Privacy

Carpentry Math and Projects is a learning aid for carpentry math, visual references, safety topics, and small projects. The app is designed to work from files stored with the app and does not require an account.

Information stored on your device

Lesson completion, project checklist choices, and cut-list entries are saved in local browser storage on your device so they remain available when you return. They are not sent to the app owner by this app.

Photos and device sensors

If you select a room photo, the app displays it locally for your visual review. The photo is not uploaded. The phone tilt-level may read device motion after you start it and allow access. Those readings are displayed in the app and are not transmitted.

Network use

The website version uses the network to load and update the app. It may cache its own static files for offline access. The native iOS package contains a local copy of the app's files. No analytics, advertising, account, payment, or third-party tracking service is included in this release.

Retention and deletion

Saved progress and cut lists remain in local storage until you clear them in the app, clear this website's data in your browser settings, or remove the native app from your device. The publisher does not receive a copy and cannot access or erase your local records remotely.

Children and education

The app is intended as a classroom learning aid. It does not ask users to submit personal information. Students should follow their school or instructor's device and photo policies.

Safety and accuracy

Calculators, photo observations, phone sensor readings, layouts, and project drawings are educational references. They do not replace approved construction documents, qualified inspection, physical measuring tools, instructor supervision, or local requirements.
