This policy explains how Brick Workshop (积木造物) handles information when you use the iOS app or contact support.
1. Information on your device
Brick Workshop requires no account, uses no advertising networks, does not engage in cross-app tracking, and does not collect statistics for analyzing user behavior. We do not sell or rent your personal information, or share it for advertising purposes.
The GLB models you choose are processed on your device. The app does not upload models or projects to us. Models, building plans, project names, previews and building progress are stored locally so you can save and continue projects.
Local preferences such as theme and language preserve your choices. Local state, including free-save counts, is stored using local storage mechanisms provided by iOS to operate app features and manage the free allowance. This information is not uploaded to developer-operated servers.
2. App Store purchases
Apple's App Store handles Pro purchases. The app uses Apple's purchase services to verify purchase status and restore purchased access. We do not receive your card number, full payment account details or Apple Account password.
Apple handles purchase-related information under its privacy policy:
https://www.apple.com/legal/privacy/
3. Network requests and third parties
If a model references textures or other resources on the internet, the app may automatically request those URLs when loading it. Resource providers may receive your IP address, resource URL and necessary request information. You can use a GLB with fully embedded resources to avoid these requests.
The privacy and support pages may use a third-party hosting service. Hosting providers may process access logs, including IP addresses, for security and operational purposes under their privacy practices. The pages themselves use no advertising or visitor analytics. If GitHub Pages is used, its access-log information is available here:
https://docs.github.com/en/pages/getting-started-with-github-pages/what-is-github-pages#data-collection
4. Retention and deletion
Projects, drafts and preferences are stored on your device. You can delete projects on the Projects screen; this does not delete source models stored in Files or elsewhere. Choosing Delete App in iOS removes the app's projects, drafts, preferences and temporary files.
The Home screen automatically keeps your latest creation draft, including parsed model data, generation settings, the latest brick preview and voxel edits, so you can continue after reopening the app. Closing the model on the Home screen clears its model data, preview and voxel edits; generation settings remain. Drafts are not automatically added to Projects.
Importing may create temporary model copies that the system manages and clears. Reinstalling the app does not guarantee a reset of the free allowance. System device backups may include app data and are managed through your backup settings.
The app provides no project cloud sync, and we cannot remotely access or delete your local projects. You can choose not to import files or stop using the relevant features.
5. System file access
The app uses the iOS system file picker to import GLB files you choose for on-device model processing. This version does not request photo-library access.
6. Support emails
If you email support, we receive your email address, message and any screenshots or files you choose to attach. We use this information only to respond, troubleshoot and carry out necessary follow-up, not for advertising or profiling.
We retain support information while handling the issue and necessary follow-up, then delete it or remove identifying information when no longer needed, unless retention is legally required. You can contact the email below to request access, correction or deletion, or withdraw your consent to this processing.
We use Gmail to handle support requests. Google may process related information under its privacy policy:
https://policies.google.com/privacy
7. Children's privacy
This app is not designed for children and does not actively collect children's personal information. If a parent or guardian believes a child has provided personal information to us in a support email, please notify us using the email in Contact us. We will review and handle the request under applicable law.
8. Policy updates
We will update this policy and its date when our information-handling practices change. For material changes to personal-information processing, we will provide notice and obtain consent where required.
