Your thinking stays yours.

This policy applies to Black Box Logic Lab for iPhone and iPad, published by Dimitar Angelov, and these app information pages.

Gameplay data

The app stores progress, observations, hypothesis notes, settings, achievements, and saved creations on your device. The app does not send this gameplay data to the developer. It does not use advertising, tracking, third-party analytics, or an app account.

Trials and purchases

Apple processes free-trial activation, purchases, and restoration through the App Store. The app uses Apple’s verified transaction information, including the product and original purchase date, to determine access. Payment card details are not provided to the app or developer. Purchase handling is also governed by Apple’s privacy policy.

Diagnostics and support

Diagnostic reports are generated only when you choose to export them. They exclude private hypothesis notes. Nothing is sent automatically: you choose the destination and what to share. Information you voluntarily provide for support is used to investigate and respond to your request.

Your choices

Use Settings → Reset All Progress to remove campaign progress, observations, notes, drafts, achievements, and statistics. This does not reset trial eligibility or remove an App Store purchase. You can remove the app to delete its local data. Purchase history is managed by Apple. Device backups, if enabled, are governed by your Apple settings.

This website

These pages do not include analytics scripts, advertising, or tracking cookies. The hosting provider may process standard technical request information, such as IP address and browser details, to deliver and secure the website. External links have their own privacy policies.

Children

The app does not ask for personal information or use advertising. A parent or guardian may manage App Store purchase permissions through Apple’s account controls.

Changes and contact

Updates to this policy will be posted here with a revised effective date. For privacy questions, email d.angelov@me.com. See the support page for help with the app.
