the United States Children's Online Privacy Protection Act (COPPA) or article 8 of the European General Data Protection Regulation (GDPR).

What stays on the device

The first name your child types, progress, levels, trophies and statistics are stored only on the iPhone, in the app's own storage. We have no access to them and they are never transmitted. Deleting the app deletes them.

No third parties in the app

Kalko contains no advertising, no third-party analytics and no social media components. It makes no network requests, and works with no internet connection.

Apple's role

Kalko is sold through the App Store. Apple processes your purchase and provides us with anonymous, aggregated sales and usage statistics that do not identify anyone. Apple's handling of your purchase is governed by Apple's own privacy policy.

Links out of the app

Links to this website, to the App Store rating page and to Apple's terms sit behind a parental gate so that a child cannot follow them unsupervised.

This website

kalkomaths.com uses no cookies, no analytics and no tracking. Fonts are served from our own server, not from a third party. Our hosting provider may keep standard technical logs, including IP addresses, for security purposes, as any web server does.

Your rights

Since no personal data is collected, there is nothing to access, correct or delete on our side. You may write to us with any question at support@kalkomaths.com.

Changes

Any change to this policy will be published on this page with a new date. If a future version of Kalko ever collected data, it would be stated here and in the update notes before the feature shipped.
