Lumenfoil support

How can we help?

For technical help, purchase questions, privacy requests, feedback, or feature suggestions, email support@lumenfoil.com.

We aim to reply within two business days. Please include your device model, operating-system version, and the steps that led to the problem. Do not send payment-card information.

Projects and local storage

Your Lumenfoil projects are stored locally inside the app’s protected container. If an edit does not appear to save, keep the app installed, reopen the project, and contact us before deleting or reinstalling the app.

Imports and exports

When reporting a problem with a reference file or exported pattern, tell us the source format, intended page size, measurement units, and export format. Share the artwork itself only if you are comfortable doing so and have the right to share it.

Purchases and subscriptions

Apple processes App Store purchases. To manage or cancel a subscription, open Settings on your device, tap your name, then Subscriptions. To recover an eligible purchase, use Restore Purchases inside Lumenfoil. For refunds or billing disputes, use Apple’s purchase-support process.

Cutability guidance

Lumenfoil can flag geometry that may be difficult to fabricate, but its guidance is not a guarantee. Glass type, grain, tools, technique, and pattern scale all affect the result. Review every design with your own judgment and use appropriate workshop safety practices.

Privacy

Read the Lumenfoil Privacy Policy for details about local project storage, exports, purchases, and early-access information. Privacy and deletion requests can be sent to support@lumenfoil.com.

App license

Unless a custom agreement is shown in the App Store, Lumenfoil is provided under Apple’s Standard Licensed Application End User License Agreement.
