Information we collect

We do not collect your name, email address, keystrokes, number sequence, or detailed training history. We do not track you across apps or websites.

Schulte Grid works as a local practice tool. If you choose to contact support by email, your email address and message are used only to respond to your request.

Local storage

The app stores settings, training records, daily goals, and preferences locally on your device. These detailed records are not uploaded to our servers.

Analytics and third parties

We collect a random installation identifier, app and system version, platform, language, and limited product events such as starting or completing a round, opening history, printing, theme or goal changes, and requesting an App Store review. Event properties are coarse categories such as grid size and duration range. The identifier is hashed before storage. We do not use advertising or attribution SDKs, sell this data, or use it for tracking.

Children's privacy

The app is designed for general attention practice. We do not knowingly collect personal information from children.

Online Schulte grid practice

No. Only the current round is shown in page memory. Starting a new round, refreshing, or leaving the page discards it. Training history, preferences, and goals are not saved in browser storage or on a server. Previously saved web records are removed when this version opens.

iCloud sync (App 1.6.0 and later)

When enabled and available, iCloud synchronizes the latest 100 completed results, daily goal, best 5x5 time, and practice-day progress in your private Apple-managed key-value store. Local copies remain available offline. Use the same Apple Account on your devices. Account caches are separated, and deletion markers prevent old device caches from restoring removed results. Turning sync off does not delete copies already in iCloud. Detailed history is not sent to the developer analytics service. Earlier app versions save locally only.
