Tinkerhall

The short version

Tinkerhall collects nothing. There is no account, no advertising, no tracking and no analytics, and nothing you do in the app is sent to the developer or to anyone else.

What the app does on your device

All the models, pictures and facts are inside the app and are drawn on your device. The app does not make network requests and shows no ads or third-party content.

What stays on your device

• Your favourite models.
• Your Inventor Passport counts: models explored, tours finished, blueprints drafted.
• Your appearance choice (System, Light or Dark) for the current session.

This is stored in the app's own settings on your device. Deleting the app deletes it.

Blueprints and sharing

A Blueprint is made on your device. When you copy it, save it or share it, it goes only where you choose, using the system's own copy, file or share sheet. Tinkerhall does not see where it goes and asks for no access to your photos.

Permissions

Tinkerhall asks for none: no location, camera, microphone, contacts, photos or tracking.

Children

Tinkerhall is written for curious teens and adults and collects no personal information from anyone, including children. It has no ads, accounts or links that lead out of the app other than the ones you choose in Settings (rating the app and emailing the developer).

Changes and contact

If this policy ever changes, the new version will be posted on this page with the date. Questions: support@khangazun.com.
