Your builds stay on your device.

Data stored on your device

The app saves the wheel builds you create (measurements, calculated lengths, notes, tags and folders), the photos you attach to them, and your settings. This data is stored in the app's private storage on your device and is never sent to the developer or to any server.

Your device's own backup (for example iCloud Backup or Android backup) may include this data, under the terms of your Apple or Google account.

Camera and photo library

The app asks for access to the camera or the photo library only when you choose to attach a photo to a build. Photos you take or pick are kept with that build on your device. The app does not read other photos and does not upload anything.

In-app purchase

The one-time Builds unlock is sold through the App Store or Google Play. Payment is handled entirely by Apple or Google; the app receives only a confirmation that the purchase was made, which it keeps on your device. The developer does not receive your name, email or payment details. The privacy policies of Apple and Google apply to the purchase.

Exporting and sharing

When you export builds to CSV, share a build as text or share a photo, the app hands the data to the system share sheet. Where it goes next is your choice, and the app does not keep a copy elsewhere.

Contacting support

If you email support, your email address and the content of your message are used only to answer you and are not shared with anyone. You can ask for your messages to be deleted at any time.

Children

The app is not directed at children and does not knowingly collect any data from anyone, including children.

Changes to this policy

If the app's handling of data changes, this page will be updated and the date below changed.

Effective date: 5 October 2026
