Privacy

This page explains the data used by the Cubeline trainer. Updated 17 September 2026.

Practice data

The trainer stores your settings, learned checkboxes, selected algorithms and solve history in your browser’s local storage under cubeline.v1. The app does not send this practice data to a trainer database. Exporting creates a file on your device; importing reads the file you choose.

Hosting

When you visit the site, the hosting service receives technical information needed to deliver it, such as your IP address and request details. Hosting is provided through OpenAI Sites. See OpenAI’s privacy policy for information about its handling of data.

Advertising and analytics

Advertising is not active in this version. The trainer does not load an ad network or analytics tracker. If advertising is enabled later, this page will describe the provider and the available consent choices.

External links

Sources and video tutorials open on other websites. Visiting those websites is subject to their own privacy practices. Tutorial videos are linked rather than embedded.

Managing your information

You can export your practice data in Settings & data. To remove it, clear this site’s storage in your browser. Clearing storage removes the local checklist and solve history; keep an export first if you want to restore them later.
