Privacy Policy

Effective September 23, 2026

Information we collect

Blacklink Keys does not collect any personal information. There are no accounts, and we do not ask for names, email addresses, or any other details about you.

Information stored on your device

Your progress (stars, XP, scores, settings, and the date you agreed to this policy) is saved in your browser's local storage on your device. It is never sent to Blacklink or anyone else. Clearing your browser data, or using a different device, starts a new profile.

Tracking and advertising

We do not use analytics, cookies, or advertising. The app loads only from its own server and Blacklink's icon service (cdn.blacklink.net). Like any website, these servers receive the basic technical information needed to deliver a page, such as your IP address; we do not use it to identify or track you.

Children

Blacklink Keys is built for K–12 students. Because it collects no personal information, it can be used without creating an account or sharing any details about a student.

Changes

If this policy changes, the updated version will be posted on this page.
